Google+ API
The Google+ API is the legacy read interface to the Google+ social platform, exposing public activities, comments, and people resources via 9 GET endpoints. Callers can list a person's activities by collection, fetch a single activity or comment, list commenters or resharers on an activity, and search people by query. Google+ as a consumer product was shut down in 2019, so this spec is preserved primarily for historical archival reads, migration tooling, and reference where legacy Google+ identifiers still appear in customer datasets.
