How do I send an SMS to an Azure Action Group with an Azure Logic App (with or without ACS)

Question

How do I integrate an Azure Action Group into the Azure Communication Service Send SMS action or HTTP Post Action to send a preconfigured SMS message to the phone numbers in the Action Group when the Logic App is triggered from IOT Central.

I first tried using the HTTP action with a POST method and I keep getting a 404 error. I have validated authentication prior to sending the POST request to the Action group. The error I get from the HTTP action in the run history indicates that I have an incorrect Webhook URL for the Action group in question. I copied and pasted the URL from the action group into the HTTP action so it should be correct. Any thoughts on where to retrieve the webhook URL for the action group is appreciated. Or maybe that is not the error and I have gone down the wrong rabbit hole.

What we are trying now as an alternative is the Send SMS action using an Azure Communication Service. This is functioning very well however we have no way of sending the SMS message to the members of the action group. The Action in the Logic app requires that we add each individual phone number within the Logic App Action instead of sending the SMS message to the members of the already setup Azure Action Group. We would prefer to use the Action group as this is easier to maintain the group members with the Action Group instead of manual entry in the Logic app. We have many actions within the Logic App that will need to be updated every time members of the Action group change so having a single location to change the group members is the preferred method.

Hello Andy Haggith,

Before Azure Communication Service action, we suggested to use HTTP (GET) action to fetch phone numbers details from action group dynamically and pass that in Azure Communication Service action.

{GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Insights/actionGroups/{actionGroupName}?api-version=2021-09-01

}

Note: You can pass action group name dynamically as you required.
