Errors

Instafill uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.). Codes in the 5xx range indicate an error with Instafill’s servers (these are rare).

Status Code	Description	Explanation
200	OK	Everything worked as expected.
401	Unauthorized	No valid API key provided.
403	Forbidden	The API key doesn’t have permissions to perform the request.
404	Not Found	The requested resource doesn’t exist.
415	Unsupported Content Type	The content type of the request is not supported.
500, 503	Server Errors	Something went wrong on Instafill's end. (These are rare.)
