Teams Webhooks moving from O365 Connectors to Workflows (Power Automate)

[jd-1607]

Hey all,

Has anyone had any luck in migrating from an O365 connector to the new Workflows method for webhooks?
See this for info:

I tried this today and could not get it  to work ☹️

Here is the error I am getting on the Microsoft Flow Side

Action 'Send_each_adaptive_card' failed: The execution of template action 'Send_each_adaptive_card' failed: the result of the evaluation of 'foreach' expression '@triggerOutputs()?['body']?['attachments']' is of type 'Null'. The result must be a valid array.

The Flow template that I used

Below links are likely useful in getting this working. I will play more with this when time permit.

I ended up just parsing the json payload and formatting a simple message to the channel instead. I couldn't get the Adaptive cards working.

Upload a sample payload from the Meraki webpage (I used the Meraki template because it was the most universal)

Convert to your local timezone

Prepare the message:

Made the device URL the hyperlink:

Looks like this:

Hello,

I have managed to get this working using this link - https://support.microsoft.com/en-us/office/create-incoming-webhooks-with-workflows-for-microsoft-tea...

Follow the instructions for 'Set up an incoming webhook workflow from a template'. 

Once that's done you need to create a new template in the Meraki dashboard under the API & webhooks sections (organization wide).

Select Webhooks and then templates - 'create template' 

give it a name and then paste the json code into the liquid body section and click save.

once this is working you can add more lines:

It's quite basic but it does the job, next I will try to get the actions working so that a clickable button is created which points to the device or network that had the alert.

Now create a webhook receiver using the url that was setup in the webhook workflow and use the payload template that was just created. 

You should get something like this in teams:

Hope this is useful to somebody!

Can you paste the actual code instead of screenshot?

Sure, i wasn't sure how to do it but see below:

{
       "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": "**Meraki Alert For Organisation {{organizationName}}**"
                    },
                    {
                    "type": "TextBlock",
                    "text": "**Alert**: {{alertType}} - {{alertLevel}}"
                    },
                    {
                    "type": "TextBlock",
                    "text": "**Device**: {{deviceName}}"
                    },
                    {
                    "type": "TextBlock",
                    "text": "**When**: {{occurredAt}}"
                    }
