Purchase with paypal credit

I purchased a new Mac machine using Paypal Credit and spreading the cost on 24 months.

My question is if i need to do anything else? I have checked my Paypal Credit account and it came out of my credit balance but it doesn't says nothing about direct debit set up and says also no payments due.

Is it done all automatic so I dont have to set up a direct debit on Paypal Credit?

Many thanks for your answers
