About PayWay REST API

This page describes the PayWay REST Application Programmer Interface.

Access to the API depends on the PayWay modules you have purchased.

The PayWay Net module allows you to:

  • Create a check-out or donations page and process one-time credit card payments
  • Maintain full control over the customer experience and styling
  • Reduce your PCI-DSS compliance scope by not processing or storing credit card details on your server.

Find out how to accept online payments and reduce PCI-DSS scope.


The PayWay Recurring Billing and Customer Vault module allows you to:

  • Store credit card and bank account details in the PayWay customer vault
  • Take payments using the stored details individually or using a file
  • Reduce your PCI-DSS compliance scope by not processing or storing credit card details on your server
  • Schedule regular collection of payments from a customer.

The PayWay Match module allows you to:

  • Open virtual accounts for customers who pay you by direct debit/pay anyone.

When a customer pays you by direct credit, PayWay matches the payment to the customer.

Find out how to automatically match EFT payments to customers.


The PayWay Batch module allows you to:

  • Process a file of credit card payments
  • Download reports indicating which payments were approved or declined.

The PayWay Connect module allows you to:

  • Download a machine-readable file listing all received payments for a day.

You can then upload the file into your accounting package.

Other APIs

PayWay supports other ways to interface with your software:

Basics

Versioning and base URL

Current version

The current version of this API is version 1.

Base URL

The base URL of the PayWay REST API is https://api.payway.com.au/rest/v1/.

The URLs on this page are relative to the base URL.

Transport layer security

You must connect using https supporting at least TLS version 1.2.

Backwards compatible changes

We will release a new major version of the API if any backwards incompatible changes are made.

If you believe we have made a backwards-incompatible change, please report a defect.

Resources

The following changes to resources will not result in a new API version:

  • adding new resources
  • supporting new HTTP verbs
  • adding new optional request parameters
  • adding new properties or XML elements in responses
  • changing wording of error message designed to be displayed to users
  • improved error reporting when an invalid request is received.

Write your software to handle these types of changes.

Javascript

The following changes to payway.js will not result in a new API version:

  • changing resources used internally by payway.js
  • adding new properties to objects passed to callback functions
  • adding new optional properties to payway.js functions you call
  • modifying messages posted between payway.js and an iframe hosted by us.

Write your software based on the documented API.

Security

The following changes will not result in a new API version:

  • adding or removing TLS ciphers
  • changing supported TLS versions
  • changing the PayWay server SSL certificate or which certificate authority signs this certificate
  • other changes made to improve security.

Authentication

Basic authentication

You must send an API key as the Basic Authentication username. Leave the password blank.

API keys

There are two types of keys:

  • Your publishable API key is used by payway.js to send credit card details directly from the browser to PayWay
  • Your secret API key allows your server to process payments and provides full access to the API
Treat your secret API key like a password.

Obtaining an API key

To develop and test, get a free PayWay test facility.

To purchase a live PayWay facility, contact us.

Once you have a sign in to view and manage your API keys:

  1. Sign in to PayWay
  2. Click Settings
  3. Click REST API Keys

Secret API keys expire after one year and then you must use a new key. You can automate secret API key renewal.

To test authentication, send a GET to the base url.

Sending requests

HTTP verbs

The standard HTTP verbs are used.

Verb Purpose
GET Read a resource
PUT Create or replace a resource when URL is known
POST Create a resource when URL is not known
PATCH Update details of a resource
DELETE Delete a resource
If you send a PUT request and omit a field, the server removes or defaults the field value.

Requesting JSON or XML

To request JSON responses, send this header:

Accept: application/json

To request XML responses, send this header:

Accept: application/xml

Sending fields for PUT, POST and PATCH

Use the x-www-form-urlencoded content type for sending fields in PUT, POST and PATCH requests.

You must send this header:

Content-Type: application/x-www-form-urlencoded

The request body must contain name/value pairs which have been URL encoded. Use a standard library for URL encoding.

Uploading files

Use the multipart/form-data content type for uploading files.

