In card payments, an information request is another name for a retrieval request: a request sent by a card issuer, through the card network and the acquirer, asking the merchant to provide a copy of the sales receipt or other documentation for a transaction. The main entry explains how retrieval requests work and why responding matters.
Issuers send these requests when a cardholder does not recognise a charge or when the issuer needs more detail before deciding whether to raise a chargeback. Different networks and processors use different names: Visa's dispute process uses the term request for information, while acquirers' portals may label the same step a copy request or retrieval. A retrieval fee may be charged to the merchant.
Responding quickly with clear information, such as an itemised receipt and delivery details, can prevent a formal dispute. In other contexts, such as banking compliance, "information request" has its own meanings, for example a request from a correspondent bank for details of a payment it is screening, which is unrelated to card disputes. Handling both kinds is part of wider dispute management and compliance work.
