What business documents or verification did PayPal demand when you used them for the Shopify store?
Huh?Hello, you need some basic requirements, Firstly you need to verify your PayPal account and then integrate it with Shopify while integrating you get some of the steps that you need to follow while integration, the steps do very easy to integrate.
To get verified, go to your account to add and confirm your bank account or, if you prefer, add and confirm your debit or credit card.Huh?
That does not answer the question asked at all.
In fact it just causes confusion.
