I 'd like to know if it's possible to use my paypal sand

Hi
I 'd like to know if it's possible to use my paypal sand box account that i've created for appointment plugin.

I mean, i would like to test affiliates plugin, and i would like to test it in sandbox mode. So can i enter in Affiliate Referals tab when it says "PayPal Email Address" the email that i use with appointment plugin in "sandbox mode".

Thanks
