Why testing matters
Thorough testing helps identify authentication, validation, transaction handling and application errors before customers use your integration.
Test authentication
Confirm that your application securely authenticates with the API and handles invalid credentials without exposing sensitive data.
Test successful requests
Test normal API requests and confirm that your application correctly processes successful responses.
Test failures
Your application should handle rejected requests, validation errors, timeouts and other failures gracefully.
Check transaction handling
Make sure your system does not accidentally create duplicate transactions when requests are retried or when network problems occur.
Production checklist
- Production credentials are stored securely.
- Debugging information is disabled where appropriate.
- Error handling has been tested.
- Logs do not expose sensitive credentials.
- Your application handles API responses correctly.
