I have a scheduled flow inside power automate and our tenant is in the US and the power automate enviroment is in this region:-

now the power automate flow calls external api (not within Azure) using the Send Http Request Premium connector, and we want to secure the external api by adding ip ranges to the white list , so how i can know my power automate ip or ip range to add it to the white list inside the api?

Hi @johnjohnPter

The Microsoft documentation on this wants you to use Service Tags rather than IP address ranges, which can change over time. If you need a raw list of IP addresses, you can use the links found here.

Using the last link from my first post, there are links to download a JSON of each region's IP range. The reason this is a link reference is because when the IP ranges shift, that JSON file will always have the most updated list of addresses.

The first two links are documentation for how to use Service Tags, which would automatically get the newest IP range list automatically instead of manually updating the ranges every so often.

I count 605 IP ranges for the tag AzureConnectors (the tag for outbound calls) for the US region

This link from my first comment then from there click the link for the region you want. That will bring you to the download page for the JSON file. Then scroll down to the AzureConnectors tag and look for the addressPrefixes array.

Note that this file was most recently updates October 20th. These address ranges change regularly, so you should really use the Service Tags option to dynamically gather the lists.
