Vincent, have you succeeded in implementing this? Started trying this myself and it would be nice to team up on this.
Steps I took:
Ok, so now you can enter an amount and save it, but still to send it to Stripe. Don’t have the time to complete the manual, but have a look at their docs: https://stripe.com/docs/development, https://stripe.com/docs/payments?payments=popular, https://stripe.com/docs/payments/no-code and https://stripe.com/docs/payments/checkout
according to this doc, it is supposed to be trivial to implement
Cant find any documentation other then this though :(