You must send this header:

Content-Type: multipart/form-data

Use cUrl or a standard library to create the request.

Avoiding duplicate POSTs

You should set a unique value for the Idempotency-Key header on POST requests. Use a UUID for your idempotency key. For example:

Idempotency-Key: a1b22c16-4870-428c-a199-6203cbec7290

This allows requests to be retried after a network failure without accidental duplication. If you receive a network error or timeout, you should resend the request with the same Idempotency-Key.

If you resend a POST request with the same value for the Idempotency-Key, you will receive the original response. If the server is still processing the original POST, you will receive 429 Too Many Requests.

Idempotency keys expire after 24 hours. The maximum length is 60 ascii characters.

Error handling

If you receive a HTTP response code from 200 to 299, the server has accepted your request. When you create a transaction or file you must also check the status in the response body.

If you receive one of these responses, wait 20 seconds and then resend the request with the same Idempotency-Key:

If you receive a 422 Unprocessable Entity you may display the error message to your user and allow them to correct the data.

If you receive any other response code, you should log the response code and response body. See: HTTP Response Codes.

You can follow links returned in responses to related resources. This is known as HATEOAS.

Links are returned in the format shown in the examples.

Open help link URLs in your browser to access developer help (usually this page).

Example links in JSON response

{
"data" : [ {
    "example": "one"
  }, {
    "example": "two"
  }
],
"links" : [ {
    "rel" : "prev",
    "href" : "https://api.payway.com.au/example?page=2"
  }, {
    "rel" : "next",
    "href" : "https://api.payway.com.au/example?page=4"
  }
  ]
}

Example links in XML response

<examples>
<data>
  <example>one</example>
  <example>two</example>
</data>
<links>
  <link rel="prev"
        href="https://api.payway.com.au/example?page=2" />
  <link rel="next"
        href="https://api.payway.com.au/example?page=4" />
</links>
</examples>

Lists of items

Resources which return lists use a standard structure:

  • The data JSON property (or XML element) holds up to 20 items
  • More results can be found by following next and prev links.

Search URLs

Search URLs are templates:

/search-example?customerNumber={customerNumber}

You must replace parts delimited by braces with actual values.

Dates and times

Dates with no time component are formatted as dd MMM yyyy. An example of such a date is the settlement date, which groups together transactions which are part of the same logical banking day.

Dates with a time component (such as when an event happened) are formatted as dd MMM yyyy HH:mm z. In this case, z represents the timezone.

A credit card expiry month is treated as a two digit string. A credit card expiry year is treated as a two digit string. This matches what is printed on credit cards.

Example of date and times in JSON response

{
"settlementDate": "05 May 2015",
"transactionDateTime": "05 May 2015 13:00 AEST",
"expiryDateMonth": "01",
"expiryDateYear": "22"
}

Example of date and times in XML response

<example>
  <settlementDate>05 May 2015</settlementDate>
  <transactionDateTime>05 May 2015 13:00 AEST</transactionDateTime>
  <expiryDateMonth>01</expiryDateMonth>
  <expiryDateYear>22</expiryDateYear>
</example>

Tutorials

Trusted frame

Use this tutorial to create a server-side rendered web page that takes a one-off credit card payment or stores credit card details in the customer vault. Your server will not store or process credit card details.

This iframe solution allows you to be compliant with PCI-DSS SAQ A. This is the easiest level of compliance.

It works as follows:

  1. Your server hosts a web page containing a form and payway.js
  2. You call createCreditCardFrame which creates a PayWay iframe for collecting credit card details
  3. The iframe sends credit card details securely to PayWay
  4. The iframe sends a single use token to your website
  5. Your server uses the token in place of the credit card details when you take a payment or create a customer in the customer vault.
If you want to receive the token via a javascript callback see Trusted frame (SPA).

Step 1: Host example page

Host this page on your website. Cardholders will enter their details on this page.

