Paytm Drop-in integration

Our Web Drop-in renders Paytm in your payment form, and redirects the shopper to Paytm to complete the payment.

When making a Paytm 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 Paytm 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 Paytm integration:

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

Show Paytm 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 Paytm in your payment form, specify in your /paymentMethods request:

• countryCode: IN
• amount.currency: INR

Make a payment

When the shopper selects to pay, 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.
   • shopperReference(optional) : Your unique identifier for the shopper (minimum length three characters).

     For improved conversion rates, we recommend that you pass the shopperReference.

   The /payments response contains an action object with the information needed to redirect the shopper.
   

   https://docs.adyen.com/payment-methods/afterpaytouch/ios-drop-in#-payments-response

   /payments response

   {
   "resultCode":"RedirectShopper",
   "action":{
     "paymentMethodType":"paytm",
     "method":"GET",
     "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
     "type":"redirect"
   }
   }
3. Pass the action object to your front end.

Handle the redirect result

Handling the redirect works the same way for all redirect payment methods.

Drop-in uses dropin.handleAction(action) to redirect the shopper to complete the payment. After the shopper is redirected back to your website:

1. URL-decode the redirectResult that was appended to your returnUrl when the shopper was redirected back to your site, and pass it to your back end.
2. Check the payment result by making a POST /payments/details request, specifying:
   • details: Object that contains the URL-decoded values of the parameters that were appended to the returnUrl when the shopper was redirected back to your site.
   https://docs.adyen.com/payment-methods/afterpaytouch/web-drop-in#-payments-details-request

   /payments/details request

   curl https://checkout-test.adyen.com/v67/payments/details \
   -H "x-API-key: YOUR_X-API-KEY" \
   -H "content-type: application/json" \
   -d '{
       "details": {
         "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
     }
   }'

   The /payments/details response contains:
   • resultCode: Use this to present the payment result to your shopper.
   • pspReference: Our unique identifier for the transaction.
   https://docs.adyen.com/payment-methods/afterpaytouch/web-drop-in#-payments-details-response

   /payments/details response

   {
    "resultCode": "Authorised",
    "pspReference": "88154795347618C"
   }

Present the payment result

Use the resultCode that you received the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for Paytm are:

If the shopper failed to return to your website or app, wait for notification webhooks to know the outcome of the payment:

Test and go live

Before you go live, test your integration using the following credentials:

Check the status of Paytm test payments in your Customer Area > Transactions > Payments.

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