@woodser Please review this PR :)
I've tested this PR from my side locally and the API works well (CreatePaymentAccount and GetPaymentAccounts tested).

edit: I heard that there is a need for some mass changes in grpc, can we discuss them via email (I have emailed you already)?

I'm currently reviewing this, what code are you using to test CreatePaymentAccount?

I just manually tested it with grpcurl. I'm pretty sure you could test this with haveno-ts but that would require some updates in the protobuf files.

I'm having some issues creating accounts, it seems like some of the forms are incomplete.

Western union:

• missing COUNTRY field
• city field has wrong label "country"

National bank:

• missing TRADE_CURRENCIES field
• BRANCH_ID missing label
• BANK_ID missing label

I will continue reviewing but could you please check the rest as well to make sure there aren't any missing fields etc
