Query Parameters

Space-scoped reputation

This endpoint has a space in context, so it accepts the opt-in reputation params. They add a spaceReputation field to the message sender’s user, alongside the always-present reputation total. Requires the reputation bundle. See the Reputation data model for the full contract.

spaceReputationId · string

Adds spaceReputation to each returned user. One of: a space <uuid> (that space’s bucket), none (the project-general bucket), or context (the space derived from this request’s context — per-row on lists). The empty string and the legacy general / null aliases are rejected (400). Missing buckets read as 0.

spaceReputationDescendants · boolean

Only honored with an explicit space <uuid>. When true, spaceReputation is the subtree sum — the space plus all of its descendants (the root space’s own bucket included). Ignored for none; not allowed with context.

Response

Returns a ChatMessage with all populated fields including reactionCounts and userReactions for the requesting user.
