It stores the words you send; it writes none itself. A destination must already be on the piece, each version must carry its words, and a destination that already published refuses, because its copy is the record of what went out. It saves the draft only; nothing is published. Not for the piece's own copy — that is `posts.api_fill_step`. 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. ## OpenAPI ````yaml /openapi.json post /api/v1/tools/posts.save_variants openapi: 3.1.0 info: title: Goosy Bear API version: 1.0.0-beta summary: Manage workspace content, projects, Data tables, Pages, library and credits. description: >- BETA. This API is in beta: paths, request shapes and response envelopes may change, and every response carries an `x-goosy-api: beta` header for as long as that is true. A change is additive, or it is deprecated first: a response to a call that uses a deprecated feature carries `Deprecation` and `Sunset` headers, and nothing is removed until at least 90 days after its deprecation. Pin the OpenAPI document you generated against and re-generate when it changes. servers: - url: https://app.goosybear.ai description: Production security: - tenantApiKey: [] paths: /api/v1/tools/posts.save_variants: post: tags: - posts summary: Call posts.save_variants description: >- Save the version written for each destination of a post — 'save these captions for Instagram and LinkedIn', 'here's the LinkedIn version of this post'.

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. schema: type: string maxLength: 200 requestBody: required: true content: application/json: schema: type: object properties: piece_id: type: string format: uuid description: >- The piece's id, as posts.create_pieces, content.create_request, content.status or schedule.read return it. variants: type: array items: type: object properties: platform: type: string description: >- The destination this version is for.

Omit where the destination only has a caption. publish_at: type: - string - 'null' description: >- This destination's OWN time, ISO 8601 UTC — a per-platform offset from the piece's anchor. Omit unless the brief asked for one; the piece's own time covers every destination that has none. aspect_ratio: type: - string - 'null' description: >- Override the managed default aspect for this destination.

One word each, no spaces. alt_text: anyOf: - type: string maxLength: 1000 - type: 'null' description: >- What the creative SHOWS, for a reader who cannot see it — the subject, what they are doing, the setting.

Omit on destinations that do not. location_label: anyOf: - type: string maxLength: 200 - type: 'null' description: >- The place this post is tagged at, as a human label ("Northwind Trading Co. · Portland, OR").

Only a destination the operator named. link_sticker_label: anyOf: - type: string maxLength: 60 - type: 'null' description: >- The words ON the link pill ("See the menu"). Ignored without link_sticker_url — a label with no destination is a pill that goes nowhere. music_label: anyOf: - type: string maxLength: 200 - type: 'null' description: >- The track as the platform NAMES it ("Golden Hour · JVKE"). Only a track the operator picked — never one you chose for them. alt_text: anyOf: - type: string maxLength: 1000 - type: 'null' description: >- What THIS frame's picture shows, for a reader who cannot see it.

Omit for the platforms' own 5-second still. additionalProperties: false minItems: 1 maxItems: 10 description: >- EVERY frame of this story, in order — the first entry is the frame a viewer sees first. This REPLACES the whole rail: any frame you do not list is removed. expires_at: type: - string - 'null' description: >- When the story stops being visible, ISO 8601 UTC. Normally 24 hours after it posts; omit unless the operator said otherwise. highlight_name: anyOf: - type: string maxLength: 100 - type: 'null' description: >- The highlight the story is saved into after it expires. Only one the operator named. replies_mode: anyOf: - type: string enum: - everyone - followers - 'off' - type: 'null' description: >- WHO MAY REPLY to the story.

Including this REPLACES the whole rail. required: - platform additionalProperties: false minItems: 1 maxItems: 12 description: >- Every destination's version, in ONE call.
