PayPal RESTful API Payment Module

Yea, I need to come up with a better GUID; that's where the 'already captured' message is coming from.

could you just use php function uniqid?

Think if would also be nice if an email was sent to the administrator if the status is changed because of an error.

It's a matter of choosing variables that are part of the uniquid; I'm already using a sha256 hash to create that GUID.

I'm unclear as to what condition an email should be sent to the admin as the processing already sends an email to the admin if the configuration is auto-disabled.

I am testing this module against a sandbox account and have come across a problem.
If a customer makes a sucessful purchase using paypal restful and then attempts to make a second purchase with out loging out one of 2 things happen.
The first time I tried it the paypal restful module was disable so paypal could not be used for the second transaction.
This produced an admin log. (so it may have been a different issue as i sucessfully issues a refund).

The second time I tested it (having logged out and back in) I got the message " We are unable to process your PayPal Checkout payment at this time. Please contact us for assistance."
I think this is the pertenat bit of the log file

    "errMsg": "An interface error (422) was returned from PayPal.",
    "curlErrno": 0,
    "name": "UNPROCESSABLE_ENTITY",

        }

This is against zen cart 2.0.1 using php 8.3.9 mysql 8.3.9
If you need any further info please let me know.

Zen Cart v2.0.1
paypalr-1.0.2
https://alchemycabinet.com

I'm trying to get this plugin to work. I used to use it or one very similar with great results, so I'd really like to get it up and running again.
I may not have my configuration data correct on the PayPal side; I may have to contact them to help me with that.
Before I do that I want to make sure the Zen Cart side is functioning properly, but if I do a test run to check out with PayPal, I get the following errors:

The cart sends me to this url: https://alchemycabinet.com/ipn_main_handler.php?type=ec which simply says the cart can't handle the request.

The admin logs send me these errors (both errors for each instance):

I have no idea what is going on there as I don't have any coupons enabled or in use.

Thanks in advance for any help you can give. :)

ETA: I don't have either of the other PayPal modules enabled, so I don't think they're interfering with each other.

The logs "say" that you've got PayPal Express Checkout enabled and that's what was used to pay for the order.

Okay; so why was I taken to a page that says the cart can't handle the request? Is that on the PayPal end?

[mikecnz]

ZC 2.0.1 on local host.
Have installed Restful API and got my credentials (Client ID/Client Secret) from Paypal, but the mod wont activate.
I get this message:
The live credentials for the paypalr payment module are invalid. The payment module has been automatically disabled.

Do I have to test from a live site?

Because that resulted in a PHP Fatal Error, i.e. a Server 500 error.

I've successfully used live credentials on a localhost test environment.

Try turning on the module's debug configuration setting. That will create a trace-log in the site's /logs directory that might have additional information.
