Post to Facebook

No card for the free tier · one API for every network · full MCP access

Availability: Live now — connect a Facebook account and post today.

The fastest way: ask your agent

Connect PostLake's hosted MCP server to your AI assistant (Claude, ChatGPT, Cursor and others), then just ask it to post to Facebook. No API key to paste — it authorizes over OAuth. See the MCP guide.

Post to Facebook via the API

Connect your Facebook account, then one call publishes to it (and any other accounts under the profile). No media required for a text post:

curl -X POST https://api.postlake.dev/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Hello from PostLake 👋",
    "platforms": ["facebook"],
    "profile": "my-brand"
  }'

You get back one normalised shape — a post id plus a targets list with the live URL. Full detail in Publishing a post.

Facebook specifics

Why PostLake for Facebook

No app setup

PostLake manages the Facebook connection for you — no developer app to register or platform review to run yourself.

One response for every network

Post to Facebook and other networks in one call and get back a single normalised shape — your code never branches per platform.

Agent-safe

Idempotency keys mean a retrying agent never double-posts, and analytics come back normalised so an agent can decide what to post next.

Honest pricing

A free tier to start, then usage-based credits — one per post (X costs more). You only pay for posts that actually publish.

Common questions

How do I post to a Facebook Page via API?

Connect a Page to PostLake (you pick which Page at connect time), then POST /v1/posts with "platforms": ["facebook"]. PostLake handles the Graph API and returns one normalised result.

Can I post to a personal Facebook profile?

No — Facebook's API is for Pages, not personal profiles. PostLake posts to a Page you manage, which is what the platform allows.

Do I need a Meta app for Facebook posting?

Facebook posting via API requires Meta app-review — but PostLake runs the managed app, so there's no review for you to pass yourself.
