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

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:

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!
