Charge Cards

Monnify allows you to charge your customers who make one-time payments through the use of their cards. To charge a card you will need to make a request to the endpoint below:

This endpoint is protected with OAuth 2.0 Bearer token. To find out more about authorization for Monnify endpoints, check Here

Endpoint URL: {{base_url}}/api/v1/merchant/cards/charge

HTTP Method: POST

The {{base_url}} for test is https://sandbox.monnify.com but when you go live, it changes to the live url

Sample Request Body

{
    "transactionReference": "MNFY|20190514172736|000001",
    "collectionChannel": "API_NOTIFICATION",
    "card": {
        "number": "4111111111111111",
        "expiryMonth": "10",
        "expiryYear": "2022",
        "pin": "1234",
        "cvv": "122"
    },
    "deviceInformation": {
        "httpBrowserLanguage":"en-US",
        "httpBrowserJavaEnabled":false,
        "httpBrowserJavaScriptEnabled":true,
        "httpBrowserColorDepth":24,

   }
}

The response that will be gotten depends on the kind of card used for the transaction. There are cards charged with the use of an OTP, without an OTP, and also with 3DS Secure Authentication. See sample response for each scenario. An extra mandatory object parameter(deviceInformation) is required to capture the user’s device information.

Sample Response (For 3DS Secure Authentication)

Frontend posts an Html form that redirects to the VISA card website to collect OTP sent to the user’s phone. After the OTP verification is completed on the VISA card endpoint, it makes a post request to the callback URL, which is similar to what is given in the TermUrl(It’s also possible to replace the TermUrl with your own URL so as to know when OTP verification process ends).

Finally, to authorize the charge on the user’s card, you make an authenticated post request (containing your transaction reference, collection channel, api key, and card details) to the authorized endpoint. Check 3DS Secure Authentication on how to authorize the charge.
