I am new to paypal and a bit of confused about its types of account and their rules and functionalities. A lot of questions came to my mind while going through those accounts and I searched for them but couldn't get a clear answer on these 1.What is the difference between personal business and developer's account? 2.Do we have to have a real bank account for paypal developer's account? 3.If it is so, then does paypal charges even for developer's account ? 4.If not can we get fake credit from paypal itself just for testing purpose? and finally 5.where do a developer finally login to access the REST API which the paypal provides?
