I read the documentation from PayPal and there is one section stated that
"You can use the following standard services without requesting specific permission:
Making simple or parallel payments that require explicit approval of the sender
Getting payment details
Making refunds
Performing currency conversions
To use any other service, you must receive permission from PayPal to use the service when you submit your application."
Does it mean that if I want to use Adaptive Chained Payment I need to ask for special permission from PayPal ? if so how would I submit the request ? Is there any possible obstacle ?
