Developer & API

Settings → Developer manages everything that reaches your account from outside the browser: API tokens for your own scripts, AI assistant connections, the apps you've authorized, OAuth applications you build for others, and webhooks that notify your systems when something changes. Start with the overview to pick the right tool, then use the Tokens pages or the Apps and webhooks pages.
