# Confirm buyer information

> Record that the material you requested from the buyer arrived, unblocking the account-setup case

`POST /api/v2/storefront/account-mappings/information-requests/{requestId}/confirm`

The buyer opening your launch link is not proof that anything arrived — a
person can open a link and never submit the form behind it. This call is your
explicit statement that the requested material showed up in your process
(the completed form, the signed contract, the reply email). It is the only
thing that unblocks the case.

Once confirmed, the account-setup case returns to your review queue with
`blockedOnParty: null`, and you decide it the same way you decide any other
pending request — accept, link to an existing account, or reject.
