# UPI Collect Mandate transactions 




### Step 1.1. Verify VPA


It is recommended to validate the customer's VPA (Virtual Payment Address) prior to initiating the Mandate transaction request, and this can be accomplished by utilising mandate details regarding the vpa handle from the response of the [Verify VPA API](https://docs.juspay.in/api-reference/docs/express-checkout/verify-vpa).




### Step 1.1. UPI Txn - Collect


UPI Collect mandate transactions happen through the webcollect flow, wherein the user enters his VPA and receives a collect mandate register request notification from the corresponding UPI PSP app. On approving the request, mandate will be registered and auto debit occurs every cycle.
