Using Teams workflows to automatically post an Adaptive Card in a channel

Question

Hi team!

My situation is as follows: I set up a python application which will dynamically generate a JSON file upon some trigger, the JSON template looks like the following:

{
  "type": "AdaptiveCard",
  "attachments": [       
	{         
		"$$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
        "type": "AdaptiveCard",
        "contentType": "AdaptiveCard",
        "content": {

        },
        "version": "1.5",
        "body": [
          {
            "type": "TextBlock",
            "text": "${releaseTitle}",
            "weight": "bolder",
          	"size": "large"
          },
          {
            "type": "TextBlock",
            "text": "${description}",
            "wrap": true
          }
        ] 
      }
    ]
}

The JSON then gets templated correctly (I have triple checked the output, the double $ sign is to escape the $ sign itself in python templating). This is then sent as the body of a POST request to a Teams webhook, which has the following flow:

When I activate the request, it is successfully received and triggered, only that the card, when posted, is empty, without the text block specified in the request. Is there a different way of achieving the posting of a dynamically generated adaptive card?

Hi @Vanja Stojanović

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is related to Teams Development which is not in our support scope. To better help you solve your problem, please add the Teams Development tag to your post. The following suggestion is just for your reference:

Please make sure the Json format is correct. Please include the body field and version field in the Content field.

Use the incoming webhook to send adaptive cards. The Json format should be as follows:

{
       "type":"message",
       "attachments":[
          {
             "contentType":"application/vnd.microsoft.card.adaptive",
             "contentUrl":null,
             "content":{
                "$schema":"http://adaptivecards.io/schemas/adaptive-card.json",
                "type":"AdaptiveCard",
                "version":"1.2",
                "body":[
                    {
                    "type": "TextBlock",
                    "text": "For Samples and Templates, see [https://adaptivecards.io/samples](https://adaptivecards.io/samples)"
                    }
                ]
             }
          }
       ]
    }
