KNET Drop-in integration

Add KNET to an existing Drop-in integration.

If you are using Android Drop-in v5.0.0 or later:

This payment method requires no additional configuration.

Follow the Drop-in integration guide.

Our Android Drop-in renders KNET in your payment form, and redirects the shopper to the KNET app or website where they can complete the payment.

Requirements

Requirement Description
Integration type Make sure that you have built an Advanced flow Android Drop-in integration.
Setup steps Before you begin, add KNET in your Customer Area.

Show KNET in your payment form

Drop-in uses the countryCode and the amount.currency from your /paymentMethods request to show the available payment methods to your shopper.

To show KNET in your payment form, specify in your /paymentMethods request:

Make a payment

When the shopper proceeds to pay, Drop-in returns the paymentComponentData.paymentMethod.

  1. Pass the paymentComponentData.paymentMethod to your server.

  2. From your server, make a /payments request, specifying:

    • paymentMethod: The paymentComponentData.paymentMethod from your client app.
    • shopperName: The shopper's full name.
    • shopperEmail: The shopper's email address.
    • telephoneNumber: The shopper's telephone number.
    • returnUrl: URL to where the shopper should be redirected back to after they complete the payment. Get this URL from the Component in the RedirectComponent.getReturnUrl(context).

In the /payments response, note the action object. This contains the information needed to redirect the shopper.

If your integration is set up correctly, the action object is passed from your server to the client.

Check the payment result

Drop-in redirects the shopper to complete the payment. When the shopper returns back to your app, Drop-in provides the actionComponentData object.

From your server, make a POST /payments/details request providing:

  • details: The actionComponentData.details object from Drop-in.

You receive a response containing:

  • resultCode: Use this to present the payment result to your shopper.
  • pspReference: Our unique identifier for the transaction.

Present the payment result

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

The resultCode values you can receive for KNET are:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment has been successful.
Cancelled The shopper cancelled the payment while on KNET's website. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error There was an error when the payment was being processed. Inform the shopper that there was an error processing their payment. The response contains a refusalReason, indicating the cause of the error.
Pending or
Received		 The shopper has completed the payment but the final result is not yet known. Inform the shopper that you have received their order, and are waiting for the payment to be completed.

To know the final result of the payment, wait for the AUTHORISATION webhook.
Refused The payment was refused by the KNET. Ask the shopper to try the payment again using a different payment method.

If the shopper closed the browser and failed to return to your website, wait for webhooks to know the outcome of the payment. The webhooks you can receive for KNET are:

eventCode success field Description Action to take
AUTHORISATION false The transaction failed. Cancel the order and inform the shopper that the payment failed.
AUTHORISATION true The shopper successfully completed the payment. Inform the shopper that the payment has been successful and proceed with the order.
