Call FIRST when unsure whether the connector works or what it can see: 1 health probe, no input. Returns key_status ('valid' | 'rejected' | 'unreachable'), the key's user, its groups[] with member_state, readonly, b3_enabled and notes[].

The connector user's groups, pending invitations included: 1 call, no input. Subgroup parents are appended with member: false. get_group reads one record, even a public group this list omits.

One group by numeric id, short key or URL handle: 1 call; works for public groups the user has not joined. Returns the full record (members_can_* flags included, billing subscription dropped) plus member, membership, parent, url. 403 'Not authorized to show Group.' = hidden from this user; unknown = 404.

One discussion by numeric id or short key: 1 call (2+ with include_items). Returns the full body, topic_id, counters, url; include_items: true embeds list_thread_items as thread_items (items_limit; next_offset says when to page on). Prose: get_thread_markdown; a group's threads: list_discussions.

One group's discussions, newest activity first: 1 call. status defaults to 'open'; description_max_chars (default 1500) caps bodies, description_truncated: true marking a cut; strip_html (default true) gives plain text. Every visible group: list_threads; keywords: search_content. Subgroups are excluded.

Start a discussion in a group: 1 call. Required title, group_id; optional description (+ description_format: 'html' for HTML), private (omit for the group's default), tags, recipients. Returns id, key, url, topic_id. Check list_discussions for duplicates first; to add to a thread use create_comment.

Edit a discussion by id_or_key: 1 call. Pass only what changes: title, description (REPLACES the body: read it first, send the whole text), private, allow_* flags, recipients to add. Cannot move a thread or change its tags; a discarded thread cannot be edited.

Discard a discussion by id_or_key: 1 call. Loomio's SOFT delete: it leaves every list and its text is blanked, but nothing is permanently erased (a group admin can restore it). For a text mistake prefer update_discussion.

One poll by numeric id or short key: 1 call. Returns poll (full details, topic_id), poll_options[], current_outcome, my_stance, url; votes as items: list_thread_items with its topic_id. Results gate: results_visible / results_hidden_reason say whether tallies are present; absent counts mean HIDDEN, never zero.

One group's polls, newest first: 1 call. status defaults to 'active' ('closed', 'all'); description_max_chars caps details; strip_html (default true). Slim rows with poll_options[] and stance_counts when visible (trust results_visible). For member activity use get_participation_report, not this plus list_memberships.

Create a poll: 1 call (2 with discussion_id). Required title, poll_type, options (NO default options; only 'question' takes none) and group_id (standalone) or discussion_id / topic_id (inside a thread). closing_at (ISO-8601, future) is effectively REQUIRED: without it Loomio saves the poll UNOPENED and the result carries opened: false and a warning. An opening poll is announced because notify_on_open defaults to TRUE; pass notify_on_open: false for a quiet create.

Edit an OPEN poll by id_or_key: 1 call (2 with options). Pass only what changes: title, details (REPLACES the text), closing_at (future; opening a draft announces unless notify_on_open is false), options (names to ADD: merged with the current list, so it never removes an option it saw; not atomic), settings. Cannot change poll_type, anonymous, group or tags; a closed poll answers 403.

Discard a poll by id_or_key: 1 call. Loomio's SOFT delete: the poll and its votes leave the thread view, but nothing is permanently erased (a group admin can restore it). To end voting set closing_at to the next full hour with update_poll; no immediate close exists.

The cheapest 'what is new across everything I can see': 1 call lists every visible thread, newest activity first (topic_id, type, title, group_id, counters, url; no bodies). group_id / type filter client-side within the page (one group: list_discussions / list_polls). No date filter upstream: pass since and page with offset until scope.exhausted.

One thread as structured items: 1 call per 500 items by topic_id (+1 by discussion_id or poll_id; pass exactly one). Returns items[] in thread order plus the comments, polls, stances (votes), outcomes and users they reference. Paged by limit / offset under the max_total_chars budget (kinds reads the whole thread); next_offset says where to continue.

The best single call for 'summarise / read this thread': 2 calls by topic_id, discussion_id or poll_id (pass exactly one; +1 per 500 items when the thread has replies) return Loomio's server-rendered Markdown (markdown, chars, truncated). REFUSED while an open poll hides results until the user votes: use list_thread_items. max_chars cuts the END: truncated: true = newest items dropped.

Keyword search over everything the connector's user can see: 1 call. Pass query (prefix match; !word excludes), author_id alone for 'what did X post', or both. Hard cap: at most 20 results, no paging; capped: true means narrow the search. Stance hits on polls with hidden results are DROPPED from a query search; never use search to probe hidden vote reasons.

Rank the members of a group set: 1 call returns Loomio's own report, a row per user sorted by total desc. Scope by group_ids (1-50, counted together) or group_scope: 'my'; top limit rows (default 50, max 500), zero-activity users dropped unless include_inactive. Anonymous polls are excluded; a vote counts in the month its counted stance row was created.

One person's participation across groups: 1 call per group + 1. Required user_id (from list_memberships or a participation row) and group_ids. Returns counts, by_group, sample_events (newest items with urls, not a full list). MONTH-GRAINED: since / until widen to whole months; anonymous polls never count; a vote counts in the month its counted stance row was created.

A group's members: 1 call. Returns memberships[] (user_email only where the connector's user is a group admin), users[], total. Use it to resolve a name to a user_id and ALWAYS before manage_memberships with remove_absent. A non-member gets an EMPTY list, not 403: never report it as an empty group.

Invite users to a group by email and optionally REMOVE members not in the list: 1 call; the connector's user must be an admin of THAT group. Default is additive: new addresses are invited, nobody is touched. DANGEROUS: remove_absent: true removes every member whose email is absent, own user included, with no undo: list_memberships first, then confirm the diff with a human.

Post a comment in a thread: 1 call (2 when discussion_id is a short key). Required body (+ body_format: 'html' for HTML; Loomio stores an omitted format as Markdown) and a target: discussion_id for a top-level comment, or parent_id + parent_type ('Comment' for a threaded reply; 'Poll' / 'Stance' / 'Outcome'). A new thread: create_discussion.

Edit a comment: 1 call. Required numeric id and body (REPLACES the whole text: read it with list_thread_items first), optional body_format. Only the author, or a thread admin where the group allows it, may edit; the thread must be unlocked.

Discard a comment by numeric id: 1 call. Loomio's SOFT delete: the body is blanked and the comment leaves the thread view, but nothing is permanently erased (restorable in Loomio). For a wording fix prefer update_comment.
