Cancelling invoice by API doesn't trigger hook

[steph.hope]

It seems that setting an invoice's status to cancelled via the UpdateInvoice API doesn't trigger the InvoiceCancelled hook. This is a problem as it seems that a 3rd party module we're using makes use of that hook to identify cancellations. Is there any other way to cancel an invoice by API that would work better?

I believe the updateinvoice is the only api that does that.  You can try doing this via internal classes on the Invoice class https://classdocs.whmcs.com/7.8/WHMCS/Billing/Invoice.html

Something like:

<?php

$Invoice = \WHMCS\Billing\Invoice::find($InvoiceID);
if ($Invoice)
{
   $Invoice->status = 'Cancelled';
   $Invoice->save();
}

Have not tested if the hook will fire with that though.

or for v8 - https://classdocs.whmcs.com/8.0/WHMCS/Billing/Invoice.html

Ah had not seen 8.0 docs yet.  In there there is a setStatusCancelled() function that would likely be better.

It doesn't seem to 😞  And unfortunately we haven't upgraded to v8 yet for a host of reasons. That's fine, we'll work around it somehow.
