Whitelist Power Automate IP addresses for Azure Web App

#automation #azure #networking #security

Azure Web App today has blocked access from Power Automate flow with:

{
  "statusCode": 403,
  "headers": {
    "Connection": "close",
    "Date": "Mon, 22 Jun 2026 06:28:40 GMT",
    "x-ms-forbidden-ip": "172.201.236.160",
    "Content-Length": "1892",
    "Content-Type": "text/html"
  }
}
Enter fullscreen mode Exit fullscreen mode

The flow sends an HTTP request to a Node.js endpoint to trigger the sync process. The web app has Access Restrictions set in Networking with a rule that allows Service Tag LogicApps to access the app.

By looking up IP 172.201.236.160 on azservicetags.azurewebsites.net/iplookup I see the following:

IP address 172.201.236.160 is in range of the following Service Tags
Service Tag - AzureCloud - 172.201.0.0/16

So I add another rule to allow traffic from Service Tag AzureCloud.

And the flow is back to normal.
