ListActivityFeedAPI mirrors erdo_list_activity_feed: the unified, ranked,
read-only feed (attention items, approvals, workstream events, catalog updates, urgent cause-clusters). Query params carry limit/offset/categories/ scope. Responding to an item routes through /v1/attention/:id/respond and /v1/approvals/:id/decide — this endpoint is a view only. Omit categories for the attention-first default; catalog and execution history are opt-in.
Authorizations
An Erdo API key (erdo_api_...) or scoped token (erdo_token_...).
Query Parameters
Categories is a comma-separated subset of attention, approval, workstream, catalog, job, heartbeat. Empty delegates to the activity service's single product default (attention, approval, workstream); operational run and catalog history is opt-in. Attention + workstream sources appear only when the engine is enabled for your organization.
Scope is following | all (default all). API tokens are org-scoped and carry no per-user follow set, so following degrades to all for a token; it is meaningful only for a user-scoped credential that follows workstreams.
