Invoke a Callback After Disbanding a Group

Last updated: 2020-06-10 18:37:41

    Feature Description

    The app backend uses this callback to monitor group dismissal in real time, including recording group dismissal information in real time (for example, recording a log or synchronizing the information to other systems).

    Precautions

    • To enable this callback, you must configure the callback URL and toggle on the corresponding protocol. For details on the configuration method, see Third-Party Callback Configuration.
    • Callback direction: the IM backend initiates an HTTP POST request to the app backend.
    • After receiving the callback request, the app backend must check whether the SDKAppID contained in the request URL is consistent with its own SDKAppID.
    • For other security-related issues, see Third-Party Callback Overview: Security Considerations.

    Callback Triggering Scenarios

    • An app user dismisses a group through a client.
    • The app admin dismisses a group through a RESTful API.

    Callback Triggering Time

    The callback is triggered after a group is dismissed.

            {
                "Member_Account": "leckie"
            },
            {
                "Member_Account": "peter"
            },
            {
                "Member_Account": "bob"

        ]
    }

    Request packet fields

    Field Type Description
    CallbackCommand String The callback command.
    GroupId String The ID of the dismissed group.
    Type String The type of the dismissed group, such as Public. For details, see Group Types.
    Owner_Account String The UserID of the group owner.
    MemberList Array The member list of the dismissed group.

    Response packet example

    After recording group dismissal information, the app backend sends a callback response packet.

    {
        "ActionStatus": "OK",
        "ErrorInfo": "",
        "ErrorCode": 0
    }

    Response packet fields

    Field Type Attribute Description
    ActionStatus String Required The request processing result. OK: succeeded. FAIL: failed.
    ErrorCode Integer Required The error code. We recommend that you set this field to 0. This callback is used to notify users after the group is dismissed. The error code value does not affect the normal group dismissal process.
    ErrorInfo String Required Error information.
