CreateGroup

Last updated: 2023-02-27 15:22:50

1. API Description

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

This API is used to create an empty group. If the group already exists, an error will be returned.
Custom description fields can be created as needed to describe persons in the group.

A maximum of 100,000 groups or 50 million faces can be created under one APPID.

The maximum number of faces that can be included in one group varies by algorithm model version (FaceModelVersion), which is 1 million for v2.0 or 3 million for v3.0.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name Required Type Description
Action Yes String Common Params. The value used for this API: CreateGroup.
Version Yes String Common Params. The value used for this API: 2020-03-03.
Region No String Common Params. This parameter is not required for this API.
GroupName Yes String Group name, which is modifiable, must be unique, and can contain 1 to 60 characters.
GroupId Yes String Group ID, which is unmodifiable, must be unique, and can contain letters, digits, and special symbols (-%@#&_) of up to 64 B.
GroupExDescriptions.N No Array of String Custom group description field that describes the person attributes in the group, which will be applied to all persons in the group.
Up to 5 ones can be created.
Each custom description field can contain 1 to 30 characters.
The custom description field must be unique in the group.
Example: if you set the "custom description field" of a group to ["student ID","employee ID","mobile number"],
then all the persons in the group will have description fields named "student ID", "employee ID", and "mobile number".
You can enter content in the corresponding field to register a person's student ID, employee ID, and mobile number.
Tag No String Group remarks, which can contain 0 to 40 characters.
FaceModelVersion No String Algorithm model version used by the Face Recognition service.

Currently, 2.0 and 3.0 are supported.

This parameter is 3.0 by default starting from April 2, 2020. If it is left empty for accounts that used this API, 2.0 will be used by default.

The parameter can be set only to 3.0 for accounts that purchase the service after November 26, 2020.

Different algorithm model versions correspond to different face recognition algorithms. The 3.0 version has a better overall effect than the legacy version and is recommended.
