Question: What is the best strategy to avoid receiving 400-level errors?
- Routinely clean your account data.
- Rotate your access tokens every 60 days.
- Ensure your integration has the correct scopes.
- Ensure your integration has the correct access token.
Explanation
A 400-level error often happens when the request contains invalid formatting, missing required values, or data that does not match the expected field rules. Clean account data reduces validation problems before an integration sends records through the API. HubSpot object APIs can return 400 Bad Request when submitted values are invalid. This is different from authentication or permission errors, which usually involve credentials or scopes. Good data hygiene helps prevent avoidable request failures at the source.
Why the other options are incorrect
Access tokens This is incorrect because token rotation does not fix invalid data or malformed request values.
Scopes This is incorrect because missing scopes are more closely tied to permission errors, not data validation errors.
Correct access token This is incorrect because a valid token confirms access, but it does not correct bad request data.
