I don't a log in after installing through API

[noandnoandnoandno]

I am unable to install the PayPal option in payments because when I installed PrestaShop I did so through the API and I guess that means I don't have an account on here? I created this one because I HAD to after realizing it would not take my email due to have 3 "s" in the email(?!).  So I have this log in but it's not associated with my shop at all. 

I am using a PrestaShop intall through API connected to Printify. How can I make it so that the prestashop account is connected to my shop?

I want to be able to take PayPal and other payments in the future.
