Error Overview
Flexiti uses conventional HTTP response codes to indicate the success or failure of an API request. In general:
Codes in the
2xxrange indicate success.Codes in the
4xxrange indicate an error that failed given the information provided (e.g., a required parameter was omitted, a transaction failed, etc.).Codes in the
5xxrange indicates an error with Flexiti's servers.
Some 4xx errors that could be handled programmatically include an error code that briefly explains the error reported.
