    Sample requests

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

      {
      "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 packet"
              }
          },
          {

              "MsgContent": {
                  "Index": 6,
                  "Data": "abc\u0000\u0001"
              }
          }
      ],
      "OfflinePushInfo": {
          "PushFlag": 0, // Normal push
          "Desc": "Content to push offline",
          "Ext": "Passthrough content",
          "AndroidInfo": {
              "Sound": "android.mp3"
          },
          "ApnsInfo": {
              "Sound": "apns.mp3",
              "BadgeMode": 1, // If this field is left as default or is set to `0`, the message is counted. If this field is set to `1`, the message is not counted, that is, the icon number in the upper-right corner does not increase.
              "Title":"apns title", // APNs title
              "SubTitle":"apns subtitle", // APNs subtitle
              "Image":"www.image.com" // Image URL
          }
      }
      }
      
    • 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.
      "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"
              }
          }
      ]
      }
      
    • 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.
           {
               "MsgType": "TIMTextElem", // Text
               "MsgContent": {
                   "Text": "red packet"
               }
           },
           {
               "MsgType": "TIMFaceElem", // Emoji
               "MsgContent": {
                   "Index": 6,
                   "Data": "abc\u0000\u0001"
               }
           }
       ]
      }
      
    • 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,
                  "Data": "abc\u0000\u0001"
              }
          }
      ]
      }
      
    • 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"
                  }
