Errors

What an error response looks like and what each status means.

An error the API returns is a JSON object with a message and a code. Handle errors by HTTP status.

{
  "message": "Unauthorized",
  "code": "UNAUTHORIZED"
}

Status	Meaning
400	A parameter is invalid, with each problem listed in an issues array. A paging cursor that was refused also returns 400, and the message says why.
401	The key is missing, unknown, revoked, or does not hold the claim the route needs.
404	The route does not exist, or the record does not exist for your business or cannot be read on its own, such as a bank fee.
405	The request used a method other than GET or HEAD.
500	Something failed on our side. Retry.
