}Call posts.fill_step
Write what a post is built from, its name and its own copy — ‘here’s what this post should say’, ‘this post is built from Tuesday’s episode’, ‘rename this post’. Its copy is what every destination’s version is shaped from, so write it before each destination’s version. It saves the draft only; nothing is published or sent. Not for one destination’s own version — that is posts.api_save_variants.
Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with workspace_ambiguous and lists the choices — offer them, never pick one.

}Authorizations
An API key minted at Settings › API & MCP. Send it as Authorization: Bearer <key>. A key carries its holder's own permissions, resolved on every call — revoking a membership closes the key's reach immediately. Keep it in an environment variable (GOOSY_API_KEY), never in a committed file.
Headers
Your own id for this request, echoed back and recorded on the audit trail. 1–128 characters from A–Z a–z 0–9 . _ : -, starting with a letter or digit; anything else is replaced by a generated id.
128Your key for this write: send the same key when you retry and the first result comes back instead of a second action. Keys are honoured for at least 24 hours. 1–200 visible ASCII characters. Replaces the idempotency_key body field, which still works until 2026-12-31; this action needs a key on one of the two, and the header is the one to send.
200Body
The piece's id, as posts.create_pieces, content.create_request, content.status or schedule.read return it.
Rename the piece.
Step 1 — what this piece is built from. Moves as a PAIR with source_ref: scratch takes none, every other kind requires one.
video_unit, image, document, scratch The id of the final named by source_kind.
The piece's own copy — the canonical version every destination's version is shaped from.
Deprecated on REST: send the Idempotency-Key header instead. Still accepted until 2026-12-31; if both are sent they must match.
1 - 200Which workspace to run in — its slug. Omit to use your default. With more than one reachable workspace and no default, the call is refused and the choices are listed.
1Response
The call was admitted and dispatched. ok says whether the tool succeeded — a refusal the tool itself produced is still a 200, exactly as it is a successful JSON-RPC result over MCP.
- Option 1
- Option 2
The tool ran and answered.
What was saved on the piece: title, source, master_content.
True when this is the first result of an earlier call with the same idempotency_key, returned without running anything again.
The slug of the workspace this call ran in.
Which workspace this call ran in, and how that was decided. Present on every workspace-scoped result.
