How does Spigot use paid resources in Xenforo RM

I wanted to know how to make paid resources/plugins in the Xenforo RM. I know this is possible with the External URL option, however I want to host and process files locally. I see that spigot uses some form of PayGates, however I am unsure as to how a user can specify his/her own PayPal account instead of using the one in User Upgrades.

Thanks for the help.

 

Any responses? I would really appreciate any help.

 

I have the resource manager and paygate, I just can't figure out how to have a user specify his/her own PayPal address.

 

Oh. Did you use PayGates and customize that?
