Integration security

After receiving a response from PayU, you must calculate the hash again and validate it against the hash that you sent in the request to ensure the transaction is secure. PayU recommends implementing the transaction details APIs and webhook/callback as an extra security measure. For more information on this process, refer to Get Transaction Details API APIs and Webhooks documentation.

You need to ensure that sensitive information related to the integration is not part of the payment request to PayU. The details including — but are not limited to — the following are considered sensitive information:

  • salt value
  • plain text hash string

Along with the request, the sensitive information should not be a part of any merchant-level URL. The following are considered sources for the merchant-level URL:

  • The last web address accessed by a browser before loading PayU’s checkout page.
  • URLs shared as part of payment request to PayU in the parameters: surl, furl, curl, nurl, and termUrl.
  • Notification URLs configured with the merchant account.
  • Invoice Completion URLs configured with the merchant account.

📘

Important

Compare the parameters sent by PayU in the response with the ones you sent in the request to make sure none of them have been changed. You should verify specific parameters such as the transaction ID and amount. PayU is not responsible for any security breaches or loss resulting from your failure to implement the necessary security measures.

Step 2: Verify the payment

PayU recommends this step to reconcile with PayU’s database after you receive the response. Verify the transaction details using the Verification APIs. For API reference, refer to Verify Payment API under API Reference.

📘

Tip

The Transaction ID (txnid) value that you passed in request of Step 1 with PayU must be used here.
