PayU Hosted Checkout integration for TPV (Third Party Verification) Payment Mode supports both Net Banking (NB) and Unified Payment Interface (UPI) payment methods for subscription-based or autopay payments.

Steps to integrate

1. Create Transaction

Create transaction with beneficiary and SI details for autopay

2. Post Parameters

Post transaction parameters to PayU payment gateway

3. Handle Response

Handle and validate response with reverse hash

Customer journey

The customer journey involves three key steps:

Checkout Initiation: Customer begins the payment process on the merchant's checkout page

PayU Redirect: Customer is redirected to PayU's hosted checkout page for payment completion

Payment Processing: Customer completes the payment using their preferred payment method (Net Banking or UPI)

Step 1: Create Transaction with Beneficiary and SI Details

Create a transaction request with the required beneficiary details and Standing Instruction (SI) parameters for autopay functionality.

Step 2: Post Transaction Parameters

Submit the transaction parameters to PayU's payment gateway using the appropriate environment URL.
