The new GMAP framework
Understand how Mastercard is changing fraud and dispute monitoring.
Starting in April 2027, GMAP will change how fraud, disputes, merchant performance, and portfolio exposure are monitored. Whether you are protecting a merchant account or managing portfolio-level risk, these guides will help you understand what's changing and what to do next.
Choose the resource that matches your role.
Each guide is tailored to a different audience, but both are built around the same goal: helping you understand GMAP exposure before it becomes an audit, assessment, or processing issue.

GMAP introduces a broader way to evaluate fraud and dispute activity. It does not only look at chargebacks. It also considers fraud reported to Mastercard’s Fraud & Loss Database, which means risk can build before a traditional chargeback ever appears.
GMAP combines fraud and dispute activity into a more complete risk picture.
Merchants and portfolios can be reviewed monthly, with escalating consequences when thresholds are crossed.
The strongest strategy is to understand your exposure early and reduce the fraud and disputes that create GMAP risk.
GMAP rewards prevention — not cleanup.
Once fraud or disputes are reported, the number may already be working against you. Fraud Deflect helps merchants and acquirers move upstream by preventing fraudulent transactions before they process, resolving disputes before they become chargebacks, and improving visibility into the metrics that matter.
Fraud Deflect helps identify and block high-risk activity before it becomes reported fraud.
Issuer collaboration and dispute-resolution tools help reduce the activity that feeds monitoring thresholds.
Whether you are protecting one merchant account or managing portfolio exposure, the goal is the same: reduce the fraud and disputes that drive GMAP risk.
