I have installed a new version of zencart (2.1.0) together with the integrated PayPal payment module. I set it up to Payflow-UK. When making a payment I am getting a response 'invalid amount' error 04.(It is this one described here (link)). I have checked all amounts and they seem to be ok. Standard PayPal (express checkout) works. I would appreciate your advice on that. Thank you.

If you are not using PayPal RESTful, you should consider moving to it.
Thank you. I really appreciate your help. I will give it a go.
I have followed your advice and installed PayPal RESTful module. Unfortunately I cannot get it right. There are 2 major issues + 1 for Braintree + one page checkout (2.5.4 (2024-11-05))
1. My understanding is that the PayPal Express Checkout button should be displayed as it with standard module. The button is not shown with RESTful option.
2. When paying I am getting this error:
The curlPost (v2/checkout/orders/*...*/capture) request was unsuccessful.
{
"errNum": 400,
"errMsg": "An interface error (400) was returned from PayPal.",
"curlErrno": 0,

}

}
2025-02-17 20:37:20: (checkout_process) ==> End captureOrderWe are unable to process your PayPal Checkout payment at this time. Please contact us for assistance.
3. Braintree module with 3 pages checkout in step 2 of 3 when continue button is hit the 'Continue' text is change to 'Card Processing...'. In OPC 'confirm' button doesn't change to 'Card Processing...' and it looks like nothing is happening.
Would you please be so kind and shed light on those isses. Thank you.
Questions about the PayPal RESTful payment module are best asked in its support-thread: https://www.zen-cart.com/showthread....Payment-Module
1. PayPal RESTful does not include a PayPal Express Checkout button.
2. When posting this issue in the support-thread, please enable the module's debug and include the output of that debug information; otherwise, I've got no clue as to what the 'interface error' details are.
3. The Braintree payment module is its own "animal"; you'll need to contact the developer (Numinix) for issue resolution.
