On the extensions page, payments, there is a down arrow to download "PayPal Checkout Integration"

I have logged off and back on, and each time I try it from this page it says "Signature hash does not match!" (in Red)

Appears I need to enter an API key somewhere.

So I went to System/User/API, and I have an API key #.

Where do I add this?

-----------------------------------------------alternate way tried----------------------------------------------

So I tried downloading version 4+ of this extension from "PayPal Checkout Integration" on opencart.com extensions page.

OCMOD version, I went to INSTALLER, UPLOADED it, it then lists it on the list of installed extensions.

But it is partially grayed out at the bottom of this list.

I clicked the EDIT button and it just pops up a box with no way of addressing anything.

On the MODIFICATION PAGE: I tried CLEARING and REFRESHING to no avail.


What am I missing? THANK YOU

I would suggest avoid using OC 4 at this time, unless you want to hire someone to take a look and keep fixing the bugs for you. if you do feel free to drop me email for free estimate.

Or you could try the latest V3.2.4 of the PayPal Integration from dreamvention.
However, as khnaz35 has pointed out, OpenCart 4.1.0.3 has a number of known bugs, for a stable version we recommend OC 3.0.4.1.

PayPal Integration from dreamvention.
To be candid, their response time in addressing bugs and releasing extension patches has been remarkably slow. Despite having submitted a working fix myself—and noticing that Michall has done the same—the issue persists. At this point, one can only assume they're either exceptionally busy or have entered a witness protection program for developers.
