PayNow iOS Component

Our PayNow Component renders PayNow in your payment form.

Requirements

Select the server-side flow that your integration uses:

Show PayNow in your payment form

Include PayNow in the list of available payment methods.

1. Specify in your /paymentMethods request:

   • countryCode: SG
   • amount.currency: SGD
   • channel: Specify iOS

2. Decode the /paymentMethods response with the PaymentMethods structure.

   let paymentMethods = try JSONDecoder().decode(PaymentMethods.self, from: paymentMethodsResponse)

   Find paymentMethods.type paynow and put it into an object. For example, paynowPaymentMethod.

3. Create an instance of APIContext with the following parameters:

   Parameter name	Required	Description
   clientKey		Your client key.
   environment		Use test. When you are ready to accept live payments, change the value to one of our live environments.

4. Initialize the PayNow Component:

   let paynowComponent = paynowComponent(paymentMethod: paynowPaymentMethod, apiContext: apiContext)
   paynowComponent.delegate = self
   // In this example, the Pay button will show 10 SGD.
   // The value is in minor units. Change the currencyCode to the currency for the PayNow Component.
   paynowComponent.payment = Payment(amount: Amount(value: 1000,
                                                                 currencyCode: "SGD"))
   present(paynowComponent.viewController, animated: true)

Make a payment

When the shopper proceeds to pay, the Component invokes the didSubmit method containing the data.paymentMethod from the PaymentComponentDelegate.

1. Pass the data.paymentMethod to your server.

2. From your server, make a /payments request, specifying paymentMethod.type: the data.paymentMethod from your client app.

   The response contains the following data:

   • resultCode: Pending
   • action: Contains the QR code qrCodeData.

Show the QR code

Use the information in the action object of the /payments response to render the QR code:

• action.qrCodeData: Use this to render the QR code on your checkout page.

The shopper can either scan the QR code, or take a screenshot of the QR code and upload it to their bank app.

Test and go live

Before you can accept live payments, you must contact our Support Team to add PayNow in your live Customer Area.

You can penny test PayNow payments in your live Customer Area, using small amounts and a real banking app to scan a test QR.

You can check the status of PayNow payments in your live Customer Area > Transactions > Payments.
