Hi,
My open cart website using the "PayPal Checkout Integration" module, has started charging customers twice within seconds. nothing has changed my side. Its not all transactions but I cannot find a pattern, at a guess i would say its mostly when a credit card is used at check out. Is there anyway I can block duplicate payments? About the same time I also started getting auto replys from paypal saying the email address i used to contact them is no longer in use. It has a subject line "Automatic reply to PayPal email SAXK" , maybe this is related somehow? I have no idea where to start looking. Any help would be gratefully accepted

Good day @compusurfjulie,
Thank you for posting to the PayPal community.
PayPal system is a payment gateway, which will receive the payment request payload (i.e. Payment and Item details, Shipping details, Invoice number, Amount details, etc.) from merchant websites(built via third-party platforms eCommerce ) and process the payments accordingly.
Merchants should handle their internal website code and pass the appropriate payment API calls to the PayPal system.
Regarding duplicate orders, I would suggest cross-checking your internal website code and making sure you trigger unique API requests per order.
To know more about how to avoid duplicate transactions please refer to the provided link: https://www.paypal.com/us/cshelp/article/how-do-i-avoid-duplicate-transactions-ts1097.
If you are 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,
Vaishnavi
