Calculating…
Who uses it, and for what
A node failed with 422: find out it is a validation error and which field to check.
Decide which errors to retry automatically and which should alert a person.
Understand API errors without reading the HTTP specification.
How this tool works
Plain-language meaning
Each code is explained in terms of what went wrong in your workflow.
A concrete fix
What to change in the node, the credential or the data.
Retry or not
Temporary errors (408, 429, 5xx) should be retried with backoff; others need a fix first.
Frequently asked questions
Should I retry every failed request?
No. Retrying a 400 or 401 repeats the same failure. Retry only timeouts, rate limits and server errors, with increasing delays.
What is the difference between 401 and 403?
401: the API does not know who you are (missing or expired credentials). 403: it knows you, but you are not allowed to do this.
Where is the real error message?
In the response body. In n8n, enable "Include response headers and status" or "Never error" to inspect it.
