Hey, @MRSTUDIO09 !
Before we hop into some troubleshooting steps, have you had a chance to review our help doc on how to set up your PayPal account with Shopify? When you first create a Shopify store, a PayPal account is automatically created for you using the same email address that you used when you signed up with Shopify. This help doc will walk you through the process of ensuring that the correct PayPal Business account is connected.
Since you already have a PayPal Business account, then you’ll just need to deactivate PayPal in Shopify, then reactivate it using the email address associated with your Business account. This is done by heading to Settings > Payments and selecting Deactivate within the PayPal section, where you’ll then see a Reactivate once you’ve disconnected your account.
When you reactivate your account, you’ll be prompted to login to PayPal to complete the activation and grant Shopify permissions. It’s worth noting that if you’ve used another PayPal account recently, the email for that account might already be filled in, so you’ll just need to make sure you’re using the email for the account you want to connect to your store.
Because you’re being immediately directed to your PayPal account, it sounds like you’re already logged in. Is this the dashboard associated with your PayPal Business account, or a different PayPal account?
If it’s the incorrect account, then I would recommend opening up your PayPal dashboard in a different browser window and completely logging out before trying to connect within Shopify again. It would also be worth trying the setup steps again using Google Chrome’s Incognito mode (File > New Incognito Window), or a different browser altogether. If all else fails, do you have another device you can try this on? For example, if you’re currently using a computer, you could try again using your mobile device.
Following these steps should do the trick, but please respond here and let me know if you are still having difficulties connecting your PayPal account!