<!DOCTYPE html>
<html>
  <body>
    <!-- this form will POST a single use token to your server -->
    <form action="/process-payment" method="post">
      <div id="payway-credit-card"></div>
      <input id="payway-cc-submit" type="submit" disabled="true"/>
    </form>
    <script src="https://api.payway.com.au/rest/v1/payway.js">
    </script>
    <script type="text/javascript">
      var submit = document.getElementById('payway-cc-submit');
      payway.createCreditCardFrame({
          publishableApiKey: '{publishableApiKey}',
          onValid: function() { submit.disabled = false; },
          onInvalid: function() { submit.disabled = true; }
      });
    </script>
  </body>
</html>

Open the page. You should see this error message:

You must replace {publishableApiKey} with your publishable API key when calling payway.createCreditCardFrame()

Step 2: Set publishable API key

  1. Sign in to PayWay
  2. Click Settings
  3. Click REST API Keys
  4. Click your publishable key (or add a new one)
  5. Copy the key
  6. In your web page, replace {publishableApiKey} with your publishable key.

You may also change /process-payment to a URL you prefer.

Step 3: Test page

Load your web page, you should see the credit card form.

Screenshot of credit card form

Enter these card details:

Field Value
Card Number 4564 7100 0000 0004
Security Code 847
Name on Card Token Tutorial
Expiry Date 02 / 29

Click Submit.

Your browser will POST to /process-payment on your server. The POST includes a parameter like this:

singleUseTokenId: 2bcec36f-7b02-43db-b3ec-bfb65acfe272

Step 4: Take payment or save credit card

You can now use the single use token to take a payment or save the credit card to the PayWay customer vault.

When you receive a POST to /process-payment you should:

  1. Read the single use token from the parameter
  2. Verify your customer using a session cookie
  3. Using your secret API key and the single use token, send a request to take a one-time payment.

If you need to take more than one payment with the credit card details, you should store the credit card, optionally verify the stored card and then take payments using stored details.

Step 5: Improve your solution

You must now improve your solution by:

You may also wish to:

Trusted frame (SPA)

Use this tutorial to create a single-page application (SPA) that takes a one-off credit card payment or stores credit card details in the customer vault. Your server will not store or process credit card details.

This iframe solution allows you to be compliant with PCI-DSS SAQ A. This is the easiest level of compliance.

It works as follows:

  1. Your single page application fetches payway.js
  2. You call createCreditCardFrame which creates a PayWay iframe for collecting credit card details
  3. The cardholder enters their details in the frame
  4. You call frame.getToken and the iframe sends credit card details securely to PayWay
  5. The iframe makes a callback to your application passing a single use token
  6. You send the single use token to your server using ajax
  7. Your server uses the token in place of the credit card details when you take a payment or create a customer in the customer vault.

Step 1: Host example page

Host this page on your website. Cardholders will enter their details on this page.

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>PayWay Trusted Frame Example Code</title>
    <meta charset="UTF-8">
  </head>
  <body>
    <h1>PayWay Trusted Frame Example</h1>

    <div id="payway-credit-card">
    </div>

    <br/>

    <button id="pay" disabled>Pay</button>

    <script src="https://api.payway.com.au/rest/v1/payway.js">
    </script>

    <script>
      "use strict";
      const payButton = document.getElementById( "pay" );
      let creditCardFrame = null;

      const tokenCallback = function( err, data ) {
        if ( err ) {
          console.error( "Error getting token: " + err.message );
        } else {
          // TODO: send token to server with ajax
          console.log( "singleUseTokenId: " + data.singleUseTokenId );
        }
        creditCardFrame.destroy();
        creditCardFrame = null;
      };

      payButton.onclick = function() {
        payButton.disabled = true;
        creditCardFrame.getToken( tokenCallback );
      };

      const createdCallback = function( err, frame ) {
        if ( err ) {
          console.error( "Error creating frame: " + err.message );
        } else {
          // Save the created frame for when we get the token
          creditCardFrame = frame;
        }
      };

      const options = {
        // TODO: Replace {publishableApiKey} with your key
        publishableApiKey: "{publishableApiKey}",
        tokenMode: "callback",
        onValid: function() { payButton.disabled = false; },
        onInvalid: function() { payButton.disabled = true; }
      };
      payway.createCreditCardFrame( options, createdCallback );
    </script>

  </body>
</html>

Open the page and open the javascript developer console.

