Facebook Group Members Scraper

Extract the active, visible members of public Facebook groups — the people who actually post and comment — as a clean, deduplicated, enriched list. Cookieless, no login, MCP-ready.

What it does

Point it at one or more public Facebook groups. It pages through the group's recent public posts (and their comments), then deduplicates every author into a single member record enriched with their activity in that group.

Field	Description
name	Member display name
memberId	Facebook pfbid identifier
profileUrl	Direct Facebook profile link
activityType	poster, commenter, or both
postCount	Posts authored in the scanned window
commentCount	Comments authored in the scanned window
reactionsReceived	Reactions on their scanned posts
firstSeenAt / lastActiveAt	ISO 8601 activity window
sampleText / sampleUrl	A snippet of their most recent activity
groupUrl / groupId / groupSlug	Source group

When to use it

• Build a lead list of engaged people in a niche community group.
• Find the most active contributors / potential influencers in a group.
• Community research: who drives the conversation, how recently.

When NOT to use it

• This does not return a group's full, login-gated member roster. Facebook hides the complete member list behind login; no cookieless data source exposes it. This actor returns members who are publicly active (posted or commented in the visible window).
• For group post content (not members), use facebook-groups-scraper.
• For Facebook ads, pages, or marketplace, use the matching actor in this portfolio.

Input

{
  "groupUrls": ["https://www.facebook.com/groups/vegrecipes"],
  "maxMembers": 200,
  "maxPostsPerGroup": 100,
  "includeCommenters": true,
  "deepComments": false,
  "sortBy": "RECENT_ACTIVITY"
}

• groupUrls / groupIds — one or more public groups (URL slug or numeric ID).
• maxMembers — cap on unique members per group (also caps your cost).
• maxPostsPerGroup — how many recent posts to scan.
• includeCommenters — count comment authors as members (default on).
• deepComments — fetch full comment threads for maximum member yield (extra cost).
• sortBy — RECENT_ACTIVITY (active members) or TOP_POSTS (high-engagement members).

Output

One dataset row per unique member. Example:

{
  "name": "Satish Chandra",
  "memberId": "pfbid02d8...",
  "profileUrl": "https://www.facebook.com/pfbid02d8...",
  "activityType": "both",
  "postCount": 2,
  "commentCount": 7,
  "reactionsReceived": 34,
  "lastActiveAt": "2026-06-25T11:04:00.000Z",
  "groupSlug": "vegrecipes"
}

Pricing

Pay-per-event:

• Member found — $0.006 per unique member returned.
• Actor start — $0.00005 per run.

You are billed only for unique members actually returned. maxMembers is your hard cost ceiling.

Coverage & limits

• Public groups only. Private / closed groups return no data.
• Yield depends on group activity: a busy group surfaces many members; a quiet or heavily-moderated group surfaces few. The actor reports exactly how many posts it scanned and why it stopped.
• Members are derived from visible public activity, not the hidden roster. Silent members who never post or comment will not appear.

Legal

Use only for lawful purposes and in compliance with Facebook's Terms of Service and applicable data-protection law (including GDPR/CCPA where relevant). This actor accesses only publicly visible content and does not bypass authentication. You are responsible for how you use the data.
