Power Automate – New IP Address Ranges for Power Automate flows using HTTP Actions

Beginning May 1, 2025, Power Automate flows will be leveraging additional service pools to execute flows. This change will impact flows with HTTP actions that connect to resources within your network, if you are restricting inbound traffic into endpoints using firewall rules. What action do I need to take? We have detected you are using flows which utilize HTTP actions. To identify flows with HTTP action(s), you can use the available PowerShell cmdlet. Please update your network firewall configuration to permit traffic from ALL the service tags listed below: LogicApps PowerPlatformPlex If you are not restricting inbound traffic using firewall rules to endpoints that HTTP actions are calling into, no action is required. More information on Service Tags and how to retrieve associated IP address ranges via API or by downloading the information. Why is this action needed? Power Automate needs to update and expand its services infrastructure to maintain its service levels with anticipated usage growth. While we try very hard to ensure services infrastructure updates are transparent to our customers, in this scenario it was not possible to do so. Failing to update the firewall configuration can cause Power Automate flows using HTTP actions to fail if you are restricting inbound traffic disrupting your business processes that depend on the flows.
