Show PayMe 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. From your server, make a /paymentMethods request specifying:

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.
    • 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).

The /payments response contains:

  • action: Object containing information about the redirect.

    {
"resultCode": "RedirectShopper",
"action": {
    "expiresAt": "2021-01-30T16:09:09Z",
    "paymentMethodType": "payme",
    "url": "https://qr.payme.hsbc.com.hk/...",
    "method": "GET",
    "type": "redirect"
    }
}

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

  1. Pass the action object to your client app. Drop-in needs this to redirect the shopper to the PayMe app.

See the Android Drop-in integration guide to get the payment outcome and show your shopper the result of the payment.
