WHMCS get invoice PDF
<p>I'm trying to import from WHMCS to a c# application all my WHMCS invoices using API methods. There is a problem when I try to download PDF Documents. There is no API method to do that and I can't call dl.php page without login.
I can't login as admin with WHMCS API Methods, and neither with client because (obviously) I don't know their password and I have only their MD5 password.</p>

<p>There is any solutions?</p>

<p>Thanks</p>
