# Update the group membership of multiple users at once.

`POST http://localhost:8000/{project_id}/groups/memberships/`

Update the group membership of multiple users at once.

Users and groups as well as their memberships are global, therefore this
action requires either superuser status or project tokens need to be in
use. If the latter is the case, the requesting user is expected to have
a) admin permission in the current project and is b) only allowed to
change users and groups visible to them.

## Path parameters

- `project_id` string, required

## Response `201`

Created
