Apparently does not work with Version 4.
Hangs in the handshake with PayPal step. Have tried multiple times over several weeks. Same result -- hangs in handshake step with PayPal.

PayPal confirms there is a bug, but has no idea when it will be fixed.
Have you tested with with 4.0.1 ??

From PayPal support:
Hello,
At this time no additional updates are available on the known issue. I do apologize about the delay. CSTS0012575 is currently being reviewed to resolve the ongoing issue.

Hi jjsofttech,

The module is enabled by default. Please make sure that you have enabled it instead of disabling it.

I need your urgent assistance to resolve a crucial issue with our payment module leading to double payments. The pattern remains unclear.

Paypal support suggests a missing header in our payment requests is the issue. Without this header (Invoice Number or X-VPS-REQUEST-ID), our system treats multiple payment requests as separate transactions, resulting in double payments.

Please guide us on implementing this header into our payment requests. Your timely assistance in rectifying this issue is much appreciated.

Thank you,

ray2ding 2 years ago

here is the reply from PayPal: After the investigation, we have confirmed the issue is being caused by your software sending two API requests. The reason why the second API request is not being stopped is because the Invoice Number or the X-VPS-REQUEST-ID is not being passed in.
To resolve this issue, please have your software developers add the Invoice Number or the X-VPS-REQUEST-ID.
We have confirmed that your software has sent these requests separately. Since our gateway has no way of confirming these are duplicate transactions without the Invoice Number or the X-VPS-REQUEST-ID, this is why this is happening.

There is a bug, at least for version 4.x, in extension/paypal/catalog/controller/payment/paypal.php

in line 1287 should not be:
$this->model_checkout_order->addOrderHistory

but:
$this->model_checkout_order->addHistory

Hi webprojectsol,

You are correct. There was a bug in the code for OpenCart 4.x. We have fixed it. If you encounter any other issues, please let us know at support@opencart.com.

Below the Download button at the top of this page it says "Documentation Included". Where? I don't see any documentation or instructions of any kind. I've poked around the js, php, and twig files in this extension. It appears all the "heavy lifting" of integrating with Paypal is implemented - initializing the PaypalAPI, creating an order, sending Paypal all necessary info, handling callbacks, etc. All I need is to have this extension render a "Paypal" and "Use Debit/Credit Card" button on my checkout page. I suspect there's probably one simple line of code that I could put in my cart.twig checkout page and everything will just work. But I can't figure out what it is. Can someone please give me a hint as to what I'm doing wrong?

Same issue here with installing the latest version causes a requirement to CONNECT to PAYPAL which results in the same error that others are reporting:

Authentication failed due to invalid authentication credentials or a missing Authorization header.

At this point I no longer have a working payment method. Please help resolve this! Thank you!

Hi Guys.. Any thoughts about adding the functionality that is currently available in the 'express checkout' integration, namely, the ability to capture, partial capture, refund and void the transaction from the order admin page? It is really complicated to have to go to back and forth between the OpenCart admin and PayPal.com for every order.
