3.5: Notion Developer Platform
Introducing: the Notion Developer Platform.
Now you (and your coding agents) can write code to sync any data and build any agent tool, all running on our infrastructure. You can also bring your favorite agents into Notion (like Claude, Codex, Decagon, or ones you've built yourself). It turns Notion into one shared canvas with all your data, for your team and agents to work together.
Orchestrate all your team's agents (Alpha)
Bring your favorite agents into Notion with the External Agents API, even the ones you built yourself. Partnered with Claude, Codex, Decagon, and more out of the box. Join the External Agents waitlist →
Sync any data source (Beta)
Sync any data source with an API into your Notion databases — no servers to manage. Powered by Workers running on Notion's infrastructure.
Build custom tools for your agents (Beta)
Write your logic in code and deploy it as a Worker. Deterministic, more reliable than LLM reasoning, and a fraction of the token cost. Read the docs →
Trigger Notion workflows from anywhere (Beta)
Any app can now trigger Notion directly via webhooks. Read the docs →
Meet your Notion Workers
Notion Workers are a hosted runtime for custom code — extend Notion without running your own servers. Free during beta; starting August 11 2026, Workers will run on Notion credits. Read the docs →
A Notion CLI, built for devs and coding agents
Install with curl -fsSL https://ntn.dev | bash.
Use your Notion Agents in any app (Alpha)
With the Notion Agent SDK, embed an agent inside your other tools. Join the Agent SDK waitlist →
Manage all connections from one tab
Every connection — personal, workspace, tokens, internal API — now lives in one place under Settings → Connections.
Agents "hall of fame"
A curated library of the best agents from Ramp, Clay, Vercel, and others — each with a checklist and starter prompt. Browse the collection →
