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.

HTTP Status Code Summary

HTTP Status Codes	Type	Status
200	Success	Everything worked as expected.
401	Unauthorized	An error with the Merchant authentication.
404	Not Found	The requested resource doesn't exist.
409	Bad Request	The request was unacceptable, often due to missing a required parameter or wrong format.
500	Server Errors	Something went wrong on the Flexiti side. (These are rare.)

General Input Errors

Input errors will tend to follow this model:

message: "Some inputs are wrong or missing!"

error: "wrong_inputs"

error_fields:

"param": "parameter_name",

“msg”: “error message”

"value":"parameter_value",

"type":"validation_type",
