Configuring Message Extension for a Group Message

Feature Overview

App admins and group members can configure message extension for common group messages. Message extension is a set of custom key-value pairs.
Note:
To use this feature, you need to purchase the Ultimate edition and enable the Set message extension feature on the Login and Message page in the Chat console.
Up to 300 key-value pairs can be set for each group message.
For group messages for which key-value pairs are set, they need to be specified to support message extension when being sent. For operation details, see Sending Ordinary Messages in a Group.

Sample request

Basic format
Configure message extensions for the group message whose MsgSeq is 158:
{
    "GroupId": "@TGS#1YMVAB3IZ",
    "MsgSeq": 158,
    "OperateType": 1,
    "ExtensionList": [
        {"Key": "key1", "Value": "value1", "Seq": 0},
        {"Key": "key2", "Value": "value2", "Seq": 0},
    ]
}
Delete message extensions for the group message whose MsgSeq is 158:

    "GroupId": "@TGS#1YMVAB3IZ",
    "MsgSeq": 158,
    "OperateType": 2,
    "ExtensionList": [
        {"Key": "key1", "Value": "", "Seq": 1}
    ]
}

}

Request fields

Field
Type
Required
Description
GroupId
String
Yes
Group ID
MsgSeq
Integer
Yes
Seq of the group message to be configured
OperateType
Integer
Yes
1: Setting key-value pairs for a message; 2: Deleting certain key-value pairs for a message; 3: Clearing all key-value pairs for a message
ExtensionList
Array
Yes (when OperateType is 1 or 2)
Up to 20 key-value pairs can be set or deleted per request
Fields of the objects in ExtensionList are described as follows:
Field
Type
Required
Description
Key
String
Yes
Key in a key-value pair, which can be up to 100 bytes
Value
String
Yes
Value in a key-value pair, which can be up to 1,000 bytes
Seq
Integer
Yes (when the API is not called by an app admin)
Version number of the current key-value pair. Seq is 0 when the API is called by a group member to configure a key-value pair for the first time and is 1 when the configuration is successful. For subsequent key-value pair configuration, the latest Seq of the key-value pair needs to be passed back to the backend, which then checks whether the key-value pair has been modified by others. If the Seq does not match the key-value pair, the configuration fails, and an error code is returned. The backend does not verify the Seq when the API is called by an app admin.
