Get the campaign reports overview
Aggregates every campaign sent in the range into totals, average rates and a trend against the immediately preceding period of the same length. Trends stay flat at 0 unless both from and to are supplied, because there is no prior window to compare against. The cross-channel open rate is deflated by SMS and push deliveries, which emit no open event, so pass channel=email when the figure is presented as an open rate. Requires the campaigns:read scope.
Authorizations
An organization API key, prefixed bk_live_. Takes precedence over Authorization when both are sent. The key is bound to one organization, and the scopes it was issued with are enforced per endpoint.
Headers
Required when authenticating with an access token. Optional with an API key, whose own organization binding is authoritative; a value contradicting it is refused with 403.
