Dotpay Drop-in integration

Our iOS Drop-in renders Dotpay in your payment form, and redirects the shopper to their selected bank's website or app to complete the payment.

When making an Dotpay payment, you additionally need to:

• Handle the redirect result after the shopper returns to your website.

Before you begin

This page explains how to add Dotpay to your existing iOS Drop-in integration. The iOS Drop-in integration works the same way for all payment methods. If you haven't done this integration yet, refer to our Drop-in integration guide.

Before starting your Dotpay integration:

1. Make sure that you have set up your back end implementation, and added Drop-in to your payment form.
2. Add Dotpay in your test Customer Area.

Show Dotpay 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 Dotpay in your payment form, you need to specify in your /paymentMethods request:

• countryCode: PL
• amount.currency: PLN

After the shopper selects a payment method and provides payment details, Drop-in invokes the didSubmit method which contains data.paymentMethod. Pass data.paymentMethod to your server and make a payment request.

Make a payment

When the shopper proceeds to pay, Drop-in invokes the didSubmit method which contains data.paymentMethod.

1. Pass data.paymentMethod to your server.
2. From your server, make a /payments, specifying:
   • paymentMethod: The state.data.paymentMethod from the onChange event from your front end.
   • reference: Your unique reference for this payment.
   • amount: The amount that the shopper needs to pay.
   • returnUrl: The URL the shopper will be redirected back to after they complete the payment.

{
  "amount": {
   "currency": "PLN",
   "value": 1000
  },
  "reference": "YOUR_ORDER_NUMBER",
  "paymentMethod": {
   "type": "dotpay",
   "issuer": "92"
  },
  "returnUrl": "http://my.url.com/done",
  "merchantAccount": "YOUR_MERCHANT_ACCOUNT"
}

The /payments response contains:

• action: Object containing information about the redirect.

{
 "resultCode": "RedirectShopper",
 "action": {
     "data": {},
     "method": "GET",
     "paymentData": "Ab02b4c0!BQA...",
     "paymentMethodType": "dotpay",
     "type": "redirect",
     "url": "https://test.adyen.com/hpp/skipDetails.shtml?brandCode=dotpay&currencyCode=PLN..."
 },
 "details": [
     {
         "key": "payload",
         "type": "text"
     }
 ],
 "paymentData": "Ab02b4c0!BQA...",
 "redirect": {
     "method": "GET",
     "url": "https://test.adyen.com/hpp/skipDetails.shtml?brandCode=dotpay&currencyCode=PLN..."
 }
}

3. Pass the action object to your client app. Drop-in needs this to redirect the shopper to the issuing bank's website or app.

Handle the redirect result

Drop-in redirects the shopper to the issuing bank's app or website where they complete the payment. However, you need to inform Drop-in when the shopper returns to your app. To do this, implement the following in your UIApplicationDelegate:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any] = [:]) -> Bool {
   RedirectComponent.applicationDidOpen(from: url)

   return true
}

After the shopper is redirected back to your app, check the payment result by making a /payments/details request.

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 Dotpay are:

Test and go live

Before accepting live Dotpay online banking payments, test your integration using test.adyen.com endpoints in your test environment.
Once you send a test payments request, you'll be redirected to Dotpay. You need to enter your name and email in order to receive confirmation from Dotpay. You don't need any specific test credentials to do test payments.
Check the status of Dotpay test payments in your Customer Area > Transactions > Payments.
