Post to Facebook via API
Publish to Facebook from an AI agent, a CI pipeline, or any app — one call through the Socifyr MCP server, REST API, CLI, or TypeScript SDK. Connect Facebook once, hand your agent a key, and it never sees your Facebook tokens.

Socifyr enforces these limits for you and returns a plain-language reason when a platform rejects a post. Specs reflect Facebook’s published API as of November 2026.
Post to Facebook in one call
curl -X POST https://api.socifyr.com/api/content/text \
-H "Authorization: Bearer sk_your_key" \
-H "X-Workspace-Id: ws_abc123" \
-H "Content-Type: application/json" \
-d '{ "connections": ["facebook-mybrand"], "text": "Hello, Facebook!" }'Prefer an agent? Add the Socifyr MCP server and ask it to “post this to Facebook.” Prefer code? The same request works from the CLI (socifyr post) and the TypeScript SDK.