You should see this error message:

You must replace {publishableApiKey} with your publishable API key when calling payway.createCreditCardFrame()

Step 2: Set publishable API key

  1. Sign in to PayWay
  2. Click Settings
  3. Click REST API Keys
  4. Click your publishable key (or add a new one)
  5. Copy the key
  6. In your web page, replace {publishableApiKey} with your publishable key.

Step 3: Test page

Load your web page, you should see the credit card form.

Screenshot of credit card form

Enter these card details:

Field Value
Card Number 4564 7100 0000 0004

Name on Card Token Tutorial
Expiry Date 02 / 29

Click Pay.

The single use token will be logged to the javascript console.

singleUseTokenId: 2bcec36f-7b02-43db-b3ec-bfb65acfe272

Step 4: Send token to server

You must now write code to send the token to your server using ajax.

Step 5: Take payment or save credit card

Your server can now use the single use token to take a payment or save the credit card to the PayWay customer vault.

  1. Read the single use token from the ajax endpoint
  2. Verify your customer using a session cookie
  3. Using your secret API key and the single use token, send a request to take a one-time payment.

If you need to take more than one payment with the credit card details, you should store the credit card, optionally verify the stored card and then take payments using stored details.

Make sure the cardholder can not tamper with the payment amount before your sever sends it to PayWay

Use cURL to check network

For your software to work, your server must be able to connect to PayWay. Use this tutorial to determine if a problem is with your network or your software.

Step 1: Download and install cURL

Download and install the cURL client for your platform from http://curl.haxx.se/download.html . Be sure to download the correct distribution for your server's operating system. You must download a version that includes SSL support.

If you are using Windows, we recommend that you download the binary distribution listed under the heading Win32 - Generic labelled Win32 2000/XP, binary and SSL and maintained by Günter Knauf. This document does not provide a direct link because you should always download the latest version.

Step 2: GET the root resource for the API

To test if your server can connect to PayWay:

curl -i --basic --user "{publishableApiKey}:" https://api.payway.com.au/rest/v1

Replace {publishableApiKey} with your Publishable API Key.

If you receive the expected response, your network is working.

Troubleshooting

HTTP Response codes other than 200

See HTTP Response Codes.

curl: (60) SSL certificate problem: unable to get local issuer certificate

Your server does not trust the server TLS certificate presented by PayWay. Typically, this is due to an out-dated root CA certificate bundle on your server. Download and install an updated Entrust Certification Authority - L1M root certificate for your server.

curl: (56) Received HTTP code 407 from proxy after CONNECT

Your network has a proxy server. To test if your server can connect to PayWay through the proxy server:

curl --proxy {proxyServer} --proxy-user {proxyUsernamePassword} -i --basic --user "{publishableApiKey}:" https://api.payway.com.au/rest/v1

Your software must connect to PayWay through the proxy server.

curl: (6) Couldn't resolve host 'api.payway.com.au'

DNS resolution failed. You may need to authenticate with your proxy server.

  • Automating the process by creating a scheduled task - refer to your operating system's documentation
  • Import the file you have downloaded into your accounting system
Other references:

Troubleshooting

curl: (22) The requested URL returned error: 404 Not Found

PayWay does not have a receipts file for the requested settlement date. PayWay creates files shortly after 3 am Sydney time each day. The receipts file contains transactions from the previous settlement day. Receipts files are available for 365 days.

