👋 @eager silo How can we help?

I'm trying to add UPI payment method from java code

But it is failing with the error unknown_param.

Can you share the request ID (req_xxx) where you received unknown_param error? Here’s how you can find it: https://support.stripe.com/questions/finding-the-id-for-an-api-request

req_vLjYT8ZS3Q26lG

I tried to send request with several combinations

params.put("type", "card");params.put("upi", "customer_upi_id");

params.put("type", "upi");params.put("upi", "customer_upi_id");

params.put("type", "vpa");params.put("vpa", "customer_upi_id");

params.put("type", "upi");params.put("upi", "customer_upi_id");

params.put("type", "vpa");params.put("upi", "customer_upi_id");

Could you share the doc which you refer to send vpa in /payment_methods API? It's not a supported parameter

Your request is using the wrong parameters. You need to send paymentMethodData.upi.vpa. Right now you're just passing vpa

Also, type: 'upi'

Anyway, the UPI feature is still considered a beta and your account does not have access. So regardless of what parameters you pass, it won't work

You should speak to support about using this feature: https://support.stripe.com/contact

Ok thanks.
