preauth and capture

[Summy]

At the moment we use WorldPay for collecting payments. We do this in "preauth" mode. i.e. a shadow is placed on the card when they sign up, we then run fraud checks etc, if all is ok we provision the account. Worldpay is set to automatically capture the funds 2 days later. If it was a fraud sign up, we don't provision the account, and log into the Worldpay admin and abort the capture of funds.

 

We are now looking at moving to ProTX when we fully impletement WHMCS.

 

There doesn't seem to be any "preauth" option for the ProTX module, so my question is, how does the ProTX module work in this respect? Does it simply capture the funds straight away when the customer signs up?

 

I read here from Matt that it preauth's then captures: http://forum.whmcs.com/showpost.php?p=23600&postcount=10

 

How does that work, does it preauth when they sign up, and then when/if you provision the account does it capture the funds?

 

Could someone please clarify?

 

Many thanks

The preauth and capture is done all in a single request. ProtX call it the payment transaction type. As in the post you reference, you could have a custom modification done to have it do a pre-auth only and then capture payments later from the ProtX vendor panel.

Thanks Matt, I've updated the ticket asking for pricing etc on the custom mod.