To see which receipts files are available:

  1. Sign in to PayWay
  2. Click Receipts Files under the Reports menu
curl: (23) Failed writing body (0 != 1)

You have already saved the receipts file to the current folder. To save a new copy:

  • Backup the receipts file already saved
  • Delete the receipts file
  • Run the command again
curl: (60) SSL certificate problem: unable to get local issuer certificate

Your server does not trust the server TLS certificate presented by PayWay. Typically, this is due to an out-dated root CA certificate bundle on your server. Download and install an updated Entrust Certification Authority - L1M root certificate for your server.

curl: (56) Received HTTP code 407 from proxy after CONNECT

Your network has a proxy server. To test if your server can connect to PayWay through the proxy server:

curl --proxy {proxyServer} --proxy-user {proxyUsernamePassword} -i --basic --user "{publishableApiKey}:" https://api.payway.com.au/rest/v1

Your software must connect to PayWay through the proxy server.

curl: (6) Couldn't resolve host 'api.payway.com.au'

DNS resolution failed. You may need to authenticate with your proxy server.

  • Polling the status of your file
  • Downloading errors in your file and reporting them to your staff

Resources

PayWay allows you to store credit card and bank account details against your customers. You can process payment transactions using the stored details.

You can open virtual accounts for customers who pay you by direct credit/pay anyone. Each of your customers uses a different virtual account. When a payment is sent to a virtual account, PayWay matches the payment to that customer.

Upload a payment file to process transactions in bulk.

Single use tokens are used to avoid processing credit card details on your server.

Your merchants and your bank accounts are used for transaction processing and settlement.

Custom fields allow you to store extra information against each customer.

PayWay can calculate and apply surcharges.

Download receipts files containing a machine-readable list of payments received.

The base URL of the PayWay REST API is https://api.payway.com.au/rest/v1/.

Root

This resource is the top level of the REST API.

To test your network connectivity and API key is working correctly, send a GET to this resource.

Get root resource

GET /

You may access this resource with either your secret or publishable API key.

Model

Field Notes
clientNumber Issued by us to uniquely identify your PayWay facility
clientName The name of your business
keyName The name of the API key you sent

The response includes links to top level resources.

Transactions

Transactions may be payments, refunds, pre-authorisations, captures or account verifications. An account verification checks if a customer's credit card is valid. A pre-authorisation reserves money on your customer's credit card. Later, a capture debits the reserved money.

You can:

To get all transactions processed on a day, see Receipts Files.

Besides this API, PayWay also has other ways to process payments.

Take payment

To take a one-time credit card payment, first get a single use token and then:

POST /transactions

You must send:

Single use tokens

Single use tokens allow you to avoid sending credit card or bank account details to your server.

Tokens are temporary. To store a credit card or bank account, use a token to create a customer in the customer vault.

Your PCI-DSS compliance scope is reduced when your server does not store or process credit card details.

Tokenise credit card (webpage)

To add a PayWay iframe containing credit card fields to your page, include payway.js, create a div with id payway-credit-card, and call payway.createCreditCardFrame.

For step-by-step instructions, see the Trusted Frame tutorial.

For JavaScript reference, see payway.js.

</singleUseToken>

If you send invalid fields, you will receive a 422 Unprocessable Entity response.

3-D Secure Authentication

Authentication is the process of confirming that the person making an e-commerce transaction is entitled to use the payment card.

When you create a single use token and the response indicates threeDS2AuthRequired=true, your next step is to authenticate.

Authenticate

To authenticate the credit card stored in a singleUseToken using 3-D Secure 2:

POST /single-use-tokens/{singleUseTokenId}/three-ds2-authentication

Send these fields:

Use your secret API key.

You should send an Idempotency-Key to ensure authentication requests are not duplicated if there is a network problem.

Make sure the cardholder can not tamper with these fields before your server sends them to PayWay.

Receipts files

Receipts files contain a machine-readable list of payments received.

PayWay can generate receipts files suitable for upload into various accounting software packages. For file specifications, see Receipts files formats. We recommend the RECall File format.

Receipts files include payments processed through all PayWay modules. PayWay creates files shortly after 3 am Sydney time each day. The receipts file contains transactions from the previous settlement day. Receipts files are available for 365 days.

