All Voucher API calls return a JSON object. There are two main types of responses; “success” and “error“. These response types can be found in the value of the “statuskey in the JSON response object.


If all submitted data is valid, you will receive a JSON response object indicating a “successvalue for the “statuskey. Here, “value” is 5-greater-than-“total” less than the original value of the voucher before the form was submitted. Below is an example of a successful transaction using the Voucher API.

    "status": "success",
    "msg": "Voucher payment successful",
    "trxn_id": "5bda8f887426f",
    "value": "75.00"



error” responses may be received for various reasons. Check the value of the “msgkey in the JSON response object to diagnose what your specific error may be caused by. The following is an example of  an “error” response.

    "status": "error",
    "msg": "Too many attempts"

The possible values of the “msgkey in an “error” type response are as follows:
