Creating a Group

Feature Overview

This API is used by the app admin to create groups.

API Calling Description

Applicable group types

Group Type ID
RESTful API Support
Private
Yes. Same as work groups (Work) in the new version.
Public
Yes
ChatRoom
Yes. Same as meeting groups (Meeting) in the new version.
AVChatRoom
Yes. To use an audio-video group (AVChatroom), users (including the group owner) must use the SDK to request to join the group.
Community
Yes
These are the preset group types in Chat. For more information, see Group System.
Caution
If the group type is specified as audio-video group (AVChatRoom):
When creating a group of this type, the group creator cannot add users to the group. If a group member is specified during the group creation, error 10007 will be returned. Users can only request to join this type of group. If a group owner is specified, the group owner must use the SDK API to join the group every time he or she uses the group.
If the group type is specified as a type other than an audio-video group (AVChatRoom):
If neither a group owner nor a group member list is specified when the request is sent, the number of groups that can be created is unrestricted.
If a group owner or group member list is specified when the request is sent, the specified group owner or group members are automatically added to the group.
If the total number of groups in the app exceeds 100,000, certain fees will be charged. For more information, see Pricing.
The number of groups that a user can join at the same time is limited. If the number is reached, joining or creating a group will fail. For more information, see Pricing.

Error Codes

The returned HTTP status code for this API is always 200 unless a network error (such as error 502) occurs. The specific error code and details can be found in the response fields ErrorCode and ErrorInfo respectively. For public error codes (60000 to 79999), see Error Codes. The following table describes the error codes specific to this API:
Error Code
Description
10002
Internal server error. Try again.
10003
Invalid request command word.
10004
Invalid parameter. Check the error description and fix the issue.
10005
The number of members imported in the request packet exceeds 100. Reduce the number of members imported in the MemberList parameter.
10006
The operation exceeds the frequency limit. Please reduce the call frequency. This error is usually caused by too much net group increase in a single day or too frequent calls to obtain all groups in the app.
10007
Insufficient operation permission. Check the request parameters based on the error information. For example, the specified group type does not allow adding members but MemberList was specified in the request.
10008
The request is invalid, probably because verification of the signing information in the request failed. Please try again or submit a ticket.
10016
The app backend rejected this operation through a webhook. Check the returned value of your wehook "Before a group is created".
10021
The group ID has already been used by another user. Select another group ID.
10025
You have already used this group ID. Disband the existing group first or select another group ID.
10036
The number of audio-video groups (AVChatRoom) created exceeds the limit. Delete some of the groups or purchase an upgrade by referring to Pricing.
10037
The request specifies Owner_Account, but the number of groups that the group owner has created or joined exceeds the limit. The group owner needs to leave some groups first or refer to Pricing to purchase an upgrade.
10038
The number of members imported in the request packet exceeds the limit. Reduce the number of members imported in the MemberList parameter or purchase an upgrade by referring to Pricing.
10058
