Question: What is the most common cause of a 404 error?
- The data has been migrated to a new server.
- Your access token is outdated.
- You have an improperly scoped authentication method.
- The data is either deleted or archived.
Explanation
A 404 Not Found response usually means the requested record or resource cannot be found. In HubSpot, this can happen when the record has been deleted, archived, or the requested ID no longer points to an active resource. The API call may be correctly authenticated, but the target data is unavailable. This makes it different from scope or token issues, which normally produce authorization-related errors. Checking whether the record exists and whether archived records are being requested helps troubleshoot the issue.
Why the other options are incorrect
Migrated to a new server This is incorrect because migration-related issues use different error handling and are not the most common 404 cause.
Outdated access token This is incorrect because expired or invalid tokens usually cause authentication errors, not 404 errors.
Improperly scoped authentication This is incorrect because missing scopes usually cause permission errors, not missing-resource errors.
