# Retrieve campaign statistics

`GET /api/v1/campaigns/{id}/stats`

## Request

- Base URL: `https://api.sendly.now`
- URL: `https://api.sendly.now/api/v1/campaigns/{id}/stats`
- 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: `campaigns:read`)

Delivery and engagement counters for one campaign, plus the rates derived from them. Every number is a materialized counter on the campaign row, so this is a single indexed read regardless of how many emails the campaign sent — cheap enough to poll while a campaign is in flight.

Rates are percentages (0–100) against `sent`, and are 0 before anything has been sent.

Requires the `campaigns:read` scope — View your campaigns and their performance.
