Sample requests

• Basic format
  The app admin sends ordinary group messages, and the sender is the app admin.

  {

• Specifying the message sender
  The app admin can specify a group member as the message sender in From_Account.
  After receiving the message, other members will see that the message is sent from the group member specified by the app admin.

  {
  "GroupId": "@TGS#2C5SZEAEF",
  "From_Account": "leckie", // Message sender (optional)
  "Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.

      }
  ]
  }
  

• Specifying that messages do not trigger conversation update
  If SendMsgControl is set to NoLastMsg, messages do not trigger conversation update (not available for AVChatRoom).

  {
   "GroupId": "@TGS#2C5SZEAEF",
   "Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
   "SendMsgControl":["NoLastMsg"],// Do not trigger conversation update.
   "MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
       {

           "MsgContent": {
               "Text": "red packet"

       }
   ]
  }
  

• Specifying the message priority
  You can specify the message priority. The default priority is Normal.
  There are three priority options in descending order: High, Normal, and Low. They are case-sensitive.

  {
  "GroupId": "@TGS#2C5SZEAEF",
  "Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
  "MsgPriority": "High", // Message priority
  "MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
      {
          "MsgType": "TIMTextElem", // Text
          "MsgContent": {
              "Text": "red packet"
          }
      },
      {
          "MsgType": "TIMFaceElem", // Emoji
          "MsgContent": {
              "Index": 6,

          }
      }
  ]
  }
  

• Forbidding callback for a message
  When the callback switch is turned on, users can specify ForbidCallbackControl to control whether to initiate callback for a single message. By default, callback is initiated.

  {
  "GroupId": "@TGS#2C5SZEAEF",
  "Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
  "ForbidCallbackControl":[
    "ForbidBeforeSendMsgCallback",
    "ForbidAfterSendMsgCallback"], // Callback forbidding control options
  "MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
      {
          "MsgType": "TIMTextElem", // Text
          "MsgContent": {
              "Text": "red packet"
          }
      },
      {
          "MsgType": "TIMFaceElem", // Emoji
          "MsgContent": {
              "Index": 6,
              "Data": "abc\u0000\u0001"
          }
      }
  ]
  }
  

• Sending group @ messages
  The target @ users set in the GroupAtInfo field have a one-to-one and sequential correspondence to the target @ users in the message body.

  {
    "GroupId": "@TGS#2C5SZEAEF",
    "Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
    "MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
        {
            "MsgType": "TIMTextElem", // Text
            "MsgContent": {
                "Text": "red @all @tommy @brennanli packet"
            }
        }
    ],
    // It corresponds to @all @tommy @brennanli in the text information.
    "GroupAtInfo":[
    {
        "GroupAtAllFlag":1 // `1`: @ all ; `0`: @ a certain group member
    },
    {
        "GroupAtAllFlag":0,
        "GroupAt_Account":"tommy" // @ a specific group member
    },
    {
        "GroupAtAllFlag":0,
        "GroupAt_Account":"brennanli"
    }
  ]    
  }
  

• Specifying messages for online delivery without offline or roaming retention
  If OnlineOnlyFlag in the message body is set to a value greater than 0, the message is for online delivery only, not for offline or roaming retention (not available for AVChatRoom and BChatRoom).

    {
      "GroupId": "@TGS#2C5SZEAEF",
      "Random": 8912345, // A random number. If the random numbers of two messages are the same within five minutes, they are considered to be the same message.
      "OnlineOnlyFlag": 1, // The message is for online delivery only (only online group members will receive it), not for offline or roaming retention.
      "MsgBody": [ // Message body, which consists of an element array. For details, see the field description.
          {
              "MsgType": "TIMTextElem", // Text
              "MsgContent": {
                  "Text": "red packet"
              }
          },
          {
              "MsgType": "TIMFaceElem", // Emoji
              "MsgContent": {
                  "Index": 6,
                  "Data": "abc\u0000\u0001"
