You might be generating a unique Order ID or Receipt for every order which can be passed to PayU via


To make your order id to be visible on the PayU dashboard:

  1. In Razorpay's Orders API, use the receipt parameter to send your unique Order ID or Receipt.
  2. Razorpay passes this value to PayU in the udf1 parameter.
  3. Write to your PayU Relationship Manager to show the parameter udf1 in the dashboard and reports as per your use case.

Before routing all traffic or some traffic to a new gateway via Optimizer, the following best practices are recommended:

Live and Test Mode Rules

All rules configured on live or test mode on the Razorpay Dashboard will reflect on live mode. However, credentials added on test mode will not be automatically replicated in live mode.

Sanity Test at Razorpay

You can reach out to Razorpay for basic sanity testing of the integration. Razorpay will try a test payment of small value and ensure that the credentials are correct.

Perform Self Sanity Test

We recommend configuring a rule on live mode to route payments lesser than a set value (for example, ₹2) to the PayU gateway. This helps to test on production whether small value payments are being routed to PayU and working successfully, thus helping to avoid any direct impact on production traffic.

To configure a rule in live mode:

  1. Log in to your .
  2. In the left navigation, click Optimizer.
  3. Click +Add Rule and enter the Rule name and Description.
  4. Click Next and enter the following rule:
    • In Parameter field, select Amount (In Rupees).
    • In Select Connection field, select Less Than.
    • In Enter Amount field, enter the value 2 and click Next.
    Add Rule
  5. Enter the value 100 in the Route field, select PayU in the Payment Via field, and click Next.
    target Provider
  6. Click Publish Rule.

After the integration is tested and successful, you can go live on PayU.
