Channel context from command box

Occasional Contributor

I've been exploring using the command box as an entry point to my application. After the user is done, I'd like to post a card to a channel. The problem I'm running into is that I can't figure out how to get the current channel context from within the command box.


I can see that the Praise app does exactly the type of thing that I'm trying to do. If you type @Priase in the command box the app opens a task module for you to build your card. When you click "Send" it posts the card to the currently open channel.


I tried looking at the data that I get from the invoke and there doesn't appear to be anything related to the channel in there. I also tried to use the botMessagePreview response. When I did, the send button was disabled and there was an error message that said that you could only send the card in the context of a channel.


How do you get the channel context when invoked from the command box? Praise clearly has a way of doing it so it must be possible but I can't seem to figure out how.

I think I at least partially figured this out. I haven't figured out how to get the channel context from within the messaging extension itself but it looks like the javascript context does contain that information so I can use it from there.

@jasonburek - When we tried to invoke messaging extension from command box in channel scope,
we are getting context as below:

That looks similar to what I'm seeing. There is a section for "conversation" but that ID matches the From ID so it appears to be a reference to the 1:1 conversation with the user. I'm not seeing anything in there that would lead me back to the Team/Channel that's currently open.

@jasonburek - Yes , any channel related context is not available there.
