How do I use my PhonePe UPI ID to set up an AutoPay on an external merchant’s platform?

You would only need to enter any one of your PhonePe UPI IDs while setting up an AutoPay on an external merchant’s platform. 

Note: You would be able to do this only if the external merchant allows you to use UPI as a payment mode for your AutoPay.
