Edit a message

Description

The ZIM server supports developers in editing a message sent in a one-to-one or group conversation.

After a message is edited, the message sent callback is triggered. At the same time, the message receiver can receive the message edited notification through the following ZIM SDK callback interface.

iOS	Android	macOS
messageEdited	onMessageEdited	messageEdited

Windows	Web	小程序
onMessageEdited	messageEdited	messageEdited

Flutter	uni-app	HarmonyOS
onMessageEdited	messageEdited	messageEdited

React Native
messageEdited

Note

By default, only messages sent within the last 24 hours can be edited. For editing older messages, please contact ZEGOCLOUD technical support for configuration.

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 user ID of the message editor. Note When editing group messages, this user must be a member of the target group.
SenderId	String	Yes	The ID of the message sender. This field is required when editing a one-to-one message. This field is optional when editing a group message.
ConvId	String	Yes	The conversation ID. When editing a one-to-one message, fill in the userID of the other participant. When editing a group message, fill in the groupID of the target group.
MsgType	Number	Yes	The message type. Supported values: 1: Text. 10: Combined. 200: Custom.
ConvMsgSeq	Number	Yes	The message sequence. How to obtain: If you need to edit a one-to-one conversation message sent by the client, retrieve MsgSeq via the Callback on message sent. If you need to edit a one-to-one message sent by the server API Send a one-to-one message, get MsgSeq from the API response data. If you need to edit a group conversation message sent by the server API Send group messages, get MsgSeq from the API response data.
EditType	Number	Yes	The edit type. Supported values: 1: EM_MSG (edit the content of the message), which modifies the `Message` field in `MessageBody`; in this case, `Message` cannot be empty. 2: EM_PAYLOAD (edit the extended content of the message), which modifies the `ExtendedData` field in `MessageBody`; in this case, `ExtendedData` can be empty. 4: EM_AT (edit the reminder attributes of the message), which modifies `AtListInfo` or `IsAtAll`; in this case, both `AtListInfo` and `IsAtAll` can be empty. 8: EM_AT_ALL (edit whether to remind all users), which modifies `IsAtAll`. 16: EM_SUBMSGTYPE (edit the type of custom message), which modifies `subMsgType`; in this case, `MsgType` must be `200`. You can perform bitwise operations on any of the above values to indicate editing multiple properties of the message simultaneously, e.g., 3: select both EM_MSG and EM_PAYLOAD to modify the `Message` and `ExtendedData` fields in `MessageBody`.
MessageBody	Object	No	Required when `EditType` includes EM_MSG or EM_PAYLOAD. Please refer to the MessageBody Description for the structure of this parameter, including the `Message` and `ExtendedData` field descriptions for text messages, combined messages, and custom messages.
AtListInfo	Object	No	The list of users to be mentioned. Required when `EditType` includes EM_AT. Please refer to the AtListInfo Description for the structure of this parameter.
IsAtAll	Bool	No	Whether all users are to be mentioned. Required when `EditType` includes EM_AT_ALL.
SubMsgType	Number	No	The type of custom message defined by you, with a value range of [0, 200]. Required when `EditType` includes EM_SUBMSGTYPE.
