This page documents the canonical HTTP contract for this endpoint.
Resolution uses the send scope: the actor must own the account, have an active send delegation, or be an admin. Read-only delegations do not qualify. For managed-fleet accounts, platform assignment/access rules still apply to admins. If a nonempty capabilities list is present, the account must include send; otherwise the endpoint returns 409. Ordinary account connection status does not have to be ready for inspection; managed-fleet accounts also require current allocation and mailbox access.
Only active (not revoked) delegations are included. The example is abbreviated; account and delegation records can contain additional fields.
