Service event parameters
Service event parameters are passed in the `ServiceParameters` field of the common parameters and must be in JSON format. The following section describes the service event parameters for Business Risk Intelligence.
Note: To maximize compatibility with various input parameters, Alibaba Cloud Fraud Detection does not validate the business format of input strings. You must validate the business format of the data. For example, for the `mobile` field, you must validate that the input parameter meets the business format requirements for a mobile number. For instance, a mobile number in mainland China is an 11-digit number that starts with 1.
Field name | Field description | Data format | Sample data | Required |
|---|---|---|---|---|
mobile | The mobile number. By default, this is a mobile number in mainland China. For numbers outside mainland China, include the country or region code in the `CountryCode-MobileNumber` format. | String | Mainland China mobile number: `1381111****`. Mobile number outside mainland China: `001-718123****` | Required. Provide either `mobile` or `mobileMd5`. |
mobileMd5 | The 32-character lowercase MD5 hash of an 11-digit mobile number that starts with 1. | String | Before MD5: `1800000****`. After MD5: `e7beea81b7a03b38508428fbeeb3c69a` | Required. Provide either `mobile` or `mobileMd5`. |
Custom return parameters
In addition to the common return parameters, the Business Risk Intelligence service returns custom parameters in the `Data` field. The following interpretation of the `score` field is based on recommendations from the Alibaba Cloud risk control team. You can adapt these guidelines for your business operations.
The `score` value is returned in the `Data` parameter and ranges from 0 to 1. A higher value indicates a higher degree of risk.

0.3 (inclusive) to 0.7 (exclusive) | Medium risk | Tag for observation or require further security authentication. |
0.7 (inclusive) to 1.0 (exclusive) | High risk | Require further security authentication or restrict permissions for high-risk operations. |
The `tags` value is returned in the `Data` parameter and indicates the following risk features:
