# The function URL appends the function name with a question mark and a code. This code is the function key and
# authenticates to the function for execution. Without this key, you would not be able to trigger the function.
# This key provides security so not just anyone can start the function.
$functionKey = '' ## Fill this in from the Get function URL page
$functionAppName = 'ata-powershell-functions'
$loggerUrl = "https://$functionAppName.azurewebsites.net/api/LoggerFunction?code=$functionKey"

# Next, build the HTTP request body object using a PowerShell hash table. The HTTP request body contains two pieces
# of information to pass to the function: the severity of the log entry and the log message.
$requestBody = @{
    Severity = 'INFO'
    Message = 'This is my first Azure Function using an HTTP trigger.'
}

# Convert the PowerShell hash table into JSON using the ConvertTo-Json command and storing this to a new variable.
$requestBodyJson = ConvertTo-Json -InputObject $requestBody

# Finally, invoke an HTTP request. Use the POST method and specify the body and URL already saved to variables.
