Fundraiser payment settings

Hello, I'm configuring the Advanced Crowdfunding settings within the Fundraiser Plugin, however all documentation you've published on the setup is outdated.
What 'app' do I have to request from PayPal? REST API app or NVP/SOAP API app, and where is the form to do so?
Also, because it's directly linked to PayPal's Adaptive products, will this update from PayPal disrupt the entire plugin?
