Validates no other pending bank transfer invoice exists. Returns the invoice series, amount, currency, and banking info (account holder, IBAN) for the user to complete the transfer. No admin permission required — available to any authenticated member.
Authorizations
Server-to-server authentication. Generate a token in the admin UI at
Settings → Developers → API Access. Send the raw token in the
Api-Token header — there is no Bearer prefix.
Tokens can be marked read-only at creation time, in which case the API
rejects any non-GET request with 403 Forbidden.
