A developer is working on an ecommerce platform that communicates with several third-party payment processing APIs The third-party payment services do not provide a test environment.

The developer needs to validate the ecommerce platform's integration with the third-party payment processing APIs. The developer must test the API integration code without invoking the third-party payment processing APIs.

Which solution will meet these requirements'?

Answers
D.
Set up an Amazon API Gateway REST API for each third-party API Specify an integration request type of Mock Configure integration responses by using sample responses captured from the real third-party API
Suggested answer: D

Explanation:

Mocking API Responses:API Gateway's Mock integration type enables simulating API behavior without invoking backend services.

Testing with Sample Data:Using captured responses from the real third-party API ensures realistic testing of the integration code.

Focus on Integration Logic:This solution allows the developer to isolate and test the application's interaction with the payment APIs, even without a test environment from the third-party providers.
