Link a PayU Account

PayU is available to eligible India-based sellers with an approved PayU merchant account. Buyers can use the payment methods enabled for that account, such as UPI, cards, net banking, and EMI.

Before you begin​

  • Complete PayU merchant onboarding and account verification.
  • Keep your Merchant Key and Merchant Salt (v1) private.
  • Disconnect any other active 3DIMLI payment gateway.

Find your PayU credentials​

  1. Sign in to the PayU Dashboard.
  2. Open Collect Payments -> Payment Gateway -> Key/Salt.
  3. Copy the production Merchant Key and Merchant Salt (v1).

Connect PayU to 3DIMLI​

  1. Open Dashboard -> Settings -> Payment Gateway.
  2. Select PayU.
  3. Enter the Merchant Key and Merchant Salt.
  4. Save and confirm the gateway shows as connected.
  5. If your PayU card shows a webhook URL, add that exact URL in PayU's webhook settings.

Never send your Merchant Salt through chat, email, screenshots, or support tickets. 3DIMLI support does not need the secret value to troubleshoot normal setup issues.

Currency and checkout​

  • INR stores charge the saved INR total.
  • USD stores show USD prices and convert the checkout total to INR for PayU processing.
  • PayU decides the final available payment methods and any international acceptance for your merchant account.

Use Store Currency to review USD and INR setup.

Refunds​

Start eligible refunds from the 3DIMLI order or refund workflow. The refund is sent through the same PayU merchant account that processed the payment.
