How do you test an Integration Procedure that calls an external API?

• A. Test by running in production only.
• B. Use a mock endpoint or a sandbox environment, verify input/output mappings, and review logs for errors.
• C. Testing is not possible for external APIs.
• D. Only check the response time.

Answer: (B)

Testing an Integration Procedure that calls an external API is about validating the whole flow while avoiding live side effects. The best approach is to use a mock endpoint or a sandbox environment so the IP calls a controlled API rather than the real production service. This lets you verify that input mappings produce the correct request payload, that the output mappings correctly translate the API’s response back into your data structure, and that any errors are surfaced and handled as expected. Reviewing logs for errors, timeouts, and malformed responses is crucial because it shows where the integration may fail in real operation. It’s also important to test different scenarios: success responses, error codes, authentication failures, and network issues. Other options miss essential parts: testing only in production risks data changes and outages, claiming testing isn’t possible for external APIs is incorrect since mocks and sandboxes enable safe testing, and focusing only on response time ignores data transformation and error handling.
