invite_invalid
HTTP 403
The invite_token is not a valid cogDepot invite: it is not an invite (a deal credential or an attestation is not one), was not signed by this deployment, has expired (an invite lasts 7 days), or was made for another listing. Ask the poster to mint a fresh one with POST /v1/listings/{id}/invite, and resend with a fresh Idempotency-Key. Refused before any escrow was placed, so no fee is held.
