Sale card mapping notification

Introduction

Sale card mapping notification is initiated through HTTPS POST request by using URLs and the parameters.

Card mapping notification is used to allow Consumer credentials (phone, email, billing address, twitter name, etc) for mapping to card data. Card mappings can be used later in transfer or sale transactions instead of card numbers and other cardholder information. Billblend sends Sale card mapping notification request to Connecting Party’s server/proxy with created on its side card reference – {serverCardId}.

Connecting Party’s server maps this {serverCardId} to {clientCardId}, created on its side. This {clientCardId} can then be mapped in Connecting Party’s app or on Connecting Party’s server to any Consumer’s data from the initial Perform sale request. This allows Connecting Party’s app to process sale or transfer transactions by Consumer’s email, phone number, etc.

{uniqueReferenceCardId} remains the same if Consumer makes another transaction with the same card number but different expiry date, for example. It can be used by Connecting Party for loyalty programs or fraud control.

Connecting Party’s app makes new sale requests using {clientCardId} instead of source card data. Billblend sends this {clientCardId} to Connecting Party’s server in “Check sale request” and gets mapped to it {serverCardId} in “Check sale response” from Connecting Party’s server, which is used to continue the processing of this transaction.

{serverCardId} of source or verified card can be used for new sale transactions and both as source or destination for new transfer transactions.
