Deprecating September 2026: HTTP Signature Messaging
Test Your Setup
You can send a test API request to validate that your account, API key, HTTP headers, and
HTTP message body 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. Use the test examples provided in this section to
test your set up. You should also test any additional API requests that you will use in
your live environment.
