Pluxee Card Integration

This section describes the parameters required to collect payments using the Pluxee card with Merchant Hosted Checkout integration (usingΒ _paymentΒ API) with a sample request and response.

πŸ“˜

Note:

Before you use theΒ _paymentΒ API to collect a payment, it is recommended to use the Fetch Balance APIΒ (check_balanceΒ API) to check the Pluxee card balance and display it on the checkout page for the customer.


Steps to Integrate:

  1. Post the payment request to PayU
  2. Check response from PayU
  3. Verify the payment

πŸ‘

Before you begin:

Register for an account with PayU before you start integration. For more information, refer to Register for a Merchant Account.


Sodexo with Merchant Hosted Checkout Integration Workflow

The following describes the characteristics and workflow involved using Merchant Hosted Checkout with Pluxee:

  • The existing _payment API used to initiate payments for online transactions will be used to initiate seamless payments for Pluxee payment option.
  • For Sodexo payment option mode or PG is MC and Ibibo_code or bankcodeis SODEXO.
  • In case customer provides the consent to save the card details with merchant on their check-out page:
    • Merchant should pass save_sodexo_card parameter value as 1 when initiating the transaction using _payment API.
    • After the transaction is processed and successful, for saved card transactions, Sodexo will share the sourceId with PayU and PayU will share this sourceId with merchant in the field3 parameter.

Note: Merchant is not allowed to store the complete card number or card expiry or card CVV details entered by the customer, even if customer provides permission to store the card.

  • Merchant can also initiate transaction using source ID for repeat transactions where customer has provided permission to save the card during the first transaction. In this case, merchant should pass sourceId value in source_id parameter in the _payment API at the time of transaction initiation.
  • In case source_id parameter is passed, PayU will directly initiate the transaction using this sourceId.
  • Merchants are recommended to use the check_balance API for checking the Sodexo card balance. This will provide better experience to customers as available balance can be displayed up-front to customer and can have better SRT as scenarios where balance is less than transaction amount can be stopped at the checkout page itself.

Step 1: Post the payment request to PayU

Customers will select the Pluxee payment option on your website and enter the Pluxee card details and the amount will be based on the goods or services added to the cart.

Hashing

You must hash the request parameters using the following hash logic:

sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||SALT)

For more information, refer to Generate Hash.

Step 2: Check response from PayU

Hash validation logic for payment response (Reverse Hashing)

While sending the response, PayU takes the exact same parameters that were sent in the request (in reverse order) to calculate the hash and returns it to you. You must verify the hash and then mark a transaction as a success or failure. This is to make sure the transaction has not tampered within the response.

The order of the parameters is similar to the following code block:

sha512(SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key)
