With the release of the 1.4.1 of the SharePoint Framework we now have the ability to easily call a secured Azure Function via a REST call from our SharePoint Framework webparts. You can do this by using the new AadHttpClient. Link to Documentation Below. https://docs.microsoft.com/en-us/sharepoint/dev/spfx/use-aadhttpclient Why a secured function? There is often times when we want to surface sensitive data into our office 365 tennant. Azure functions are great ways to deliver this data.
