inv_*) asks someone to join your Party. It’s how a business brings teammates into your party: same wallets, same agents, each person under their own login. A customer invitation (adi_*) connects an agent to another party; a party invitation adds a person to yours. Send one with POST /party-invitations.
Lifecycle
Each invitation names an email and the role granted on acceptance:ADMIN or MEMBER. ADMIN holds every permission; MEMBER is read-only. A party has exactly one owner, set when the party is created, so OWNER can’t be granted by invitation. An invitation is PENDING until the person accepts (ACCEPTED) or declines (DECLINED), or you revoke it (REVOKED) with DELETE /party-invitations/{invitationId}. Once accepted, the person appears among your party’s members.
