Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • approve_postsApprove Postscan change or delete data

    Approve posts so they publish at their scheduled time. This is the only way a post created with create_posts goes out, so show the user exactly what will be posted, where and when, and call this only after they say yes in the conversation, even if they asked you to post it. Can also set PENDING_APPROVAL, REJECTED or NEEDS_WORK. If its scheduled time passed more than 2 hours ago, don't approve it. Tell the user, and only if they agree, create it again with a new time and delete the old one.

  • assign_inbox_conversationAssign Inbox Conversation

    Assign a conversation to a workspace member for follow-up, or omit assigneeUserId to unassign. The assignee must be a member of the workspace (inbox.assigneeNotMember otherwise). Internal to PostFast — nothing changes on the platform.

  • confirm_inbox_actionConfirm Comment Reply or Deletioncan change or delete data

    Carry out a reply or deletion prepared with prepare_inbox_action. Pass its confirmToken with the same itemId, action and text (and workspaceId, if you used one); anything different is rejected. Call it only after the user has seen the preview and said yes in the conversation. Replies on Threads cannot be removed through PostFast, private replies cannot be unsent, and deletions cannot be undone. A token expires 15 minutes after it was prepared and works once. Failures return the underlying inbox.* codes (for example replyTooLong, privateReplyAlreadySent, deleteNotSupported).

  • get_calendar_postCalendar Post Detailsread-only

    Called by the PostFast calendar when a post is opened: its full text, first comment and every image or video. Read-only.

  • get_follower_historyGet Follower Historyread-only

    Daily follower-count snapshots for one connected account (pass its socialMediaId from list_accounts). Returns currentFollowerCount, delta (current − first snapshot in range), trackingStartedAt (when PostFast began recording this account), and a series of { capturedAt, followerCount } points. All counts are strings (bigint); currentFollowerCount, delta, and trackingStartedAt may be absent until the account has its first snapshot. Optional from/to bound the range (ISO 8601; default last 90 days, capped at 365). Snapshots are forward-only — no data before trackingStartedAt. Coverage: Facebook Pag…

  • get_inbox_conversationGet Inbox Conversationread-only

    Fetch one inbox conversation by id, including its server-computed reply capability (canReply, maxReplyLength, windowState, disabledReason) — derive reply ability from these fields, never from hardcoded platform rules. postPreview carries the post's caption and, when available, its public permalink — use the permalink to link the user to the post on the platform (null on Instagram for now). Returns null when the conversation does not exist in the workspace.

  • get_inbox_unread_countGet Inbox Unread Countread-only

    Total unread comment count across all inbox conversations in the workspace (the sum of per-conversation unreadCount). Use mark_inbox_conversation_read after presenting a conversation to the user.

  • get_post_analyticsGet Post Analyticsread-only

    Fetch published posts with their latest performance metrics (impressions, reach, likes, comments, shares). Only returns published posts that have a platform post ID. LinkedIn personal accounts are excluded. Supported: Instagram, Facebook, TikTok, Threads, YouTube, LinkedIn (company pages), Pinterest (Business accounts). Metric counts are returned as strings. Pinterest extras include pin_clicks, outbound_clicks, saves_90d, save_rate_90d (saves are 90-day rolling because Pinterest API does not expose lifetime totals); video pins additionally surface mrc_views, views_10s, avg_watch_time, v50_watc…

  • get_upload_urlsGet Upload URLs

    Get signed upload URLs for media, caption files and LinkedIn documents. Upload your file to the returned URL via PUT, then use the key in create_posts mediaItems; the key of a caption file (.srt or .vtt) goes in controls.youtubeCaptionKey instead, never in mediaItems; the key of a document (.pdf, .doc, .docx, .ppt or .pptx) goes in controls.linkedinAttachmentKey instead, never in mediaItems.

  • list_accountsList Accountsread-only

    List all social media accounts connected to the workspace. Each account includes connectionStatus (CONNECTED or DISABLED) and disabledReason (null unless DISABLED), plus followerCount (latest stored snapshot, a string; absent for platforms without follower data), followerCountUpdatedAt, and inboxCapable (whether the account can appear in the social inbox, i.e. comment ingestion is supported). A DISABLED account will not publish until the user reconnects it — pre-check before scheduling. For a follower trend over time, use get_follower_history.

  • list_gbp_locationsList Google Business Profile Locationsread-only

    List Google Business Profile locations for a connected GBP account (pass its socialMediaId). Use a returned location’s locationId field as controls.gbpLocationId in create_posts.

  • list_inbox_conversationsList Inbox Conversationsread-only

    List comment conversations from the social inbox — comments on your connected accounts' posts, grouped per post, newest activity first. Covers TikTok, Instagram, Facebook Pages, and Threads; an account's inboxCapable flag (from list_accounts) tells you whether comments can flow for it today. Comments arrive within seconds of being posted and only from connect/launch onward (no history backfill). Each conversation carries a server-computed reply capability — canReply, maxReplyLength, windowState, disabledReason — plus unreadCount, status (OPEN | SNOOZED | CLOSED), and assignedToUserId. ALWAYS d…

  • list_inbox_itemsList Inbox Itemsread-only

    Description is built at runtime.

