Members overview ​

A member record is the link between a user and a workspace or a project. Reading a roster answers two questions: who belongs here, and in what role.

v2 returns the membership, not the user. Every row is three fields — the membership's own id, the member_id of the user it points at, and the role that user holds in this context. Names, emails, and avatars belong to the user, and you pull them into the same response with ?expand=member.

The member object ​

Attributes ​

  • id string (uuid)

    Unique identifier for the membership row — not for the user. The same person has one membership in the workspace and another in each project they belong to, so they have several id values but one member_id.

  • member_id string (uuid)

    The user this membership belongs to. This is the id that lines up with created_by_id on other objects, assignee_ids on work items, and actor_id in audit logs. Join on member_id, never on id.

  • role string

    The member's role in this workspace or project, expressed as a slug. It is what decides whether this person can write here at all.

    The slug is context-correct: the same person can read as member on the workspace roster and as contributor on a project roster. Nullable — null appears only on legacy rows that predate role slugs.

Roles are an open set, not an enum

The schema types role as a plain string with no enum. Built-in slugs such as owner, member, and contributor are joined by whatever custom roles the workspace has defined, each under its own slug. Match the slugs you care about and fall through gracefully on anything else — do not write an exhaustive switch.

Endpoints ​

MethodPathDescription
GET/api/v2/workspaces/{slug}/members/List workspace members
GET/api/v2/workspaces/{slug}/projects/{project_id}/members/List project members

Both endpoints return the active roster for their scope. The workspace list is the superset: a project member is always a workspace member too, so a member_id on a project roster always appears on the workspace roster as well — usually with a different role.

Members are read-only in v2. There are no v2 endpoints to invite, update, or remove a member; membership changes are made in Plane or through the v1 members endpoints.

Membership ids are not user ids ​

This is the single mistake worth designing against. Given the same person:

Rosteridmember_id
Workspace my-teamc1b7e4a9-2f66-4a1d-9c3b-7d5e2f8a1b4016c61a3a-512a-48ac-b0be-b6b46fe6f430
Project 4af68566-…067b9d2f5c81-4b73-4e60-8a1f-2c9b6d3e7f0416c61a3a-512a-48ac-b0be-b6b46fe6f430

Key your user cache on member_id. Use id only when you need to talk about the membership itself.

Expanding the user ​

Members are one of only two v2 resources that accept ?expand= — the other is work items. The single allowed value here is member.

bash
GET /api/v2/workspaces/my-team/members/?expand=member

Expansion is separate-key: member_id stays exactly where it was and a member object is added beside it. The id is never swapped for an object, so code that reads member_id keeps working whether or not the caller expanded. The expanded object carries id, display_name, avatar_url, and email.

Any other value — user, project, role — is rejected with 400 validation_error. See Expanding relations for the full contract.

Roles and errors ​

A role that is too narrow produces 403 forbidden on the write you attempted. Roles never produce a 404: a workspace or project outside your tenant returns 404 resource_not_found whether or not you would have had the role for it.

A 409 is never a role problem

If a write comes back 409 work_item_types_managed_at_workspace or work_item_types_managed_at_project, the caller's role and scopes are fine. The workspace simply manages work item types on the other surface, and the same call succeeds there. See Work item type modes.

Changed from v1 ​

  • A member row is now the membership, not a flattened user. v1 returned first_name, last_name, email, avatar, avatar_url, and display_name inline; v2 returns id, member_id, and role, and moves the user fields behind ?expand=member.
  • role is a slug string, not the numeric level v1 returned. Compare role == "member", not role >= 15.
  • Responses are paginated envelopes rather than bare arrays. See Pagination.
  • v2 exposes reads only. The v1 add, update, and remove member endpoints have no v2 equivalent yet.

See Migrating from v1 for the full list.
