Importing One-to-One Messages

Feature Overview

This API imports one-to-one chat history to Tencent Cloud Chat** in chronological order**.
It imports your messages from other instant messaging platforms to Tencent Cloud Chat in chronological order.
It updates a conversation.
It does not trigger a callback.
It deduplicates the imported messages in a one-to-one conversation based on the MsgSeq, MsgRandom, and MsgTimeStamp fields. When the values of all these three fields match their counterparts, the two messages are considered duplicates, regardless of their contents. In addition, if the MsgSeq, MsgRandom, and MsgTimeStamp fields of the two messages matches each other, but from_account and to_account are opposite, the two messages are also considered duplicates.
Imported messages will not be overwritten by the same messages from later imports.
For one-to-one messages, the MsgSeq field is specified by the user when the message is sent. Its value can be repeated. It is not generated by the backend and not globally unique. For group chat messages, the value of the MsgSeq field is generated by the backend, and each group maintains its respective MsgSeq which increases strictly from 1. For one-to-one messages, the historical messages of the same conversation are sorted by timestamp first, and then the historical messages of the same second are sorted by MsgSeq.
