Call Azure Function from Powershell

I was fooling around with Azure Functions and wanted to try calling a Webhook function from Powershell. I just wanted to test a simple function from Powershell

I kept getting an error saying that 'The underlying connection was closed: An unexpected error occurred on a send' when I used Invoke-RestMethod.

Turns out that for some reason, you have to force Powershell  on TLS 1.2

When I ran this command to do that -

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

it worked and I got my 200 OK response.

To reset, you can run this command -

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls

Hope this helps anyone out there struggling.
