Recalling One-to-One Messages

Feature Overview

This API enables administrators to recall one-to-one messages.
This API can recall all one-to-one messages, including those sent by clients or by the v4/openim/sendmsg and v4/openim/batchsendmsg RESTful APIs.
To recall one-to-one messages sent by clients, you can enable the C2C.CallbackBeforeSendMsg or C2C.CallbackAfterSendMsg callback API. Record the MsgKey of each one-to-one message via the callback API, and enter it in the MsgKey field of this API to recall the message. You can also use the v4/openim/admin_getroammsg API to query the MsgKey of the one-to-one message to be recalled, and enter it in the MsgKey field of this API to recall the message.
The MsgKey field in the responses to the v4/openim/sendmsg and v4/openim/batchsendmsg API calls is required to recall the one-to-one messages sent via these two APIs.
Once a one-to-one message is recalled by this API, it is recalled from offline storage, roaming storage, and the local cache of the sender’s and recipient’s clients.
This API can recall one-to-one messages sent at any time. There’s no time limit.
Note
Please note that one-to-one messages recalled by this API cannot be restored.
