The API is not working or gives an incorrect output, what should I check for?

• Ensure that your implementation handles errors correctly. Refer to the Error Handling section in our documentation.
• If an API call fails, you can look up the returned error code here.
• You can enable debug logging with setDebugLog(). You can find your debug logs in your account page.
• If the above does not help, send us:
  1. Your API implementation.
  2. A minimal HTML document or a link to a web page that we can use to reproduce the issue.
  3. Related debug logs.
