Receiving Application ID from PayPal for this Plugin

I need help using paypal with fundraising:

I have my PayPal account and got my API Username, Password and Signature.

Now I have "problems" registering the application to get my application ID.

I went to the PayPal Developer and logged in with my PayPal account. So far, so good.

But now I have to answer a lot questions and have no idea what to choose.

It asks for "Industry and use cases"; "Additional Infos", "Services used by the app", "Adaptive accounts", "3rd party permissions" and a lot more.

All I want is get the money for my fundraisers over paypal.

So which are the "right" answers to get the Application ID from PayPal?

Anybody did this before and can help?

Thanks, Harald
