CENTRALIZED SYSTEM FOR DATA RETRIEVAL

This disclosure describes, in part, techniques for storing transaction data at a central service, and techniques for querying information associated with the data from the central service when authorizing payment instruments for transactions. For instance, a central service may receive historical transaction data from multiple payment services that authorize payment instruments for merchants, and then store the historical transaction data in one or more databases. A payment service may then receive a request to authorize a payment instrument for a transaction between a merchant and a customer. Based on receiving the request, the payment service can send the central service a message that includes a query for information associated with historical transaction data corresponding to the payment instrument. In response, the payment service can receive the information from the central service and authorize the payment instrument using the information.
