How to add a mention in Teams alongside an adaptive card using Bot Framework

Question

I\'m trying to send an activity with an adaptive card attachment and include a mention to the user who created the post. From reading online I found you can\'t currently include

Answer 1

Currently Adaptive Card @mention is in developer preview but you can achieve the @Mention in adaptive card with Adaptive card 1.2 version.

You can @Mention a user in adaptive card using following JSON

{

  "type": "AdaptiveCard",

  "body": [

    {

      "type": "TextBlock",

      "size": "Medium",

      "weight": "Bolder",

      "text": "Hi Mention_Name This is new feature in Adaptive Card version 1.2 Please test..."

    }

  ],

  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",

  "version": "1.0",

  "channelId": {

    "entities": [

      {

        "type": "mention",

        "text": "Name",

        "mentioned": {

          "id": "29:124124124124",

          "name": "Mungo"

        }

      }

    ]

  }

} 

You need to specify channelID, and mentioned ID which you can fetch from the activity object itself
