    Feature Description

    You can implement the feature of merging and forwarding messages as provided by WeChat in the following steps:
    1. Create a merged message based on the list of original messages.
    2. Send the merged message to the peer end.
    3. The peer end receives the merged message and parses the list of original messages.
    The title and digest are needed to display the merged message:
    Merge and Forward
    Display of Merged Message
    Click Merged Message to Download Message List for Display

    Merging and Forwarding Messages

    Creating and sending a merged message

    A merged message can be created by setting the message list along with the merged message title and digest. The process is as follows:
    1. Call the createMergerMessage API (Details) to create a merged message. The list of original messages as well as the merged message title and digest also need to be set.
    List of IDs of original messages
    List of IDs of original messages to be merged and forwarded
    Title of the merged message, such as "Chat History of xixiyah and Hello"
    Digest list
    Digest list of the merged message. The original message digests need to be displayed for the merged message, which will be unfolded after the user clicks the cell.
    Compatibility text message
    If the SDK on an early version does not support the merged message, the user will receive a text message with the content compatibleText by default.
    Below is the sample code for creating and sending a merged message:
    // List of messages to be forwarded, which can contain merged messages but not group tips
    const msgIDList = ["msgid1", "msgid2"];
    const title = "Chat between user1 and user2";// Combined message title
    const abstractList = ["user1:hello", "user2:hello"]; // Digest list of the merged message
    const compatibleText = "The current version does not support the message"; // Compatibility text of the merged message. If the SDK on an early version does not support the merged message, the user will receive a text message with the content `compatibleText` by default.
    const createMergerMessageResult =
    await TencentImSDKPlugin.v2TIMManager
    title, // Title of the merged message
    abstractList, // Digest list of the merged message
    if (createMergerMessageResult.code == 0) {
    id: createMergerMessageResult.data.id,
    receiver: "",
    groupID: "",

    Receiving a merged message

    Adding a listener

    The receiver calls addAdvancedMsgListener (Details) to add the advanced message listener. We recommend it be called early, such as after the chat page is initialized, to ensure timely message receiving in the application.
    Below is the sample code:

    Parsing a message

    After the listener is added, the receiver will receive the merged message V2TimMessage in onRecvNewMessage. You can use the merged message element V2TimMergerElem (Details) to get the title and abstractList for UI display. Then, when the user clicks the merged message, you can call the downloadMergerMessage (Details) to download the merged message list for UI display.
    Below is the sample code:
    if(message.elemType == MessageElemType.V2TIM_ELEM_TYPE_MERGER){
    const download = await TencentImSDKPlugin.v2TIMManager.getMessageManager().downloadMergerMessage(message.msgID,);
    if(download.code == 0){
    const messageList = download.data;

    Forwarding Messages One by One

    To forward a single message, create a message identical to the original message through the createForwardMessage API (Details) first, and then call the sendMessage API (Details) to send the message.
    Below is the sample code:
    // Create a message with the same elements as the original message
    const createForwardMessageRes = await TencentImSDKPlugin.v2TIMManager.getMessageManager().createForwardMessage("msgid");
    // Send the message to the user `denny`
    if(createForwardMessageRes.code == 0){
    TencentImSDKPlugin.v2TIMManager.getMessageManager().sendMessage(id: createForwardMessageRes.data.id, receiver: "denny", groupID: "");
