Integrate Turbo UPI TPV

This is a mandatory step to confirm the authenticity of the details returned to the Checkout form for successful payments.

To verify the razorpay_signature returned to you by the Checkout form:

1. Create a signature in your server using the following attributes:

   • order_id: Retrieve the order_id from your server. Do not use the razorpay_order_id returned by Checkout.
   • razorpay_payment_id: Returned by Checkout.
   • key_secret: Available in your server. The key_secret that was generated from the
     Curlec Dashboard
     .

2. Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a HMAC hex digest as shown below:

   HMAC Hex Digest

   copy

   generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);
   
   if (generated_signature == razorpay_signature) {
       payment is successful
   }

3. If the signature you generate on your server matches the razorpay_signature returned to you by the Checkout form, the payment received is from an authentic source.

The SDK manages the linked UpiAccounts on the application by triggering manageUpiAccounts(), which follows the following internal non-transaction flows for UpiAccounts:

• Fetch balance: Check the customer's account balance.
• Change UPI PIN: Provide the customer the ability to change their UPI PIN.
• Reset UPI PIN: Let your customers reset the PIN for their account.
• Delete the account from the application: Let your customers delink, that is, remove a selected UPI account from your application.

if (checkout.upiTurbo != null) {
    checkout.upiTurbo.manageUpiAccounts("9000090000","#000000"/*color - in hex format(nullable)*/, new GenericPluginCallback() {
        @Override
        public void onSuccess(@NonNull Object data) {
            /* can be safely ignored */
        }

        @Override
        public void onError(@NonNull JSONObject error) {
            /* Throws error if Turbo UPI cannot be initialized or throws error */
        }
    });
