⁉️Errors

Tap & Go 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 our servers (these are rare).

Some 4xx errors that could be handled programmatically (e.g., a card is declined) include an error_code that briefly explains the error reported.

Status Code	Message	Reason
200	OK	Everything worked as expected
400	Bad request	The request was unacceptable, often due to missing a required parameter.
401	Unauthorised	No valid API key provided.
500, 502, 503, 504	Server Errors	Something went wrong on our server. (These are rare.)
