Not able to integrate PayPal with Shopify

Shopify Discussion

Topic summary

PayPal Express Checkout activation on Shopify is looping to “Complete your setup” in PayPal or failing to finalize authorization for multiple merchants, even when PayPal accounts appear fully set up. Some also report an ERR_TOO_MANY_REDIRECTS error or PayPal payments stuck as “pending” with a review message and no follow-up notifications.

Shopify support notes Shopify auto-assigns the store’s signup email to PayPal and that after the first PayPal sale, PayPal emails a link to complete setup. Suggested basics: deactivate/reactivate PayPal in Settings > Payments, clear cache, try a different browser, and use desktop instead of mobile.

Several community fixes show success:

  • In PayPal: remove Shopify under Settings > Account settings > Service providers (or Settings Tools > API Access > Manage third‑party access), then reconnect from Shopify.
  • When redirected to PayPal, log in and grant permissions, then click “Back to Shopify” (do not click “Complete setup”).
  • As a reset, temporarily activate PayPal Payflow Pro (with dummy details), disable Express Checkout, then deactivate and re‑activate Express Checkout after a short wait.
  • Regional quirk: testing from India (when the store doesn’t sell to India) blocked activation; testing from Belgium worked.

Status: Mixed results—many resolved via permission removal/return to Shopify; others remain unresolved (redirect errors, review loop, email mismatch). Screenshots show the PayPal authorization page and errors but aren’t required to follow the fixes. The discussion remains open.

Hi,

I have a similar issue.

I am unable to activate the Paypal account. In my shopify store there is no DEACTIVATE button when I go to Settings > Payment providers.

There is only a ‘Activate PayPal Express Checkout’ button and when it is clicked on it takes to the Paypal account. I also tried using a different browser. My Paypal account is fully set up and the email id for the logic is also the same. My Paypal account is a business account and i have received confirmation from Paypal that i can receive money in the account in both INR and USD.

Please guide.