Download receipts files

For step-by-step instructions for configuring and downloading a receipts file, see the Use cURL to download a receipts file tutorial.

To download a receipts file in your selected format:

Subaccounts

Settlement is the process of paying you for transactions which have been processed. To settle to many different Westpac bank accounts, use subaccounts.

PayWay will use the start of the customer reference number to select the settlement account for each transaction.

This is useful if you collect payments on behalf of many different legal entities.

Customer reference number

If your bank account or merchant is set up to use subaccounts, you must generate your customer reference number in this format:

Digit Position Notes
1 to 6 6 digit prefix allocated by us, indicating the account to use for settlement
7 to 13 7 digits allocated by you, allowing you to reconcile transactions to your customers
14 Check digit calculated by you using Luhn algorithm, validated by us

To set up subaccounts, choose this option when you purchase PayWay.

Subaccounts are not available in PayWay test facilities.

Surcharges

PayWay can apply surcharges on your behalf. Credit card surcharges are percentage based. Direct debit surcharges are a flat amount.

To take payments, send the principal amount. PayWay calculates the surcharge amount. The response includes the principal, surcharge and total payment amount.

Each customer's payment setup includes the surcharge rate payable by that customer. Payments using a customer's stored payment setup use that rate. Otherwise, the facility surcharge rates are used.

When using trusted frames, to display the surcharge rate to the customer use the rate from the token callback.

For more information, including how to set rates, see Payment Surcharges in PayWay.

HTTP response codes

The following response codes are used.

200 OK

The request has succeeded.

201 Created

The server has created the resource you requested.

If you created a transaction, you must use the status field to determine if the transaction was approved.

If you create a payment file, you must use the status field to determine if the file has errors or is being processed.

202 Accepted

The request has been accepted for processing, but the processing has not completed.

This response code is returned if the credit card network is slow to respond when processing a transaction. The status of the transaction will be pending.

To find out if the transaction is approved or declined, send a request to get transaction details.

204 No content

The server has fulfilled the request.

This response code is returned when a DELETE is successful.

400 Bad request

The request could not be understood by the server due to malformed syntax.

This response code is returned if the Idempotency-Key header is too long.

This response code is returned if you send query parameters on a PUT, POST or PATCH request. See Sending Fields for PUT, POST and PATCH.

401 Unauthorised

The server can not authenticate the details in the Authorization header. The response body contains more specific information.

This indicates that you have not passed a valid API key, the key has expired, or the Authorization header is not formatted correctly. Correctly formatted requests include a header like this:

Authorization: Basic cGFzc3dvcmQ=

The letters after Basic are the base-64 encoded representation of your API key.

See authentication for information on API keys.

Cross-Origin Resource Sharing

You may not call the PayWay REST API using Ajax.

To send credit card or bank account details from the browser to PayWay, implement the Trusted Frame solution. Using an iframe provides additional security and minimises your PCI-DSS scope.

If a resource requires your secret key, send the request from your server. For security, only your server is allowed to take payments, process refunds, download receipt files, etc.

403 Forbidden

A valid API key was provided, but it does not have access to the requested resource.

Incorrect API key

Check if you have provided your publishable key when you should have provided your secret key. See authentication for information on API keys.

PayWay module required

To process one-time payments using a single use token, you must have the PayWay Net module.

To create customers with a stored payment setup, you must have the PayWay Recurring Billing and Customer Vault module.

To create customers with virtual accounts, you must have the PayWay Match module.

To download receipts files, you must have the PayWay Connect module.

To upload payment files, you must have the PayWay Recurring Billing and Customer Vault module, or the PayWay Batch module.

You can contact us to add a module.

PayWay setup incomplete

If you receive the following message, you should contact us.

Your implementation manager must complete the following tasks before you can continue:

404 Not found

The server has not found anything matching the Request-URI.

The response body may contain more information.

