The notifications endpoint returns the current user's notification inbox — the same data that powers the "Hey!" menu in Basecamp. Notifications are grouped into three categories: unread items, recently read items, and memorized items.
Each notification represents activity on a recording (message, to-do, comment, etc.) that the current user has been notified about. Notifications track unread state, unread counts, and timestamps for when items were read or received.
Endpoints:
GET /my/readings.jsonwill return the current user's notifications grouped intounreads,reads, andmemories.
