Merchant Hosted Checkout

Custom Checkout or Merchant Hosted Checkout integration is used to process credit/debit card payments on your website using PayU, collect card details on your website and submit them to PayU via API. This eliminates the need for redirection to PayU’s payment page, resulting in a more secure and efficient transaction.

👍

Before you Begin:

• PayU strongly recommends you test your integration using the test merchant Key or Salt. To create a test merchant account, refer to Register for a Merchant Account on Dashboard. After you create a test merchant account, you can access the test Key or Salt as described in Generate Merchant Key and Salt on PayU Dashboard.
• PayU recommends you to integrate with Test environment initially. For merchants registered before August 3rd, 2023, use the following URL to sign up for the Test environment:

• Later, register for a production account with PayU before you start integration. For more information, refer to Register for a Merchant Account.

Workflow

The following process diagram illustrates the Merchant Hosted Checkout workflow:

1. It operates through a form post-call directly from the customer’s browser, sending their payment data into the PayU’s systems.
2. A payment process initiated from your e-commerce website travels through the PayU’s secured environment before reaching the card ACS or a bank’s Net Banking page.
3. After the transaction is completed in the bank’s website environment, the customer is redirected to your website.

Customer Experience

Step 1: The customer completes shopping at your website and initiates a transaction with saved card (for example, VISA) credentials.

Step 2: The customer enters the CVV and proceeds to complete the payment.

Step 3: After the credentials are entered, and the payment flow is launched, the user is navigated through a secured PayU environment that reflects the transaction ID.

Step 4: The flow takes the user to the login ACS page of the bank, where the user needs to complete the transaction by using the OTP sent by the bank to the registered mobile number.

Step 5: Customer is shown the status (failed/successful) on your website based on the transaction status from PayU.
