Get Started
Step 1: Access your test account You have to make sure that you get access to a test account, our full test environment that allows you to simulate and process simulation transactions. You can contact merchantsupport-ps@amazon.com to get your test account.
Step 2: Use the correct integration type Before building the integration, you need to make sure that you are selecting and using the proper parameters in the API calls as per the required integration type. All the mandatory parameters are mentioned in every section in the API reference.
Step 3: Create the transaction request Processing a valid API request depends on specifying the right transaction parameters, you need to check the documentation and read every parameter’s range of possible values in order to reduce the errors in processing the transaction.
Step 4: Process the transaction response After each payment is processed, Amazon Payment Services returns the transaction’s response on the URL configured in your account under Technical Settings channel configuration.
You can find more details in the API documentation section Transaction Feedback Implementation.
You need to validate the response parameters returned on this URL by calculating the signature for the response parameters using the SHA Response Phrase configured in your account under Security Settings.
Amazon Payment Services accepts configuring HTTPS URLs only in your Account Technical Settings and for return_url parameter. Amazon Payment Services supports the return_url type to be POST method only under your Technical Settings. Please make sure that your redirection or return_url handles the response as POST Method. For any further support please contact: integration-ps@amazon.com
Step 5: Test and go-live You can use our testing payment card numbers to test your integration and to simulate your test cases. Amazon Payment Services requires that you test your integration before going live to verify the integration and to make sure it is implemented properly.
