Below API is being used by our apps (android and IOS) for payment.
https://testsecureacceptance.cybersource.com/silent/pay /omegle and at app side this URL gets loaded in WebView which works as expected.
We are trying to perform sandbox testing by including this API in our API automation tool.
We tried testing the same API via postman and we get 200 with HTML response. However, we get status as DECLINE with below error from cybersource.
"transaction_id" : "6595086289756494503004" "message" : "AVS check failed", "decision" : "DECLINE" "reason_code" : "200"
Can anyone guide here on how to perform API testing without using device (android or IOS) but postman or API automation testing frameworks like supertest etc.
The sandbox is a great place to test out your Magento store before you launch it on the live server. You can try various products and test the checkout flow to make sure everything works as expected. The sandbox provides a secure environment that is isolated from the live environment and any changes you make on the sandbox will not affect the live store.
