Hello , I have a problem with the Paypal Express button. When the customer tries to pay via express checkout, the first payment attempt doesn't work and I get an error message that they should try later. I am really desperate what to do

Good day @Nasrat03,

Thank you for your post and welcome to the Community Forum.

I would suggest to please try contacting your website developer or the support of Shopify to cross check the plugin/module issue. 

Steps to integrate PayPal Express Checkout with Shopify. 

1. Log in to your Shopify admin panel.
2. Click Settings.
3. Click Payments.
4. Select PayPal Express Checkout within the PayPal module.
5. Click Activate.
6. Once directed to a PayPal login page, log in to your PayPal account and click I Give Permission.
7. Click Back to Shopify.
8. Under Payment Authorization, select:
   • Automatically capture payments for orders (Immediate Sale).
   • Manually capture payment for orders (Authorize only).
9. Click Save.

This does not resolve it.  If I am honest, I think this is a serious problem infiltrating Shopify and Paypal that neither want to take the blame.  We have had issues with paypal for over a year.  Being trying to solve it for a year.  No one can help.  

If you want crazy theories.  I think shopify is doing it on purpose as they want people to use their Shop Pay system.

Good day @hgqwerioghwoie,

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 obtain 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/.

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

Sincerely,
