The merchant-pays-user flow (e.g. ATM or refund):
1. The merchant publishes an *invoice_request* which contains offer fields
which refer to its attempt to send money, including an amount.
2. The user sends an *invoice* over the lightning network for the amount in the
*invoice_request*, using a (possibly temporary) *invoice_node_id*.
3. The merchant confirms the *invoice_node_id* to ensure it's about to pay the correct
person, and makes a payment to the invoice.
Agree, we should definitely add support for refunds at some point. Leaving this link here in case anyone is able to look into this: https://docs.rs/lightning/latest/lightning/offers/refund/struct.Refund.html
With https://github.com/lndk-org/lndk/issues/181, we should be able to receive the invoice
back over a local physical link so that it can be paid with the existing pay-invoice
. There would need to be some way to validate the invoice
received is indeed in response to the invoice_request
before using pay-invoice
though.

we have
and I'd like to have this capability.
It would make sense to be able to be able to automatically wait for the invoice to be received and then show the invoice. In addition, it would also be nice to be able to wait for the invoice to be received and then automatically pay it if the invoice amount matches the invoice_request amount.
