      • Enable UPI Intent.
    • Cards as a payment method
      • Enable the method cards.

  4. If you wish to send PayU's offer ID to the downstream gateway, you can use Optimizer's Custom Identifier 1 to map PayU’s Offer key. This will help you send offer keys to PayU for processing and reconciliation.

Before you go live with PayU on Optimizer, disable the retry option.

Retry Disablement

PayU attempts a retry on the PayU checkout page by default. This needs to be disabled while using PayU via Optimizer as all payments need to be routed through Razorpay and its checkout. If retry is enabled, Razorpay will not know about the status of the payment, and it may lead to breakages.

Consider the following points:

  1. The retry disablement option can only be done in one go for all methods as PayU cannot disable retry at a method level.
  2. If you have an existing integration with PayU, disabling retry might partially affect the success rate. Follow the steps given below to avoid any implications:
    • Disable the retry option before the traffic goes live on Optimizer and plan a quick switch-over once testing is completed.
    • Create a new account on PayU side to limit the impact on existing integrations for you and PayU.
    • Get all the configurations done except for retry disablement and ask PayU to disable retry just before you go live.

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.

Follow the steps given below 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.
    Publish Rule

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