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.

  1. Pass the to your server.

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

  "amount": {
   "currency": "PLN",
   "value": 1000
  "reference": "YOUR_ORDER_NUMBER",
  "paymentMethod": {
   "type": "dotpay",
   "issuer": "92"
  "returnUrl": "",
  "merchantAccount": "YOUR_MERCHANT_ACCOUNT"

The /payments response contains:

  • resultCode: RedirectShopper
  • details: Array that contains the key parameter name and the corresponding data type that you should expect when the shopper is redirected to your returnURL. You need to submit this value in your /payments/details request when handling the redirect result.
  • action: Object containing information about the redirect.
  • action.paymentData: Value that you need to submit in your /payments/details request when handling the redirect result.
  • 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.

     "data": {},
     "method": "GET",

  1. 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 uses the action object to redirect the shopper to the issuing bank's website. After the shopper is redirected back to your website, you need to check the payment result by making a /payments/details request.

For more information and detailed instructions, refer to Handling the redirect result.

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:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment has been successful.
You will receive the funds in 2-3 days.
Cancelled The shopper cancelled the payment while on their bank's website. Ask the shopper whether they want to continue with the order, or request that they select a different payment method.
Pending The shopper has completed the payment but the final result is not yet known. It may take minutes or hours for the Dotpay payments network to confirm this. Inform the shopper that you've received their order, and are waiting for the payment to be completed.
You will receive the final result of the payment in an AUTHORISATION notification.
Refused The payment was refused by the shopper's bank. Ask the shopper to try the payment again using a different payment method.
If a shopper completed the payment but failed to return to your website or app, you will receive the outcome of the payment in an AUTHORISATION notification.

Test and go live

Before accepting live Dotpay online banking payments, test your integration using 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.
