Using adaptive cards

[chandrakanthkannam]

Hi,

I have tried using adaptive cards, when we use adaptivecard.NewMessage().Mention(), how can i mention custom bot which is configured with the channel I'm posting to. Please advice. Thanks

Hi @chandrakanthkannam,

In short, I don't know for sure. If it's possible using this library I'd like to showcase it to assist others with the same question in the future.

Based on earlier research, it looks like there are two ID forms supported by Microsoft Teams:

Example of an ID:

• 2b450b8e-1db6-42cb-a545-1b05eb8a358b

Example of a User Principal Name (UPN):

• [email protected]

The https://docs.microsoft.com/en-us/powershell/module/azuread/get-azureaduser?view=azureadps-2.0 doc showed how to retrieve the ID values using PowerShell cmdlets.

Some potentially relevant official documentation:

Some examples for mentioning actual users are available here:

I've not tested the steps, but this guide:

https://d365demystified.com/2021/03/17/tag-a-user-in-a-microsoft-teams-post-made-using-power-automate/

walks you through the process of getting a Mention Token for a user via Power Automate. This may work for retrieving the ID and Name values for a bot.

Once you have that, you could try mentioning the bot as you would another user.

This guide provides the steps necessary to retrieve the ID and display name for a tag:

It may be that retrieving the ID and display name for a bot is similar (haven't tested).
