When fetching data from data sources that require IP whitelisting for requests from Power Automate or Logic Apps, Microsoft provides a nice list of IP addresses that should be whitelisted per region. This is nice, but it does not actually work. Quite often, the IP address of the flow is something else than mentioned online.
Luckily, I found this link: https://www.powernimbus.com/2021/04/whats-the-ip-of-my-flow/
There’s a great way to see what the IP address is by using a 3rd party API:
GET request to https://api.ipify.org/?format=json
Here’s a link from where you can find the IP address that is not mentioned in the website documentation: https://www.microsoft.com/en-us/download/details.aspx?id=56519&WT.mc_id=BA-MVP-5003527
However, I’m still struggling to understand which IP Addresses should be whitelisted, as I wouldn’t like to whitelist all of them.
