Test Your Setup

You can send a test API request to validate that your account, API key, JWT messages, and MLE security are working as intended.
Cybersource
 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 use Postman to verify your HTTP signature message. To download a Postman collection of basic payment API requests, see the 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.cybersource.com
For example, to test an authorization request, you can send the request to this endpoint:
https://apitest.cybersource.com
/pts/v2/payments

Test Your REST–API Response Key

Follow these steps to verify that your API response MLE key is working. If you have not already created or submitted an API response MLE certificate, see the Create or Submit a REST—API Response MLE Key section in Enable Message-Level Encryption.
  1. Go to the REST API Reference page in the
    Cybersource
     Developer Center:
  2. On the left navigation panel, choose an API that supports MLE. For testing purposes, you can choose
    Intelligent Commerce > Intelligent Commerce Product > Enroll a Card
    .
    MLE support is indicated by
    Request MLE
     and
    Response MLE
     at the top of the screen.
  3. Choose the
    MLE Configuration
     tab.
  4. In the Message Level Encryption Credentials section, enter your API response MLE key credentials:
    • Response encryption:
       Enter the key ID of your API response MLE key.
      You saved this key ID 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 private decryption key from your local system. Only
      .p12
       files are supported.
  5. Click
    Update Credentials
    .
  6. From the
    Send
     drop-down menu, choose
    Send Request with Message Level Encryption
    .
  7. Click
    Send
    .
  8. When a
    Success: HTTP Status Code: 201
     message displays in the Response section, your API response key is properly configured.
