    Domain name for API request: faceid.tencentcloudapi.com.

    This API is used to generate an appropriate light sequence based on the information collected by the liveness comparison (reflection-based) SDK and pass the light sequence into the SDK to start the identity verification process.
    The data generated with the SDK must be stored in COS, and the region of the COS bucket must be same as that of requests made with this API. We recommend that you pass resources with upload link APIs.

    A maximum of 5 requests can be initiated per second for this API.
