# Batch add project members

`POST /v1/projects/{projectId}/members/batch`

Adds multiple members to a project in a single operation. This is useful for bulk imports or when setting up a new project with multiple team members. All members must already be part of the associated team if the project belongs to a team. If any member in the batch fails validation, the entire operation will fail.

    - `manager` boolean
    - `member` boolean
    - `managerOrOwner` boolean
