Fiken API client and OAuth2 for Go — shared by gcbill, adaa and sokkel-billing https://git.simenandre.no/fiken/atom/?h=v0.3.1 2026-10-18T11:01:54Z 2026-10-18T11:01:54Z Simen A. W. Olsen hello@simenandre.no 2026-10-18T11:01:54Z urn:sha1:53323a0671a3bfe86e7cff75ee5269f60c01ba05 Fiken's PUT replaces the whole contact and rejects a body missing required fields ("'name' er påkrevd"), so a partial update cannot work. Merging over the raw JSON rather than over Contact keeps every field Fiken holds, including the ones this package does not model — a struct round-trip would silently blank an address, its contact people and its notes. 2026-10-18T10:58:37Z Simen A.

A contact created without one defaults to NOK, so anything invoiced in another currency failed at the draft with nothing to explain it. Adds Currency and Language to NewContact, plus Contact and UpdateContact for fixing one already made. 2026-10-17T12:27:46Z Simen A. W.

The login command named when a grant cannot be renewed is now injected (Source.LoginCommand): it was hardcoded to gcbill's, which would have sent every other caller's operator to a command that does not exist.
