@mention via incoming webhook in MS Teams

Question

I'm trying to mention a user from an incoming webhook.

I tried a few iterations via Postman of

{ "text": "test @user" } 

or

{ "text": "test @[email protected]" } 

but none of these seem to work. Is this simple but very important thing just not possible?

Thanks.

Answer 1

I'm afraid this isn't possible yet - the only way to do @ mentions is by using the full Bot Framework APIs.

You're not the only one to have asked for this though, so I'll get it on the backlog.

This is now supported and documented here (https://docs.microsoft.com/en-us/microsoftteams/platform/task-modules-and-cards/cards/cards-format?tabs=adaptive-md%2Cconnector-html#user-mention-in-incoming-webhook-with-adaptive-cards).

Sample:

{ "type": "message", "attachments": [     {     "contentType": "application/vnd.microsoft.card.adaptive",     "content": {         "type": "AdaptiveCard",         "body": [             {                 "type": "TextBlock",                 "size": "Medium",                 "weight": "Bolder",                 "text": "Sample Adaptive Card with User Mention"             },             {                 "type": "TextBlock",                 "text": "Hi <at>Adele UPN</at>, <at>Adele AAD</at>"             }         ],         "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",         "version": "1.0",         "msteams": {             "entities": [                 {                     "type": "mention",                     "text": "<at>Adele UPN</at>",                     "mentioned": {                       "id": "[email protected]",                       "name": "Adele Vance"                     }                   },                   {                     "type": "mention",                     "text": "<at>Adele AAD</at>",                     "mentioned": {                       "id": "87d349ed-44d7-43e1-9a83-5f2406dee5bd",                       "name": "Adele Vance"                     }                   }             ]         }     } }] 

}
