Error Handling

The DusuPay API uses HTTP status codes to indicate the success or failure of the API requests. The section describes the summary of these codes and what they mean in our context.


  • Codes in the 2XX range mean that the API request was processed successfully.

  • Codes in the 4XX range mean that something was wrong with the data that you sent. For example, you might have missed some required parameters/headers, or you might be using the wrong API credentials.

  • Codes in the 5XX range indicate an error in processing on our end
