Rest API call works with curl but doesn't work with PowerShell - powershell

Question

I have following curl request that works
curl.exe -X GET "https://host.crm.dynamics.com/api/data/v9.1/accounts?$select=name" -H "Authorization: Bearer xxxxx"
And want to implement it in PowerShell
Invoke-RestMethod "https://host.crm.dynamics.com/api/data/v9.1/accounts?`$select=name" `
-Headers #{Authorization = "Bearer xxxxx"} `
-Method Get
I've also tried to do request with Invoke-WebRequest as well as curl version in Powershell and it didn't work
Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send.
At E:\Repos\myrepo\host\connection_test.ps1:51 char:1

Answer 1

When making connection using Invoke-RestMethod, you want to make sure that encryption your client is using is accepted by the URI.
PowerShell by default uses TLS 1.0 for web requests but the URI you are connecting to probably uses 1.1 or 1.2. You can use the following to force the use of TLS v1.1 or v1.2.
[Net.ServicePointManager]::SecurityProtocol = `
[Net.SecurityProtocolType]::Tls11, [Net.SecurityProtocolType]::Tls12;
Invoke-RestMethod "https://host.crm.dynamics.com/api/data/v9.1/accounts?`$select=name" `
-Headers #{Authorization = "Bearer xxxxx"} `
-Method Get
