Error Overview

Flexiti 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 transaction failed, etc.).
Codes in the 5xx range 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.

403	Forbidden	Request is forbidden for the level of access granted.
404	Not Found	The requested resource doesn't exist.
