Facebook Automation

Facebook Automation

Automate Facebook Page operations -- create and schedule posts, upload videos, manage Messenger conversations, retrieve page insights, and handle scheduled content -- all orchestrated through the Composio MCP integration.

Toolkit docs: composio.dev/toolkits/facebook

Setup

1. Connect your Facebook account through the Composio MCP server at https://rube.app/mcp
2. The agent will prompt you with an authentication link if no active connection exists
3. Once connected, all FACEBOOK_* tools become available for execution
4. Note: This toolkit supports Facebook Pages only, not personal Facebook accounts

Core Workflows

1. Discover Managed Pages

List all Facebook Pages you manage to get page IDs and access tokens for subsequent operations.

Tool: FACEBOOK_LIST_MANAGED_PAGES

Parameter	Type	Required	Description
fields	string	No	Comma-separated fields (default: id,name,access_token,category,tasks,about,link,picture)
limit	integer	No	Max pages per request (default: 25)
user_id	string	No	User ID (default: me)

Always run this first to cache page_id values. Avoid repeating discovery calls -- cache the results.

2. Create & Schedule Posts

Publish or schedule text posts with optional links on a Facebook Page.

Tool: FACEBOOK_CREATE_POST

Parameter	Type	Required	Description
page_id	string	Yes	Numeric Page ID from managed pages
message	string	Yes	Text content of the post
published	boolean	No	true to publish immediately, false for draft/scheduled (default: true)
scheduled_publish_time	integer	No	Unix UTC timestamp; must be at least 10 minutes in the future
link	string	No	URL to include in the post
targeting	object	No	Audience targeting specifications

When scheduling: Set published=false and provide scheduled_publish_time as a Unix UTC timestamp.

3. Create & Schedule Video Posts

Upload and schedule video content on a Facebook Page.

Tool: FACEBOOK_CREATE_VIDEO_POST

Parameter	Type	Required	Description
page_id	string	Yes	Numeric Page ID
file_url	string	Conditional	URL of the video file (provide file_url or video)
video	object	Conditional	Local file upload with name, mimetype, s3key
title	string	No	Video title
description	string	No	Video description
published	boolean	No	Publish immediately (default: true)
scheduled_publish_time	integer	No	Unix timestamp for scheduled publishing

---

4. Manage Scheduled Posts

Review, reschedule, update, or publish scheduled content.

Tools:

• FACEBOOK_GET_SCHEDULED_POSTS -- List scheduled/unpublished posts for a page
  • page_id (required), fields, limit (max 100)
• FACEBOOK_RESCHEDULE_POST -- Change the scheduled publish time
• FACEBOOK_UPDATE_POST -- Edit caption/text on an existing post
• FACEBOOK_PUBLISH_SCHEDULED_POST -- Publish a scheduled post immediately

---

5. Read Page Messenger Conversations

Retrieve inbox conversations and message threads between users and your Page.

Tool: FACEBOOK_GET_PAGE_CONVERSATIONS

Parameter	Type	Required	Description
page_id	string	Yes	The Facebook Page ID
fields	string	No	Fields to return (default: participants,updated_time,id)
limit	integer	No	Conversations to return, max 25

Then retrieve full message threads:

Tool: FACEBOOK_GET_CONVERSATION_MESSAGES

Parameter	Type	Required	Description
page_id	string	Yes	Page ID that owns the conversation
conversation_id	string	Yes	Conversation ID in t_ format (e.g., t_3638640842939952)
fields	string	No	Default: id,created_time,from,to,message
limit	integer	No	Messages to return, max 25

6. Send Messages & Mark as Seen

Respond to users via Messenger and mark messages as read.

Tools:

• FACEBOOK_SEND_MESSAGE -- Send a text message from the Page to a user via Messenger
• FACEBOOK_MARK_MESSAGE_SEEN -- Mark a user's message as seen by the Page

Warning: Both tools cause user-visible side effects. Only call after explicit confirmation.

Known Pitfalls

Pitfall	Details
Scheduling too close to now	FACEBOOK_CREATE_POST with scheduled_publish_time less than ~10 minutes in the future returns HTTP 400 -- enforce a larger buffer for bulk runs
Unix UTC timestamps required	scheduled_publish_time must be Unix UTC -- timezone conversion mistakes cause off-by-hours scheduling or validation failures
Cursor-based pagination	FACEBOOK_GET_SCHEDULED_POSTS and FACEBOOK_GET_PAGE_CONVERSATIONS return subsets -- follow paging cursors to get complete data
Large conversation payloads	Requesting embedded messages in conversations creates huge payloads -- use FACEBOOK_GET_CONVERSATION_MESSAGES for full threads instead
Video processing delays	Uploaded videos may remain in processing state -- only schedule via FACEBOOK_CREATE_VIDEO_POST after the upload is usable
Cache page IDs	Repeating FACEBOOK_LIST_MANAGED_PAGES calls adds latency -- cache page_id per workspace/run
Pages only	This toolkit does not support personal Facebook accounts -- only Facebook Pages
Write operations need confirmation	FACEBOOK_SEND_MESSAGE and FACEBOOK_MARK_MESSAGE_SEEN cause user-visible side effects -- only call after explicit user confirmation
