Trying to trade my domain names but I need to link paypal, and it doesn't work for personal accounts... So in other words you need to have a business to trade ... domain names?! I have a paypal business account, but it's getting restricted nowadays unless I have an ACN and documents to prove it's a business... I'm just a sole trader.
You need a business account because the PayPal API doesn't work for personal accounts, it's not an issue with DP it's just how PayPal works.
Just FYI - personal PayPal accounts are designed for buying stuff, not selling stuff. Which is why they don't give personal accounts access to things that they intend only for sellers. https://www.paypal.com/us/smarthelp/article/does-paypal-offer-different-types-of-accounts-faq2347
