API Command: upi_mandate_modify
The upi_mandate_modify API allows you to modify UPI registration from their website for their existing mandates created for their consumers. If you are not willing to use the upi_mandate_modify API, you can revoke the previous registration mandate using the upi_mandate_revoke API and create a new registration mandate for that customer.
Note:
The upi_mandate_modify API must only be used for updating the UPI registration transaction.

Sample response
Success scenario

{
"status": 1,
"action": "MANDATE_UPDATE",

}
- Update pending

It will be an async call to customer for approving the mandate modification in their PSP app by entering their MPIN. After the UPI mandate is modified, you can check the UPI mandate status, or can consume the UPI mandate modification webhooks from PayU end. For checking UPI mandate status, refer to Get Mandate Status API.
Note:
UPI Mandate Modify is only applicable for the UPI Collect registration transactions. It does not works for the mandates created using the UPI Intent mode.
