Integration with Shopify: This email is already being used for a PayPal Business account!

Posted on



I try to activate PayPal on my Shopify account.

But paypal show me: "This email is already being used for a PayPal Business account. Log in, or use a different email address to sign up."

and then: 

Automatic payments Denied

PayPal denied our request to accept automatic payments. Customers can’t use PayPal Express Checkout to pay for subscriptions, deferred purchase options, or post-purchase offers.
I have tried a lot of ways, but have not found a solution, can anyone help me, thanks



Integration with Shopify: This email is already being used for a PayPal Business account!

Good day @suisser,


Thank you for posting to the PayPal community.


This should be an issue with your third party API permissions setup with the “Shopify” Partner. 


I would suggest to please contact your third party platform(Shopify) who can able to help you onboard/link your LIVE account.


Here are instruction on how to manually the merchant can view any partner consent they have given:
1. Log into your PayPal account
2. Hover over your account name in the upper-right corner
3. Click "Account Settings"
4. On the left under "Products and Settings", click "Website Payments"
5. Click "Update" next to "API Access"
6. Under "Pre-built Payment Solution", click "Manage API Permission"
7. Click the checkbox next to SignUp
8. Click "Yes, revoke"
9. Reattempt to integrate onboard.


Merchants can manually grant permission to a third party software to access specific information in your PayPal account and perform PayPal API operations on your behalf.
Login >> Settings >> Account Settings >> Website payments >> API Access >> Pre-built payment solution >> Grant API permission >> contact your "Third party software (Shopify)" for Third Party Permission Username >> enter the username.

If your still facing any issues, please create a MTS ticket via - with the detail information and error details.
