# Update workspace member roles

PUT http://localhost:8080/apis/entities/v2/workspaces/{workspace}/members/{principal_id}
Content-Type: application/json

Update the roles for a workspace member.

This will revoke existing roles not in the new list and add new roles.
By default, this endpoint waits for the roles to propagate before returning.
Use `wait_role_propagation=false` to skip waiting (useful for bulk operations).

Example:

```
PUT /apis/entities/v2/workspaces/ml-team/members/user@example.com
{
    "roles": ["Viewer", "Editor"]
}
```
