Seeking help on how to obtain synchronized conversations.

[super-zzc]

I am seeking help because I don't know how to retrieve the conversation list. Using client.Store.Contacts.GetAllContacts() and client.GetJoinedGroups() only allows me to get the list of added contacts and groups, but I am unable to obtain conversations when I haven't added the contact and yet have a conversation with them. I'm not sure how to get the synchronized conversation list.

As far as I know there is no interface like that. You have to create and hold conversations on your application side. You can reconstruct them while parsing all incoming messages (either coming from history sync or live).

Keep in mind that newly created conversations from your application side have to be threated separately.

据我所知，没有这样的界面。您必须在应用程序端创建并保持对话。您可以在解析所有传入消息（来自历史同步或实时消息）时重建它们。

请记住，从应用程序端新创建的对话必须受到单独威胁。

Hi, thank you for your response. On the web version of WhatsApp and the mobile app, I can initiate conversations with people who are not added as contacts without any issues. I'm wondering if whatsmeow supports retrieving such conversation lists. Are you saying that I must engage in a conversation with the other party using whatsmeow and then rely on the historical messages to recreate it?

Yes, you can create conversations with people that are not in your contacts. But maybe you should check if they are on WhatsApp first.

If you connect your session the first time you get all messages synced and should store them.

序上，我可以毫无问题地与未添加为联系人的人发起对话。我想知道 whatsmeow 是否支持检索此类对话列表。您是说我必须使用

Hello, I need to maintain my login on whatsmeow to receive conversations from non-contacts either when they initiate the conversation with me or when I initiate it with them. For past conversations with non-contacts, I am unable to retrieve them, correct? It is only after one party initiates the conversation that I can then obtain the chat history.

There is no difference if it is a contact or a non-contact.

The flow is like this:
The first time after you scan the QR code to login (or type in the login code), you will receive all past messages in the history sync events. You need to save them in your own database.

While you save them, it's good practice to save them in a message table and in a conversation table. For every first message of a distinct JID you create a new conversation.
