Test Your Set Up

You can send a test API request to validate that your account, API key, JWT messages, and MLE security are working as intended.
Visa Acceptance Solutions
Visa Acceptance Platform
 recommends that you test and verify that your payment system can securely send and receive REST API messages before transitioning to a production account.
Postman Testing
You can verify your HTTP signature message using Postman. To download a Postman collection of basic payment API requests, see the Cybersource REST API collection on the Postman website.
When testing an API outside of the Developer Center's API Reference sandbox, send your test API requests to the test server:
https://apitest.visaacceptance.com
For example, to test an authorization request, you can send the request to this endpoint:
https://apitest.visaacceptance.com
/pts/v2/payments

Test Your API Response MLE Key

Follow these steps to verify that your API response MLE key is working using the API Reference in the Developer Center. If you have not already created or submitted an API response MLE certificate, see Create or Submit an API Response MLE Key.

      This is the key ID that you saved in Step 10 in the Create or Submit an API Response MLE Key section in Enable Message-Level Encryption.
    • Response decryption:
       Click
      Browse
       to submit your own decryption private key from your local system. Only
