A report is a named definition of criteria (columns, rules, group_bys) which is stored. A stored report can be run for a given timeframe, producing the report results. The results are a count of the events for each column in that timeframe that match the rules and which are optionally grouped by event properties.
Reports can be shared outside LeadConduit such that anyone who has the
URL to the shared report can view it without authentication. Each
shared report URL contains a generated, unique, unguessable token,
which is stored as a property in the report definition. To create the
token for a report, use the share endpoint. To stop sharing a report,
use the unshare endpoint, which will clear the token.'
