How can I integrate payment processors in my bot which will add all the items user ordered via botpress bot. Add the cost , generate payment link for the cost and show payment successful when payment is received? I know it's done via API of payment processors but there are no good tutorials and I'm stuck on this one, you also need some json code for it to work. If anyone could help, I'll really appreciate that.

Been stuck with it for the past two days. Stripe's webhooks are asking for an URL endpoint. And I don't know which, either my bot's or the webchat Integration link should I provide. And the best part, I can't find either?

There are other payment processors like razorpay but I'm still stuck with API method
