注意
This feature is currently only available in the Core SDK and Unity SDK 16.
Chat history allows for the archiving and client-side retrieval of text conversations between users. Users can look up specific conversations or view previously sent messages by all users in a conversation.
注意
Messages from blocked participants are not returned in chat history search results. A history request can come back empty if all messages in the request were from a blocked participant. In this case, the response contains a cursor indicating that there are more messages in the channel. The max argument for chat history will show fewer messages than the number requested if there is a message from a blocked user in the channel. Use the cursor value in the subsequent request to retrieve the next page of messages.
Chat history has a storage period of 7 days. If Text Evidence Management is enabled in a project, the storage period is extended to 30 days.
