About Errors

Check the errors returned in the API responses from Curlec.


Curlec APIs, when fired, can have either a successful response or a failure response. All successful Curlec API responses return with HTTP Status code 200. In case of failure, a JSON error response is returned with the relevant error parameters.

This error response helps to:

  • Map and analyse top failure reasons.
  • Identify the source of failure. It can be due to customer action or external factors (Curlec, Gateway, Bank or Network).
  • Identify the payment step and the exact failure reason. Display valid responses and provide meaningful next steps to your customers.

The error response contains code, description, field, source, step, reason and metadata parameters that help diagnose and solve the error.

In this sample code, see the description, source, step and reason, indicating that the API failed due to authentication failure for incorrect OTP.

You can notify your customer and ask them to retry the payment with the correct OTP at Curlec Checkout.
