the agreement object have execute method method requires token. token available if use paypal account make recurring payment. documentation on paypal's site outdated , not find sample code either. hope can me this.

you don't have execute or activate billing plan when using using credit_card payment method.

just calling $billingagreement->create($apicontext); create , execute billing agreement.

you can login paypal merchant account , go recurring payments , active profiles. sure you'll find profiles code created under section.
