# QR code integration

> Generate UPI QR codes from the deep link returned in the payin quotation response.

## Generating UPI QR codes

When you create a payin quotation for a UPI payment method, the API response includes a `deep_link` field with all the payment details. Pass this value directly to a QR code library to generate a scannable UPI QR for your user.

See the [sample response](/api-reference-exchange/endpoint/payin/quotation#response-data-deposit-instructions-deep-link) for the payin quotation UPI payload.

<Info>
  Use the `deep_link` exactly as returned. Modifying it may break payment parsing or delay reconciliation.
