Use ShoutOut, GAds, BingAds, etc... if you want pay for buyers :D
Click Seller Preferences on the left side of PP Account
And then click Update aside API Access
And then there should be data you need :)
P.S. You don't need upgrade to business
you should go to Appearance>Menus and there you can arrange Menus and Submenus like on the photo
As for prices you should turn-off Rounding in AliDropShip>Settings>Prices
That should be it :)
