Will Conversation id in bot message change?

Question

I want to send something to a Teams chat by bot when my service receive message.
As we know, when user send @Bot in a one-to-one chat, we will receive an composeExtension message, we can get the conversation id in the message and response the event by conversation id.

But without any request, what should i do? I know that I can create a conversation in channel by channel id or create a conversation in user bot chat. But if i want to send proactive message to a chat or group chat, what should i do?

I found that the conversation id is same as groupChat id (id from graph api response), what's more, it also is same as channelData.setting.selectedChannel.id in installationUpdate message.
I wonder if they are related or same, and will the conversation id change in the future. If it doesn't change, can I store it to my database and use it to send proactive messages.

Please help
Thanks

Answer 1

Use either the conversationReference object or conversationId and tenantId to send the message. You can get this ID by either creating the conversation or storing it from any activity sent to you from that context.

You must only create the conversation once and store the conversationId value or conversationReference object", so we have to store the conversation id if we want to use it
