Post to LinkedIn via API

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

LinkedIn API limits & specs

Caption limit3,000 characters
Posts per 24 hours150
Max video size5,120 MB
Max video length10 min
Image formatsJPG, PNG, GIF

Socifyr enforces these limits for you and returns a plain-language reason when a platform rejects a post. Specs reflect LinkedIn’s published API as of November 2026.

Post to LinkedIn 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": ["linkedin-mybrand"], "text": "Hello, LinkedIn!" }'

Prefer an agent? Add the Socifyr MCP server and ask it to “post this to LinkedIn.” Prefer code? The same request works from the CLI (socifyr post) and the TypeScript SDK.
