Errors

Errors return the HTTP status code and a JSON body with statusCode, error (the short label) and message (a human-readable detail).

{
  "statusCode": 429,
  "error": "Too Many Requests",
  "message": "Too many requests to unified.to API; max requests per minute: N"
}

Status	Error	Meaning
`400`	Bad Request	The request was malformed or failed validation.
`401`	Unauthorized	The connection is likely broken; re-authorize it.
`403`	Forbidden	The connection is missing permissions or scopes.
`404`	Not Found	The requested resource does not exist.
`429`	Too Many Requests	Rate limit exceeded (see the two sources below).
`500`	Internal Server Error	An unexpected error occurred.
`501`	Not Implemented	Not supported by this integration.

Errors from the underlying integration pass through: the integration's status comes back as ours (429, 401, 403, 404 or 5xx), usually with its message. When the integration's error body is unclear, Unified extracts what it can and returns a clearer message.

429 Too Many Requests

A 429 has two possible sources:

The integration's own rate limit, passed through.
Unified's workspace limit: a rolling 60 seconds, set by plan, with the message Too many requests to unified.to API; max requests per minute: N.
