# List the best-performing campaigns

`GET /api/v1/analytics/top-campaigns`

## Request

- Base URL: `https://api.sendly.now`
- URL: `https://api.sendly.now/api/v1/analytics/top-campaigns`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `better-auth.session_token`
  - OAuth 2 (authorization code, authorization URL `https://app.sendly.now/api/auth/oauth2/authorize`, token URL `https://app.sendly.now/api/auth/oauth2/token`, scopes: `analytics:read`)

Campaigns sent in the window, ranked by open rate, capped at 50 rows. Not cursor-paginated: a leaderboard is a top-N by definition, and paging one would mean re-ranking on every page.

`from` defaults to 30 days ago and is clamped to at most 90 days back; `to` defaults to now. A wider request is narrowed rather than refused, and the `window` field states the range actually covered — read it before comparing two responses.

Requires the `analytics:read` scope — View your sending analytics and engagement metrics.
