Wrote a blogpost how to send a Tweet from PowerShell, the script I reused and adjusted is here (Original script is from ? and was posted on Techgallery) Please read to post for information in how to create API keys etc. https://powershellisfun.com/2022/08/01/create-a-tweet-on-twitter-using-powershell/
function Send-Tweet {
param (
[Parameter(Mandatory = $true, HelpMessage = "Enter the message in 140 characters or less")][string]$Message

Write-Warning ("Length of tweet is {0} characters, maximum amount is 140. Aborting..." -f $Message.Length)
