Feature Description

• This API can send one-to-one messages to up to 500 users at a time.
• Compared with the one-to-one message API, this API is more suitable for time-sensitive messages, such as marketing messages and system notifications.
• When the admin specifies an account to send messages to target accounts in batches, the recipients will see that the sender is not the admin but the account specified by the admin.
• This API does not trigger callback requests.
• This API does not check whether the sender and the recipient are friends (nor does it check the blocklist) or whether the recipient is muted.

When the server-end integrated RESTful API is used to send messages in batches, you can determine whether to synchronize the messages to the sender (admin account or account specified by the admin). The synchronization methods include online terminals and the roaming server. The RESTful API provides the SyncOtherMachine parameter to determine whether to synchronize the messages. For details, see “Sample request packet”.

Here, we use sending text messages as an example. To send messages of other types, set MsgBody to the corresponding message type. For details, see Message Format Description.

Admin sends messages to target accounts in batches

If you do not want to synchronize messages to From_Account, set SyncOtherMachine to 2.
To synchronize messages to From_Account, set SyncOtherMachine to 1.

{
    "SyncOtherMachine": 2, // Messages are not synchronized to the sender.
    "To_Account": [ // List of target accounts
        "bonnie",
        "rong"
    ],
    "MsgRandom": 19901224, // Message random number
    "MsgBody": [ // Message
        {
            "MsgType": "TIMTextElem", // Message type. **TIMTextElem** indicates text messages.
            "MsgContent": {
                "Text": "hi, beauty" // Message text
            }
        }
    ]
}

Admin specifies an account to send messages to target accounts in batches and sets offline information push

From_Account is the sender specified by the admin. The recipients will see From_Account instead of the admin account. The following JSON request indicates that dave sends a message to the accounts bonnie and rong. When bonnie and rong receive the message, the message sender they see is dave.

If you do not want to synchronize messages to From_Account, set SyncOtherMachine to 2.
To synchronize messages to From_Account, set SyncOtherMachine to 1.

{
    "SyncOtherMachine": 1, // Messages are synchronized to the sender.
    "From_Account": "dave",
    "To_Account": [
        "bonnie",
        "rong"
    ],
    "MsgRandom": 19901224,
    "MsgBody": [
        {
            "MsgType": "TIMTextElem",
            "MsgContent": {
                "Text": "hi, beauty"
            }
        }
    ],
    "OfflinePushInfo": {
        "PushFlag": 0,
        "Desc": "Offline push content",
        "Ext": "This is the passthrough content",
        "AndroidInfo": {
            "Sound": "android.mp3"
        },
        "ApnsInfo": {
            "Sound": "apns.mp3",
            "BadgeMode": 1, // The default value is 0, indicating that a message is counted. The value 1 indicates that the message is not counted, that is, the icon number in the upper right corner does not increase by one.
            "Title":"apns title", // apns title
            "SubTitle":"apns subtitle", // apns subtitle
            "Image":"www.image.com" // image url
        }
    }
}
