How to fix failed API requests

Steps to diagnose and resolve failed requests If your API requests are failing, follow these troubleshooting steps:

1. Check request headers:

   • Ensure that all required headers (e.g., Authorization with a valid API key) are included in the request.
   • Confirm the use of the correct content type, such as application/json for JSON requests.

2. Validate endpoint URLs:

   • Verify that the endpoint URL is accurate and matches the documentation.
   • Ensure the environment (e.g., production or sandbox) matches your intended use.

3. Inspect request payload:

   • Validate the JSON structure and ensure all required fields are included.
   • Use an API testing tool (e.g., Postman) to test the payload manually.

4. Check API version:

   • Confirm that you’re using the correct version of the API, as outdated versions may not support certain features.

5. Monitor response codes:

   • Review the HTTP response codes and messages returned by the API to identify specific issues.

Note: Regularly consult the Signit API documentation for updates and best practices.
