Scenario 4. Purchase with confirmation via a code sent in a message

When performing a purchase, the customer uses a code the mobile network operator sends them to confirm the payment.

Countries and regions Burkina Faso, Democratic Republic of the Congo, Côte d'Ivoire, Cameroon, Ghana, Mali, Rwanda, Senegal
Payment currencies CDF, GHS, RWF, XAF, XOF
Payment amount limits Contact your key account manager at Monetix for details. Also you can check the payment amount limits in your project by using Dashboard.
Payment processing time Contact your key account manager at Monetix for details.
Currency conversion On the Monetix side
Refund
Onboarding and access fee Contact your key account manager at Monetix for details.
Special considerations

The amounts for the RWF, XAF, XOF currency must be specified in major currency units (without any fractional part) according to the ISO-4217 alpha-3 standard.

For example, if the customer initiates a 1000 RWF purchase in your system, you are required to submit the 1000 as the payment amount in your purchase request.

You can check the number of digits for minor currency units for any currency in Currency codes.

Here is an example of the data from the request with the OTP:

Figure 7. Example of the data from a request with the OTP
{
    "general": {
        "project_id": 1234,
        "payment_id": "payment_47",

        "additional_data": {
            "approval_code": "123456"
        }
    }
}

For the mobile network operator to confirm the payment on time, it is recommended to send a request with the OTP within 80 or 90 seconds after you've received a callback notifying that you're required to submit the OTP your customer's received (contact your key account manager at Monetix to get the OTP expiry time relevant in your case).

After the request is sent, the payment processing may continue as follows:

  • If the OTP is correct and sent on time, the payment processing continues on the side of the payment platform, provider service, and mobile network operator service. You will receive a final callback with the payment result after the payment processing is complete.
  • If the OTP is sent on time but is incorrect, the payment platform resends your system a callback notifying that you're required to submit the OTP. In this case you should provide the customer with an opportunity to specify the correct OTP once more and send a request with this OTP to the payment platform (also within 80 or 90 seconds).

If the OTP is sent after 80 or 90 seconds, the following options are possible:

  • If the OTP is correct and sent on time to be processed by the mobile network operator, the payment processing continues on the side of the payment platform, provider service, and mobile network operator service. You will receive a final callback with the payment result after the payment processing is complete.
  • If the OTP is incorrect or expired, the payment platform resends your system a callback notifying that you're required to submit the OTP. In this case it is recommended that you send the payment platform a request for sending a new OTP to the customer, then receive the new OTP from the customer, and send it in a request to the payment platform.

Callback

In the Mobile Commerce in Africa payment method, the payment platform returns the purchase result in a callback. For the information about the callback structure, see Callbacks in Gate.

In this payment method, callbacks also have the account object with the number and type parameters containing information about the customer's phone number and their mobile network operator.

The following is an example of a callback body with the information about a successfully completed purchase.
