How to register MarketPress application

Hi, when setting up MarketPress on a Multisite network, I would like to configure PayPal Chained Payements. My API credentials are obtained and filled in but how do I get an Application ID? The link "Register then submit your application" is dead.

Searching the Paypal Development Center, I reached https://apps.paypal.com/user/my-account/applications/new which looks like the correct alternative. Can anyone confirm that?