Example 404 JSON response

{
  "data" : [ {
    "fieldName" : "transactionId",
    "message" : "Invalid transaction id.",
    "fieldValue" : "99999999"
  } ]
}

Example 404 XML response

<errors>
  <data>
    <error>
      <fieldName>transactionId</fieldName>
      <message>Invalid transaction id.</message>
      <fieldValue>99999999</fieldValue>
    </error>
  </data>
 </errors>

405 Method not allowed

A request was made of a resource using a request method not supported by that resource.

For example, you sent a POST to a resource that only allows GET.

Refer to the documentation of the resource for supported methods.

406 Not acceptable

The server can not send the representation requested by the client.

See Requesting JSON or XML.

407 Proxy authentication required

This error is returned by your proxy server, not PayWay.

You need to configure a proxy user name and password in order to access the internet. You can use cURL to check network connectivity.

See HTTP Status Code Definitions.

409 Conflict

The server can not process the request as it has conflicted with another request.

This occurs if you attempt to create two customers with the same customer number simultaneously.

This also occurs if you attempt to upload a payment file with a duplicate name.

See Avoiding Duplicate Posts.

410 Gone

The server no longer has the resource.

This occurs if you attempt to download a receipts file which is no longer available. For transactions older than 365 days sign in and download the Monthly Settlement or Yearly Settlement reports.

415 Unsupported media type

The server can not process the content type which was provided, or the request is not allowed to have any content.

See:

422 Unprocessable entity

The server can not process the content of the request.

The response body indicates which parameters are in error. You may display the error messages to users.

You should resend the request with corrected parameters.

You must not rely on specific wording. We may change the wording of error messages without notification.

Example 422 JSON response

{
  "data" : [ {
    "fieldName" : "customerNumber",
    "message" : "Please complete this field.",
    "fieldValue" : ""
  }, {
    "fieldName" : "principalAmount",
    "message" : "Invalid amount.",
    "fieldValue" : "x"
  } ]
}

Example 422 XML response

<errors>
  <data>
    <error>
      <fieldName>customerNumber</fieldName>
      <message>Please complete this field.</message>
      <fieldValue></fieldValue>
    </error>
    <error>
      <fieldName>principalAmount</fieldName>
      <message>Invalid amount.</message>
      <fieldValue>x</fieldValue>
    </error>
  </data>
</errors>

429 Too many requests

You have sent too many requests in a given amount of time.

If you send more than 6 simultaneous requests, you may receive this response code.

If you resend a POST with an Idempotency-Key before the server has processed the original request, you will receive this response code.

You should wait for 20 seconds and resend the request with the same Idempotency-Key.

Token quota exceeded

A quota of 100 unused single use tokens applies. Immediately after obtaining a token, you should use it to create or update a customer. If you exceed the quota, it is likely that you are creating tokens and not using them. Tokens expire after 10 minutes. After they expire, you can create more.

500 Internal server error

The server encountered an unexpected condition which prevented it from fulfilling the request.

You should not resend the request. The server may have completed some of the request processing. If you resend a POST, you may cause duplicate processing. e.g. charge the customer twice.

Contact PayWay Technical Support. Provide the following information:-

  • your client number
  • the method you sent in the request (e.g. GET, POST)
  • the URL you sent in the request
  • the date/time of the request
  • the response body returned by the server (if any).
Never email your secret API key. Email is not secure.

Example 500 JSON response

{
  "errorNumber" : 1,
  "traceCode" : "403686"
}

Example 500 XML response

<error>
  <errorNumber>1</errorNumber>
  <traceCode>403686</traceCode>
</error>

501 Not implemented

The server does not recognise the request method. Use one of the standard HTTP verbs.

See HTTP Verbs.

503 service unavailable

The server is currently unable to handle the request due to a temporary overloading or maintenance of the server.

The server has not processed the request. You may resend the request.

If you continue to experience problems, contact PayWay Technical Support. Provide the following information:-

  • your client number
  • the method you sent in the request (e.g. GET, POST)
  • the URL you sent in the request
  • the date/time of the request
  • the response body returned by the server.
Never email your secret API key. Email is not secure.
