Prerequisites

You need to register an OAuth app with Notion once. Create a public OAuth integration in your Notion workspace settings. Set the redirect URI to authsome’s callback. The redirect URI must be: 
http://127.0.0.1:7998/auth/callback/oauth
This is the only callback URL authsome’s PKCE flow listens on. Dashboard: https://www.notion.so/my-integrations.
Notion’s standard OAuth flow does not use PKCE. For an MCP-style flow with DCR, use notion_dcr instead.

​
Log in

uvx authsome login notion
The first time, authsome opens a local form at http://127.0.0.1:7998 to collect your client_id and client_secret. They are encrypted under your profile and reused on every subsequent login. A second browser window then opens to https://api.notion.com/v1/oauth/authorize for the authorization step. Verify: 
uvx authsome get notion --field status
# → connected

​
Multiple accounts

Pass --connection <name> on login and on every read command to keep two or more accounts on the same provider side by side. See Multiple connections per provider for the full pattern. 
uvx authsome login notion --connection personal
uvx authsome login notion --connection work

​
Use the token

Run the agent under the proxy. The library tab is for embedding authsome inside a larger Python orchestrator. 
uvx authsome run -- python my_agent.py
Under the proxy, authsome sets NOTION_ACCESS_TOKEN=authsome-proxy-managed in the child’s environment and injects the real token into outbound requests to api.notion.com. The child process never sees the actual value. Refresh tokens are never exported.

​
Override the bundled definition

uvx authsome inspect notion > ~/.authsome/providers/notion.json
# edit scopes, base_url, or anything else
uvx authsome list   # source now shows "custom" for notion
User-registered files always win over bundled definitions. See Provider schema.
