Post series
One post’s daily gains over the range (zeros filled). The post must be tracked for your organization (and in campaign_ids when given), otherwise 404. Live: new post readings show up on the next call.
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Query Parameters
Read one of your child brands instead of the organization that owns the key. Any id that is not one of your brands answers 404.
First day, YYYY-MM-DD. Default: 29 days ago.
Last day, YYYY-MM-DD. Default: today (UTC).
Comma separated campaign ids (from /content/filters). One id reads that campaign; several read their union, a post in two of them counting once. Every id must belong to your organization.
The post, as platform:post id (the id of /content/top_posts or /posts).
Or a legacy numeric post id.
