This document is for users who require low-latency and high-performance API access.
Region configuration
Select a region close to your server for the service API's public network address. This reduces call latency.
If your server is deployed on Alibaba Cloud, select a private network address based on your server's region. Private network calls significantly reduce end-to-end latency compared to public network calls.
The following table lists the supported regions and their configurations.
Region | regionId | Public endpoint | Private endpoint |
Shenzhen | cn-shenzhen | saf.cn-shenzhen.aliyuncs.com | saf-vpc.cn-shenzhen.aliyuncs.com |
Shanghai | cn-shanghai | saf.cn-shanghai.aliyuncs.com | saf-vpc.cn-shanghai.aliyuncs.com |
Hangzhou | cn-hangzhou | saf.cn-hangzhou.aliyuncs.com | saf-vpc.cn-hangzhou.aliyuncs.com |
Zhangjiakou | cn-zhangjiakou | saf.cn-zhangjiakou.aliyuncs.com | saf-vpc.cn-zhangjiakou.aliyuncs.com |
Beijing | cn-beijing | saf.cn-beijing.aliyuncs.com | saf-vpc.cn-beijing.aliyuncs.com |
China (Hong Kong) | cn-hongkong | saf.cn-hongkong.aliyuncs.com | saf-vpc.cn-hongkong.aliyuncs.com |
Singapore | ap-southeast-1 | saf.ap-southeast-1.aliyuncs.com | saf-vpc.ap-southeast-1.aliyuncs.com |
Call methods
You can access the Fraud Detection API in one of two ways: use the official SDK or make native HTTPS calls directly to the endpoint.
1. Access using the official SDK
Method:
DefaultProfile.addEndpoint(regionId, "saf", endPoint);Example: For a server deployed on an Alibaba Cloud ECS instance in Shanghai:
DefaultProfile.addEndpoint("cn-shanghai", "saf", "saf-vpc.cn-shanghai.aliyuncs.com");
Select a RegionId from the table based on your server's deployment location. If your server is deployed on Alibaba Cloud, use the private endpoint.
2. Call directly using the endpoint
Example: For a server deployed on an Alibaba Cloud ECS instance in Shanghai, set the API address to https://saf-vpc.cn-shanghai.aliyuncs.com.
If you cannot ping the private endpoint, confirm that your deployment environment supports VPC networks.
