Request parameters

The following table describes only the method-specific request parameters and some common request parameters. For the complete list of common request parameters, see Accessing Server APIs.

Parameter	Type	Required	Description
FromUserId	String	Yes	The ID of the message sender (registered).
GroupId	String	Yes	The group ID.
MessageType	Number	Yes	Message type. For more information about message types applicable to a group chat, see MessageBody Introduction. Signaling messages are not supported.

MessageBody	Object	Yes	Message content. For more information about the format, see MessageBody Introduction. Offline push is not supported.
SubMsgType	Number	No (Yes if `MessageType` is `200`)	Custom message type. Value range: [0,200].
SearchedContent	String	No	The searched content of the custom message. This field is required only if `MessageType` is `200` and can contain up to 64 bytes in length. This field is required to search for associated custom messages on the client.
SendMessageTime	Number	No	The Unix timestamp when the message was sent. Unit: ms. Import messages based on their sending timestamps in chronological order. If the value is set to `0` or not specified, the current time is used. If a value other than `0` is specified, it cannot be earlier than "the current time - message retention days specified in the package × 86400000" or later than the current time.

Note

The FromUserId and GroupId parameters can contain only digits, letters, and the following characters: '!', '#', '$', '%', '&', '(', ')', '+', '-', ':', ';', '<', '=', '.', '>', '?', '@', '[', ']', '^', '_', ' ', '{', '}', '|', '~'.

Note

We recommend that you use the SDK of the latest version for better experience.
To receive a text message whose MessageType is 1, the version of the receiving ZIM SDK needs to be 2.7.0 or later.
To send and receive a custom message whose MessageType is 200, the version of the sending and receiving ZIM SDKs needs to be 2.8.0 or later.
If the version of the receiving ZIM SDK is 2.0.0 or later but earlier than 2.8.0, the ZIM SDK can receive a custom message but will identify the message type as unknown. In addition, it cannot obtain the message content. To obtain the message content, upgrade the ZIM SDK to 2.8.0 or later.
If the version of the receiving ZIM SDK is 1.x.x, the ZIM SDK cannot receive a custom message and identify the message type as unknown.
