Mastercard Benefit Allocation Service is one of 249 APIs that [Mastercard](https://apis.io/providers/mastercard/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Benefits, Card Management, and Issuers. The published artifact set on APIs.io includes API documentation, code examples, and a support channel.

The Benefit Allocation Service (BAS) allows issuers to efficiently manage cardholder value propositions in real-time. It enables the assignment and replacement of benefits, the freezing and unfreezing of cards, and the complete replacement of cards. Historically, benefits were assigned using a one-size-fits-all approach, limited by batch processing, which delayed critical changes and fragmented card management.
