--- title: Users url: https://platform.claude.com/docs/en/api/beta/organization/analytics/users --- # Users ## List User Activity **GET** `/v1/organizations/analytics/users` Get per-user activity for a given day, with cursor-based pagination. Returns activity metrics for each user in the organization, sorted by email address. Use `group_by[]` for per-RBAC-group aggregates, or `filter[]` to scope results to specific members, groups, or a chat project. Available to organizations on a Claude Enterprise plan. Requires an API key with the `read:analytics` scope. ### Query parameters - `date: optional string` UTC date in YYYY-MM-DD format. The day to get user activity for. Data is typically available with a 1-day lag (varies by query; the error for a too-recent date names the latest available day) and may be revised by a few percent over the following days. No earlier than 2026-01-01. format: date - `ending_date: optional string` UTC date in YYYY-MM-DD format. End of the date range (exclusive); only valid with `starting_date`. Data is typically available with a 1-day lag (varies by query; the error for a too-recent date names the latest available day), so this can be at most today — which is also the default when omitted, resolved once when the first page is served and reused for the rest of the pagination sequence. At most 366 days after `starting_date`. format: date - `filter: optional array of string` Filters as `dimension:value`, e.g. `filter[]=rbac_group_id:{id}`. Repeat the param for OR within a dimension and across dimensions for AND. Supported dimensions on this endpoint: `project_id`, `rbac_group_id`, `user_id`. Value forms: `project_id` takes a tagged project id (`claude_proj_...`) and scopes each member's row to their claude.ai chat activity within that project (it cannot be combined with `group_by[]` or an `rbac_group_id` filter); `rbac_group_id` takes the tagged id (`rbac_group_...`, as emitted in responses and by the spend-limits API) or a bare group UUID, and matches users who held the group at any point during each covered UTC day (time-of-usage attribution); `user_id` takes a tagged user id (`user_...`), as emitted in responses. An unsupported dimension returns 400. At most 100 entries. maxItems: 100 - `group_by: optional array of "rbac_group_id"` Dimensions to break results out by (e.g. `group_by[]=rbac_group_id`). Supported on this endpoint: `rbac_group_id`. Rows are already per-member, so the one supported grouping aggregates them per RBAC group instead. Grouped rows carry the requested dimension values as additional fields and paginate like ungrouped responses via `next_page`; an unsupported dimension returns 400. `rbac_group_id` attributes a user to every group they held at any point during each covered UTC day, so grouped rows are not an exclusive partition and can sum above org-level totals. At most 100 entries. maxItems: 100 - `limit: optional number` Number of results per page (1-1000, default 100). minimum: 1, maximum: 1000 - `order: optional "asc" or "desc"` Sort direction: `asc` or `desc`. Defaults to `asc` for the endpoint's sort column and to `desc` when `order_by` names a metric (a top-N ranking). Applies to `order_by`, or to the endpoint's default sort field when `order_by` is omitted. - `"asc"` - `"desc"` - `order_by: optional string` Sort field. Restricted to the endpoint's sort column plus its rankable metrics (metrics default to descending; a few metrics rank in date-range mode only, per the endpoint's documented orderable set). - `page: optional string` Opaque cursor from a previous response's `next_page` field. - `starting_date: optional string` UTC date in YYYY-MM-DD format. Start of a date range (inclusive). Enables rollup mode: one row per entity aggregated over the whole range — addable counters are summed across days, and a distinct count is never summed where summing could double-count (a field's range value is recomputed exactly over the window, approximate via HLL with typical error under 2%, null, or — for the creation-event counts, whose per-day values cannot overlap — a per-day sum that is itself exact; each field's own description says which). Use either `date` or `starting_date`, not both. Data is typically available with a 1-day lag (varies by query; the error for a too-recent date names the latest available day) and may be revised by a few percent over the following days. No earlier than 2026-01-01. format: date ### Returns - `BetaUserActivity object` Response for GET /v1/organizations/analytics/users. - `data: array of object` - `chat_metrics: object` Claude.ai activity metrics for a single user on a given day. - `connectors_used_count: number` Number of MCP connector invocations. - `distinct_artifacts_created_count: number` Number of distinct artifacts created.
