Paypal Express Checkout Not Working

[Yecats777]

Hello, we have had a Shopify website for many years and have never had issues with the express checkout until recently. For 2 months now there has been an issue when customers try to checkout clicking the PayPal option in the express checkout menu. They have reported that it takes them through the checkout process and at the end when they click to complete it doesn't actually send it through but sends them out of the paypal checkout process as if it has been completed. Now customers are also reporting time out screens, the page freezing, pending charges put on their account when no order has been sent through to us, and endless loops where they are kicked out of the PayPal screen. These issues only occur with the express checkout button

Good day @Yecats777 

Thank you for posting to the PayPal community.

I kindly request that you retry the process by following the below guide links:

To process PayPal Express Checkout payments, please contact your website developer or the support of third party platform(eCommerce) to handle their internal website code and initiate the payment by triggering the SetExpressCheckout API call from your website to the PayPal system via -  https://developer.paypal.com/docs/archive/express-checkout/ec-initiate-payment.

Once the payment has been initiated, the merchant's website can trigger the GetExpressCheckoutDetails API call to retrieve buyer/customer information, such as name, email address and delivery address, from PayPal.

https://developer.paypal.com/docs/archive/express-checkout/ec-get-payment-details/

Finally, the merchant's website must trigger a call to the DoExpressCheckout payment API to recover the buyer/customer's funds via -  https://developer.paypal.com/docs/archive/express-checkout/ec-finalize-payment/.

Third party platforms eCommerce develops their own plugins/modules. 

Also, I would suggest to please contact the support of your third party platform(eCommerce) who can able to help you regarding eCommerce plugins/modules setup and follow the above steps.

If your still facing issues, please create an MTS ticket via - https://www.paypal-support.com/s/?language=en_US  with the detailed information and error details.

Sincerely,

Kavya
