Inviting Members

You add collaborators to a workspace by inviting them by email. An invite is a one-time link tied to a specific email address and a specific role. The recipient signs in with that email, accepts the invite, and becomes a member — gaining access to every canvas and credential the workspace owns, bounded by the role you chose.

Who can invite

• Owners and admins can invite members as editor or viewer, and can manage existing invites and members.
• Only the owner can invite someone as an admin. An admin cannot create another admin.
• Editors and viewers cannot invite anyone.

Send an invite

1. 1

   Enter the email and pick a role

   Provide the collaborator's email and choose editor, viewer, or — if you are the owner — admin. The email is validated and normalized (trimmed and lowercased) so the same address resolves consistently.

2. 2

   An invite link is created

   BuilderStudio generates a unique invite token and an invite link. The invite is recorded as pending with an expiry. If a pending invite already exists for that email in the workspace, it is superseded — the older one is revoked so only the newest invite is live.

3. 3

   The recipient gets an email

   An invite email is sent to the address with the link. The recipient opens it, signs in with the matching email, and accepts.

4. 4

   They become a member

   On accept, a membership with the invited role is created (or, if they were already a member, their role is updated to match), and the invite is marked accepted. They now appear in the member list.

Invite lifecycle

Each invite moves through a small set of states. Only a pending, unexpired invite can be accepted.

What acceptance checks

Acceptance is deliberate about safety. The invite must exist and resolve to a single token, it must still be pending, it must not have expired, and the signed-in user's email must match the invite's email. Any mismatch is rejected with a clear reason rather than silently joining the wrong person.

Manage members and invites

• Change a role.Owners and admins can change an editor's or viewer's role; only the owner can grant or revoke admin. The owner's role cannot be changed.
• Remove a member. Owners and admins can remove members; only the owner can remove an admin, and no one can remove the owner.
• Resend or replace an invite. Sending a fresh invite to the same email revokes the previous pending one, so there is always at most one live invite per email per workspace.
