As a first step, go to the Azure portal to create a function app that will host the execution of the Azure functions used by PoolParty for SharePoint. You need a dedicated function app for each module (the Tagging module, the Term Store Synchronization module) of the PoolParty for SharePoint application.
Note
Alternatively, you can create a function app with a custom PowerShell script.
Expand the portal menu.
Select Function app.
Select Create.
The Create Function App page opens with the Basics tab activated by default.
Select .Net as a Runtime stack and 6 as a Version.
Use the other options on the Create Function App page to configure the function app according to your needs.
Confirm with Review + create.
Note
You need a dedicated function app for each PoolParty for SharePoint module (the Tagging module, the Term Store Synchronization module) you want to install.
