# List the contacts behind a campaign's engagement

`GET /campaigns/{id}/engagement`

Returns the contacts in one of a sent campaign's engagement groups. non_openers covers contacts the campaign actually sent to who did not open it — queued and cancelled deliverables are excluded, since they never had the chance.

## Query parameters

- `type` 'openers' | 'clickers' | 'non_openers' | 'bounced' | 'unsubscribed', required
- `per_page` integer
