Invite a member by email

Creates an invitation and, by default, emails the recipient an acceptance link; pass sendEmail: false to skip the email and deliver the returned url through your own channel. The response always includes the acceptance url. Requires a role with member management (owner or admin). The invited role defaults to full_editor and cannot be owner; invitations expire after 48 hours unless a custom expiresAt is set. Returns 409 when a pending invitation already exists for the email (pass resend: true to cancel it and issue a new one) or when the email already belongs to an organization member. List pending invitations with organizations.invitations.list.
