## Data Sharing Between Customer and Mastercard {#data-sharing-between-customer-and-mastercard}

The data sharing flow shows a high-level data flow between the customer and Mastercard for data sharing. It applies to Merchants and any of their partners, such as fraud service providers, payment service providers, and, or, acquirers.
Note: The data sharing flow is only available for customers accepted into the pilot and who have agreed to the underlying terms and conditions for data sharing during the Developer Zone project creation.
