function Get-PasswordStatePassword {
    <#
        .SYNOPSIS
            Get a password object from PasswordState.
        .DESCRIPTION
            Get a password object from PasswordState.
        .PARAMETER ApiKey
            The API key for the Password list
        .PARAMETER PasswordId
            The Id of the password in PasswordState.
        .PARAMETER Endpoint
            The Uri of your PasswordState site. (i.e. https://passwordstate.local)
        .PARAMETER Format
            The response format from PasswordState. Choose either json or xml.
        .PARAMETER UseV6Api
            PasswordState versions prior to v7 did not support passing the API key in a HTTP header
            but instead expected the API key to be passed as a query parameter. This switch is used for
            backwards compatibility with older PasswordState versions.
        .EXAMPLE
            $password = Get-PasswordStatePassword -ApiKey $key -PasswordId 1234 -Endpoint 'https://passwordstate.local'
        .EXAMPLE
            $password = Get-PasswordStatePassword -ApiKey $key -PasswordId $id -Endpoint 'https://passwordstate.local' -format json
