Using Flow to send or mention Adaptive card to multiple users

I have setup a few adaptive cards and the action "Post your own adaptive card as the Flow bot to a user" seems to be only capable of sending to a single user email, at least I was not able to get it to send when entering multiple emails seperated by a ; or , If anyone knows how to send to multiple users I woudl be very interested in knowing how.

I also use the same Adaptive cards using the action "Post your own adaptive card as the Flow bot to a channel" and the following

link indicates you can use <at>email<at> to create mentions and this seems to work with the actions that do not use an adaptive card and post to a channel. I tried placing <at>email<at> in a few locations within the structured adaptive card however it would either break the adaptive card or simply not work. Has anyone figured out how to use the mentions with the adaptive card?

I am simply trying to find a method to send the adaptive cards to multiple users directly and or through mentions. Thanks

Hi @Dudditz ,

Unfortunately, the Recipient field of Post your own adaptive card as the Flow bot to a user action can only be filled with a single email address.

The intent here is to send the message to a single user, you can get the requirements of this parameter from the hint.

If you want to send multiple users, please try the following method.

The specified user's email addresses are first stored in an array variable, then the array is traversed and the message is sent to multiple users.

That worked great, thank you very much for the suggestion.

Any idea if its possible to use the <at>email<at> to mention multiple people as this approach would be posting the adaptive card to a channel and than mentioning multiple instead of sending multiple people direct messages.

So it turns out I spoke to soon. When I attached the flow to my powerapp which delivers the email address in the following format.
"email@domain.com", "email@domain.com"

An error is displayed more or less indicating powerapps does not support the connection of Ask in power apps directly to a variable. This error is due to the fact my "Ask in Powerapps" is the value in the Initialize Variable field. I am testing having a compose before the variable which seems to have made progress. See images.

Not suprisingly it fails as it looks like the email address is not correct which is now coming in with surronding \email\ slashes. Is this the best way to proceed with adding the compose before the variable? If so any guidance on how to remove the \ slashes woudl be apreciated.

Hi @v-bacao-msft and @Dudditz can you please help. When I do this, it resolves the problem with sending multiple approval request at the same time BUT I am not able to respond because adaptive card gives the error. What should I do?

It may not be the best solution but what I did is to create another action as per below:

Just copy/paste the whole JSON code and just change the email

Thanks, works like a charm. Only thing is that I would really like it to send it out to about 1000 employees. Is it possible to get the email addresses from azure AD or something? Or connect it with an excel sheet?

@mharst You can get the emails by using Office 365 Users connector and if you want to just post the adaptive card without waiting for anyone's response you can do it just set the concurrency control of your Apply to each action to 50. It will take longer to post it to that number of people but it should work. Good luck
