Interswitch APIs follow standard HTTP response codes for successful or failed transactions.
| Error | Description |
|---|---|
| 200, 201, or 202 | This means the request was successful, and the action has been carried out. Also note that you will receive a 200, 201, or 202 status code. |
| 400 | A validation error occurred, and the request was not completed. This means a parameter to complete this request is unavailable or invalid in the request payload. |
| 401 | This can be triggered by passing an invalid secret key in the authorization header or in a scenario where there is none. The request will not be authorized as your request does not fulfill the basic requirement for a successful API call. |
| 404 | This means your request could not be fulfilled as the resource/institution requested does not exist. |
| 500, 501,502,503,504 | This request could not be completed due to an error at Interswitch's end. Please report if you encounter any instance of this kind. |
