  title: Fynn Angebote API (Beta)
  version: 2026-06
  description: >-
    **Beta / Unstable.** The Fynn Angebote (offers) API lets you read, update,
    publish, approve and accept offers programmatically. It is the actively
    maintained surface that replaces the older offer endpoints (still available
    but deprecated, removed on 2026-08-01).


    These endpoints are new and may still change without notice while the
    surface settles. Pin against the dated version and watch the changelog
    before relying on them in production.


    Authenticate every request with an API token of your organisation
    (`Authorization: Bearer api_...`). Documents are returned as media
    references; see the note on each media `id` for how to download the file.
