Post to Slack via API

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

Slack API limits & specs

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

Post to Slack 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": ["slack-mybrand"], "text": "Hello, Slack!" }'

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