How to call it

A starting template for Notion. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.

# Uses OAuth. Exchange your credentials for an access token first.
curl -s "https://developers.notion.com/ENDPOINT" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Accept: application/json"

This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

Where this listing comes from

Notion — common questions

Answered from what our own scheduled checks found, not from the provider's marketing.

Is Notion free to use?

Notion is listed in our free catalogue, but it requires OAuth, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.

Does Notion need an API key?

Notion uses OAuth rather than a simple key, so you register an application and complete an authorisation flow before making calls. That is more setup than a key, and it is why OAuth APIs are harder to try quickly.

Can I call Notion from browser JavaScript?

Not directly. Notion did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.

Is Notion still working?

Yes, as of 2026-09-18. Our automated check reached Notion and recorded a 100% reliability score with a median response time of 1086 ms. We re-check on a schedule, and this page updates with the result.

Is Notion available over HTTPS?

Yes. Notion serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
