Hi traxport121,
My name is Marco and I'm with Payza's Online Community Team.
After having contacted our Integration department concerning your question, they have explained to me that you will have to contact WHMCS to have the URLs changed to Payza.
We also suggest you have a look at our transition guide

Kind regards,
Marco
