Help: chatGuid + and - meaning

[User8395]

When sending a message via the REST API, the chatGuid is as follows

"chatGuid": "iMessage;-;email@email.com"

My question is why is there a minus in the middle and sometimes a plus, and why is the "Chat does not exist" error thrown when using a plus instead of a minus?

So i dont think I've personally seen a + before in the chatGuid, would u happen to have an example of this? (not a bb dev though so I have WAY WAY less knowledge abt how imessage works)

DMs will be iMessage;-;{address} while group chats are iMessage;+;chat{number}

Can you give an example of sending to a group with 1234567890, bob@bob.com, and 6666666666?

I guess then you would get the chatguid from that group (I usually get it through a new-message webphook) and then use it

How would that work? Does it show the guid when listing chats?

Yeah get the chat guid from an API call or something. If you have a group chat name, it'll be easily identifiable from the chat endpoint

I setup the new-message webhook and then an HTTP server (there should be an example in python somewhere) then I would wait for a message from that group chat. Once it arrives look at the logs and see what the chatGUID is.
There's probably a different way to do it (maybe you could send a message to the group chat and use message updates
