\n

Scam Signal<\/strong><\/p>\n\n\n\n

\n

API Description<\/h4>\n\n\n\n

The \u201cScam Signal\u201d API allows businesses to protect their customers from impersonation scams, particularly Authorized Pushed Payment (APP) fraud.<\/p>\n\n\n\n

APP fraud involves a criminal tricking someone into sending them money, often through impersonating representatives from banks, government departments, or even a family member. They can also deceive a victim into making advance payments for fraudulent investments, counterfeit goods and services, or even extort money through a seemingly genuine romance or friendship.<\/p>\n\n\n\n

The Scam Signal API is not available on CAMARA. It was developed in accordance with CAMARA standards and within the framework of GSMA OPAG. To maintain the effectiveness of the API, it is stored in a private GSMA repository. Access to this repository is strictly controlled by GSMA, and any requests for access should be directed to the appropriate GSMA contact.<\/p>\n\n\n\n
