Error codes for single card payments

Learn how to manage different types of error messages received during transactions for each payment method.

What types of response codes does Kushki return?

Kushki will return two different response codes to indicate the success or failure of a transaction: processorError and code. The code field returns generic messages. On the other side, the field processorError indicates that the transaction has passed through the processor and has probably been mapped by Kushki in order to provide a specific explanation of the reason why your transaction could not be completed.

Codes returned by Kushki for one-time card payments

Kushki’s API will perform validations before sending a transaction to the processors. If this is the case, the processorError field will not appear in the response and you will only see the code field. An example of a message returned by Kushki’s API is shown below:

{"message": "ID de comercio o credencial no válido",
"code": "K004" }

In the table below, generic error codes returned through the code field are summarized.
