Sampled — shipped under file-level sampling, not individually fact-checked community attestations: 0✓ / 0✗
Steps POST name, color, and optional description to https://api.buttondown.com/v1/tags Tag names must be unique per newsletter; a duplicate name returns 400 with name_already_exists and the existing tag's id in the response metadata To upsert instead of erroring, send X-Buttondown-Collision-Behavior: overwrite, which updates the existing tag and returns 200 Apply tags to a subscriber at creation time via the tags array on POST /v1/subscribers, or update an existing subscriber's tags Set subscriber_editable: true if subscribers should be able to add/remove the tag themselves via the subscriber portal Known gotchas Tags referenced in a subscriber's tags array that don't exist yet are auto-created — a typo silently creates a new tag instead of erroring Duplicate tag creation fails by default; use the collision-behavior header for upsert semantics public_description is shown to subscribers in the portal, separate from the internal description field
