I am trying to find an online solution for a multi-vendor application. In this application, there will be multiple vendors and multiple customers and I want to add a feature for vendors to collect payment on their UPI id from customers.
I am thinking that the vendor will give us their VPA of UPI id and I will save that VPA address directly in the database when the customer will try to pay that vendor I will retrieve VPA from the database and make a payment to that vendor.
I tried razor pay, cash-free, PayU, Paytm SDK but no one has the solution. earlier I used this library https://pub.dev/packages/upi_india but it is not working now.
There is one solution I found https://developers.google.com/pay/india/api/otherapis/omnichannel/initiate-payment But for this user's have to have google pay installed on their phone
and one other solution is Razorpay routes https://razorpay.com/docs/payments/route/ But I don't want to integrate this because for using this feature we need the vendor's bank account details and I don't want to collect bank account detail from the vendor.
Any answers or links to this solution are very much appreciated. Thank you
