Before routing any 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 Paytm gateway. This helps to test on production whether small value payments are being routed to Paytm and working successfully, thus avoiding 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 Paytm in the Payment Via field, and click Next.
    Paytm target Provider
  6. Click Publish Rule.
    Paytm Publish Rule

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