You can use the Recurring Payments APIs to perform various actions using UPI as a payment method.

API-wise Integration Checklist for UPI🔗

UPI Registration using Standard Checkout🔗

We recommend that you create a single customer id rather than multiple customer ids for the same customer. If their details change, you can use the Edit Customer Details API. Duplicate validation is done based on email ID and phone number.
Use the fail_existing : 1 parameter so that the API returns the same details of the customer created earlier. If the fail_existing : 0 is used, the API throws an error and does not fetch the customer ID previously created. This can help in the end-user journey experience if a customer is signing up despite having signed up earlier.
Use the Payments Downtime API to check for any ongoing downtimes that may impact the UPI Recurring.
Ensure you pass all the token parameters while creating an Order for the authorization transaction using the Standard Checkout method.
Ensure you pass the value of the recurring parameter as 1 in the Create an Authorization Payment API. If not passed, it would be considered a one-time payment. Once the authorization payment is made, we request you verify the payment signature at your backend.
To check the status of the token ID use the Fetch Token API.
Enable webhooks to check the status of the token and payments and the registration link. Use this only if your business is using it in a non-critical way. In critical scenarios, we recommend that you fetch APIs.
A pre-debit notification is sent before the payment is deducted by the issuing bank. It is recommended that you check the presentment time in the FAQ document before proceeding with the recurring payments.

UPI Registration using a Registration Link🔗

Ensure to pass the below parameters while creating a registration link using the API:
1. Customer details such as name, email, and contact.
2. sms_notify and email_notify as 1 to send notifications to customers.
3. amount as 0 and type as link.
4. description of the link.
5. subscription_registration details such as:
  - method as upi
  - max_amount as 500
  - frequency as monthly or as_presented

Create Subsequent Payments🔗

Ensure the token_id passed is for the linked customer_id while creating a recurring payment.
Use webhook to get real-time updates of payment.
