Dotpay Drop-in integration

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

When making a 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 Web Drop-in integration. The Web 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 payments 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, specify in your /paymentMethods request:

• countryCode: PL
• amount.currency: PLN

Optional Drop-in configuration

When creating an instance of Drop-in, you can also include optional configuration for presenting the list of issuing banks.

   const dropin = checkout
     .create('dropin', {
       paymentMethodsConfiguration: {
         dotpay: { // Optional configuration for Dotpay
             showImage: false, // Optional. Set to **false** to remove the bank logos from the Dotpay form.
             issuer: "92" // // Optional. Set this to an **id** of a Dotpay issuer to preselect it.
         }
       }
     })
     .mount('#dropin');

Make a payment

When the shopper selects the Pay button, Drop-in calls the onSubmit event, which contains a state.data.

1. Pass the state.data to your server.

2. From your server, make a /payments request, specifying:
   • paymentMethod: The state.data.paymentMethod from the onSubmit 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. This URL can have a maximum of 1024 characters.

The /payments response contains:

• 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, you also need the following from the /payments response:

• action.paymentData: Store this on your server — this is 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.

{
 "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 front end. Drop-in needs the action object to redirect the shopper to the issuing bank's website.

Handle the redirect result

Drop-in usesdropin.handleAction(action) to redirect the shopper to the issuing bank's website. After the shopper is redirected back to your website, check the payment result:

• From your server, make a POST /payments/details request, specifying:
  • details: Object that contains the URL-decoded values of the parameters that were returned when the shopper was redirected back to your site. 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

  {
        "details":{
          "{hint:Verify the parameters from /payments response}payload{/hint}":"Ab02b4c0!BQABAgCW5sxB4e/=="
        }
  }

  The /payments/details response contains:
  • resultCode: Use this to present the 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 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.

Before you can accept live Dotpay payments, you need to submit a request for Dotpay in your live Customer Area.
