Clickbank ADD TRACKING CODE and hypertracker doubts

Hi!

I'm New to clickbank and I have some doubts about the clickbank add tracking code option working with HyperTracker.

Firstly ADD TRACKING CODE option is only for sellers, or is it also for affiliates?

To work with HyperTracker i have to choose the option tracking pixel?

I appreciate any help you can give me!
thank you very much,

Joseph