  • list_pinterest_boardsList Pinterest Boardsread-only

    List Pinterest boards for a connected Pinterest account (pass its socialMediaId). Use a returned board’s boardId field as controls.pinterestBoardId in create_posts.

  • list_postsList Postsread-only

    List social media posts with optional filters for specific IDs, accounts, platform, status, and date range. Failed or missed posts carry a lastError { message, code }; codes include MISSED_DISCONNECTED (the account was disconnected when the post was due — reconnect, then retry) and MISSED_NOT_PUBLISHED (passed its scheduled time plus a 2h grace window without publishing). Each post also carries controls { threadsTopicTag, instagramPublishType, facebookContentType, tiktokIsDraft, youtubePrivacy }, each null when unset. Only the field for the post's own platform (its account's platform in list_a…

  • list_tiktok_soundsList TikTok Soundsread-only

    List trending pre-cleared Commercial Music Library tracks for a connected TikTok account. Returns up to 100 trending sounds with musicSoundId, name, artist, duration, and preview/thumbnail URLs. Pass a musicSoundId to create_posts as tiktokMusicSoundId to attach that sound to a TikTok photo, carousel or video post. genre takes raw TikTok values like 'POP', 'HIP_HOP/RAP', 'R&B/SOUL', 'K-POP' (invalid values return the full valid list in the error). The list rotates daily — fetch fresh rather than reusing old ids for display. An unknown countryCode returns an empty list. If the API returns tikto…

  • list_workspacesList Workspacesread-only

    List the workspaces this connection can act in. Use a workspace id as the optional workspaceId argument on other tools to operate across multiple workspaces (the default workspace is used when omitted).

  • list_youtube_playlistsList YouTube Playlistsread-only

    List YouTube playlists for a connected YouTube account (pass its socialMediaId). Use a returned playlist’s playlistId field as controls.youtubePlaylistId in create_posts.

  • mark_inbox_conversation_readMark Inbox Conversation Read

    Mark one conversation read (zeroes its unreadCount). Do this after presenting a conversation's comments to the user. Internal to PostFast — nothing changes on the platform.

  • prepare_inbox_actionPrepare Comment Reply or Deletionread-only

    Prepare a reply to a comment, an Instagram private reply, or a comment deletion WITHOUT doing it. REPLY posts publicly under the comment; PRIVATE_REPLY sends an Instagram private reply that arrives as a direct message (one per comment, within 7 days; check the item's canPrivateReply); DELETE removes the comment on the platform permanently (not supported on Threads). Before a reply, check the conversation's canReply and maxReplyLength. Returns a preview and a confirmToken. Then show the user which comment it is (its author and text) and exactly what will happen, and wait for their yes in the co…

  • record_app_actionRecord Calendar Action

    Called by the PostFast calendar to record which of its buttons was used (open in PostFast, review in chat, reconnect, connect an account, new post), for product analytics. Changes no posts, accounts or settings.

  • reply_to_inbox_itemReply to Inbox Commentcan change or delete data

    Reply publicly UNDER a specific comment — pass the comment item's id (from list_inbox_items), not the conversation id. BEFORE replying, check the conversation's canReply and maxReplyLength and stay within them; the caps are per platform (TikTok 1,200, Instagram 2,200, Facebook 8,000, Threads 500 characters) but the server-computed fields are authoritative — never assume. Failures return inbox.* codes (e.g. replyTooLong, replyNotSupported, rateLimited).

  • search_placesSearch Placesread-only

    Search for a place to geotag a post. Pass free text (min 2 chars, e.g. a venue name or address); returns matching places, each with an id that works as BOTH controls.facebookPlaceId (Facebook feed posts) and controls.instagramLocationId (Instagram single-media posts). Only Facebook Pages that carry location data are returned.

  • send_inbox_private_replySend Instagram Private Replycan change or delete data

    Instagram only: send ONE private reply to a comment — it arrives as a direct message to the commenter and may land in their Message Requests folder. Allowed once per comment, within 7 days of the comment, up to 1,000 bytes (emoji and non-Latin text count multi-byte — roughly 1,000 characters, less with emoji). Check the item's canPrivateReply first (from list_inbox_items). A second attempt on the same comment fails with inbox.privateReplyAlreadySent; other failures include privateReplyWindowExpired and privateReplyNotSupported.

  • set_inbox_conversation_statusSet Inbox Conversation Status

    Triage a conversation: set its status to OPEN, SNOOZED, or CLOSED. Internal to PostFast — nothing changes on the platform.

  • set_inbox_item_stateModerate Inbox Commentcan change or delete data

    Description is built at runtime.

  • upload_from_urlUpload Media From URL

    Description is built at runtime.

  • upload_mediaUpload Media

    Upload a local file to PostFast and get back a media key for use in create_posts. Handles the full flow: detects content type, gets a signed URL, uploads the file, and returns the key and type. Images and videos come back as IMAGE or VIDEO, for mediaItems; an .srt or .vtt caption file comes back as CAPTION, and its key goes in controls.youtubeCaptionKey, never in mediaItems; a .pdf, .doc, .docx, .ppt or .pptx document comes back as DOCUMENT, and its key goes in controls.linkedinAttachmentKey, never in mediaItems.
