Post to Threads via API

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

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

Post to Threads 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": ["threads-mybrand"], "text": "Hello, Threads!" }'

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