Access method for calling anti-fraud system and application server

The invention discloses an access method for calling an anti-fraud system. The method comprises the steps that APIs are configured according to the class of background data products, and the background data products of an application server are obtained through the APIs; the APIs are classified according to the class of the background data products, and the classified APIs are packaged; description documents which call the background data products are classified; an SDK module is constructed according to the packaged APIs and the classified description documents; access of the anti-fraud system is conducted according to the SDK module. The invention further provides the application server. According to the application server and the access method for calling the anti-fraud system, the technical threshold of an access party can be reduced, the access efficiency is improved, meanwhile, the APIs are packaged, a specific implementation method in a function is hidden, related algorithms areimplemented, and the saf
