Redirect to payment successful and mark invoice as paid

[eugene@inx.co.za]

Good day

 

I need some help and was wondering if someone could point me in the right direction.

 

I am using a payment gateway called VCS and they have a plugin on there site.

So everything works perfectly to get the payment done but when it tries to redirect back to my site it fails.

 

So what I want to know is the URL that should be redirected back to whmcs for the payment to be marked as paid

and also that the service that the client ordered be activated.

 

And then the reverse if the payment was declined that it redirects back to whmcs to the invoices page.

 

I have contacted the vcs guys and they stated that I will need to manually modify the module to get it to work.

But I am just lacking the url's

 

Here is a link to the module I am trying to use.
