**User Flow**:
1. User visits widget URL
2. Selects provider (Fitbit, Garmin, etc.)
3. Completes OAuth with provider
4. Redirected to success URL
5. Webhook sent to your endpoint with `type: "auth"`

**Important**: Always open auth URLs in a real browser, not WebView or iFrame (OAuth security requirement).
