African eWallets and eBanking for API only

Add African eWallets and eBanking to an existing API integration.

Accept African eWallets and eBanking payments using our APIs, and build your own payment form to have full control over the look and feel of your checkout page.

Before you begin

These instructions explain how to add African eWallets and eBanking to your existing API-only integration. The API-only integration works the same way for all payment methods. If you haven't done this integration yet, refer to our API-only integration guide.

Before starting your African eWallets and eBanking integration:

  1. Make sure that you have set up your back end implementation.
  2. Add African eWallets and eBanking in your Customer Area.

When building your integration, note that you can already collect optional parameters from the shopper. This enhances the shopper experience as they won't have to fill these in later when they're redirected to the Celullant payment form.

African shoppers expect merchant's email and direct phone number for requesting refunds and cancellations on the payment form. Take this into account when building your payment form for African eWallets and eBanking.

The /payments response contains:

  • action.url: Link to where you should redirect your shopper.
  • action.method: GET or POST. The HTTP request method that you should use. After the shopper completes the payment, they will be redirected back to your returnURL using the same method.
    The redirect method depends on your payment method configuration and the length of the data included in the request, so make sure that your integration can handle both HTTP GET and HTTP POST methods.

To verify the payment result in the next step, you also need the following from the /payments response:

  • action.paymentData: The paymentData value that you send in your /payments/details request.
  • details: Array of parameters that you need to send in your /payments/details request. For example, payload or redirectResult.
    The parameters can vary based on the payment method configuration. Always check the details array for the parameters that you need to send in your next API request.
/payments response
      "url": ""


Handle the redirect

  1. To complete the payment, redirect the shopper to the action.url returned in the /payments response.
    When using the HTTP GET method:
    For security reasons, when displaying the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView.
  2. After the shopper is redirected back to your website or app, check the payment result by making a /payments/details request, specifying:
    • paymentData: Value you received in the /payments response.
    • details: Object that contains the URL-decoded values of the parameters that were returned when the shopper was redirected back to your website or app. For example, payload or redirectResult.
    The parameters can vary based on the payment method configuration. To check which parameters you should submit, always check the details array from the /payments response.
    /payments/details request
           "{hint:Verify the parameters from /payments response}payload{/hint}":"Ab02b4c0!BQABAgCW5sxB4e/=="
    You receive a response containing:
    • resultCode: Use this to present the result to your shopper.
    • pspReference: Our unique identifier for the transaction.
    /payments/details response
       "resultCode": "Authorised",
       "pspReference": "88154795347618C"

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

You will receive the funds in 7 days.
Cancelled The shopper canceled the payment while on the website. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.

Refused The payment was refused by the shopper's bank. Ask the shopper to try the payment again using a different payment method.

If the shopper failed to return to your website or app, wait for notification webhooks to know the outcome of the payment. The notification webhooks you can receive for are:

eventCode success field Description Action to take
AUTHORISATION false The transaction failed. Cancel the order and inform the shopper that the payment failed.
