Mentioning a Channel in Teams using Flow

[jonathancavey]

Hello, I am trying to post a message to a Teams Channel and '@' the channel in the message. 
I have accomplished this using the 'Invoke a HTTP Request' and following the steps found here: http://www.expiscornovus.com/2019/05/29/mention-a-channel-with-flow/

The problem I am running into is that these messages post as coming from a user (me)
I would like to post and '@' the channel from a bot / adaptive card. 

Does anyone know if this is possible, and if so how to?

Hi!

Did you consider the new action block for this purpose?

https://docs.microsoft.com/en-us/connectors/teams/#get-@mention-token-for-a-user

Havent tested myself yet, but hope this helps

@efialttes I am not sure if that will work, could you explain a little more? 
I have it working posting from a user, but I want it to come from a bot. So I have the IDs and all of that.

Hi!

According to this excellent article, it seems you can also use it not only in conventional posts but also inside Adaptive Cards

• Post a message (V3)
• Post a reply to a message (V2)
• Post your own adaptive card as the Flow bot to a channel
• Post an Adaptive Card to a Teams channel and wait for a response

Hope this helps

@efialttes I am attempting to '@' a channel not a user

[efialttes]

OMG! sorry for your time testing my suggestion, and let's hope somebody else can point you to a good solution!

[jonathancavey]

Yeah, I can '@' the channel. But it is posting from a user profile. I would like it post from a bot/adaptive card.

Thank you for reaching out

Wait wait wait... did you try invoking the Graph API? I am afraid the action block is premium.

THere is also a workaround published by John Liu some time ago, not sure if it is still working
