A consumer uses a web client to transmit purchase information associated with a transaction to a merchant server. The purchase information is transmitted via a web acceleration server. The web acceleration server identifies enhanced authorization data associated with the transaction. The web acceleration server creates a pseudo authorization message. The web acceleration server transmits the pseudo authorization message to a transaction account issuer. The merchant server transmits an authorization request to the transaction account issuer. The transaction account issuer determines that the authorization request and the pseudo authorization message are associated with the same transaction. The transaction account issuer merges the authorization request and the pseudo authorization message and performs a fraud analysis. The transaction account issuer transmits an authorization response to the merchant.
