Create a project member

POST/api/v2/workspaces/{slug}/projects/{project_id}/members/

Members are the people on a workspace or project, and the role each one holds. Create a project member.

Path Parameters

slug:requiredstring

The workspace slug. It appears in your Plane URLs — in https://app.plane.so/my-team/projects/, the slug is my-team.

project_id:requiredstring

The project the resource belongs to. Accepts the project UUID or its bare identifier, for example ENG.

Body Parameters

member_id:optionalstring (uuid)

Id of the related member.

role:optionalstring

Role to grant.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Unrequested keys are omitted, not returned as null. id always comes back. Pass all for every requestable field. An unknown name is a 400. See Sparse fields.

Requestable here: id, member_id, role.

expand:optionalstring

Comma-separated relations to embed: member.

Expansion is separate-key — ?expand=state keeps state_id and adds a state object next to it. ?fields= and ?expand= are independent: naming a relation in ?fields= is a 400, and expanded objects survive field filtering. See Expanding relations.
