PayPal RESTful API Payment Module

Hello. I'm between a bit of a rock and a hard place. I'm still on 1.5.7D (I know), which this module does not support. It also looks like PayPal is no longer accepting signups for Website Payments Pro so I can't use that module. Express works fine for PayPal, but I want to also use PayPal for credit card transactions. Do I have any viable options short of an upgrade? Would the old Payments Standard work? Could I convert the lang file back to the old format and get the new mod to work in 1.5.7? I figured I'd explore these options before looking at something else like Square.
Thanks much.

Unless told to do so, PayPal will try to get folks to open an account by "hiding" the option for credit card use after so many times the card is used on their system without an actual PayPal account.

If you have the right PayPal account, you can use the steps at https://myzencarthost.com/index.php?rp=/knowledgebase/8/PayPal-Express-Optional-Credit-Card-Setting.html to setup PayPal Express to always present the credit card option.

I would still go with some other form of credit card processing simply to have a backup if one is down. You never know when one might go down. Square was inop for several hours not too long ago. Twitter was down for 43 minutes this morning and T-Mobile for 39.

Thank you. Log on its way.
I can see from the log that the card failed the CVV check. The customer probably mis-typed it. Despite having an account, they had checked out as a guest using OPC.
I'm not seeing receipt of that log, nor am I able to reproduce on PayPal's sandbox.

I've just had another one this evening. I'll PM for your e-mail address in case I got it wrong last time.

v1.0.2 of the PayPal RESTful payment module is now available for download: https://www.zen-cart.com/downloads.php?do=file&id=2382

This release contains changes associated with the following GitHub issues:

#13: Full cost breakdown not submitted to PayPal when the order has discounts
#14: Level-3 Data's ships_from_postal_code "doesn't like" intervening blanks
#15: Correct PHP Warning when voiding a transaction.
#16: Show spinner on transition from the webhook to the target page.
#17: "Identify" as a payment module that collects card-data on-site.
#18: Correctly identify 3DS declined transactions; orders were invalidly being created.
#19: Set an error message in the API class when an interface error is detected.
#20: Correct addresses in the "Channel Islands" (and others) being disallowed.
#21: Correct method-/constant-names when a card-declined reason-code isn't recognized.

Many thanks to @BillJ for his help in debugging and correcting those 3DS-related issues!

ZCA Bootstrap Template v3.6.5

The zoom in/out setting of my browser is 100%, but the Discover Card logo isn't in the same row. Is there any setting I can adjust in this module?

You'll need to provide a template-override for the payment-module's .css file. Copy /includes/modules/payment/paypal/PayPalRestful/paypalr.css to /includes/templates/YOUR_TEMPLATE/css/paypalr.css and then edit this section:

.ppr-button-choice label {
    cursor: pointer;
    height: 2.5rem;
    font-weight: bold;
[B]    width: 11rem;[/B]
    display: inline-block;
    text-align: center;
}

to adjust the width. It looks like **15rem **should work.

Thank you!

I copied /includes/modules/payment/paypal/PayPalRestful/paypalr.css to /includes/templates/bootstrap/css/paypalr.css and then changed the width to 15rem or bigger number, but nothing happened.

My bad. Since you're using the Bootstrap template, copy the paypalr_bootstrap.css file and make the changes there.

It works, thank you!

Cindy,

I am finally getting my 2.0 site up to the point to start testing payment modules. I only saw that this is the new Paypal standard early this morning. We have used Paypal Express almost exclusively to this point. I have read through this entire thread and you mentioned a couple of times that you consider this a Beta release. Is that still accurate?

Also I have installed a new clean 2.0.1 as a dev site on my host and most things are working great (I did the database only upgrade). But I am always uncomfortable testing payment modules. My url for this site is formed like mysite.myhost.com NOT mysite.com so I am curious if that will cause any testing issues. I do have SSL working and that site is trusted. Any thoughts?

I still need to install OPC and EP4 but I am getting close and I wanted to plan out my final testing. I plan to install Zelle and Square as well but Paypal must be working first.

Thanks
Chris

No longer beta; make sure you get the updates for v1.0.2 of the payment module. This thread's been pretty quiet for a while.

Paypal RESTful 1.0.2
Zen Cart 1.58a

Today I tried to make a partial refund. When the dialog came up I entered the amount and clicked the blue "Refund" button. When the red "Confirm" button appeared I inadvertently clicked on it twice. When the page refreshed I saw that two separate refunds had been logged so the customer got his refund twice.
Perhaps it would be worth disabling the button(s) once "Confirm" is clicked, or dismissing the dialog. That would also give some feedback that the process has been initiated. Otherwise the only indication is from the browser (for example, Chrome changes the "reload" button to an "X" while loading the page) and it isn't very obvious.

Finally, one minor enhancement would be to place the refund transaction ID on the message stack so it appears at the top of the page like it does on the "old" Paypal module and others. That makes it easier to copy the ID to put in our accounts system when we create a refund, since the ID is right at the top of the page when the page reloads. It isn't a big hassle to scroll down to the messages to find it there, though.

Zen Cart v1.58a
Paypal RESTful v1.0.2
Payment Action: Auth Only

I disable PayPal Express Checkout and enable Paypal RESTful today.

There are two orders. The 1st order is paid by PayPal Wallet, and the 2nd order is paid by Credit Card.

The 1st payment goes through, but the 2nd order gives me an error:

The payment module's observer (auto.paypalrestful.php) was not loaded; the payment module has been disabled. The payment module has been automatically disabled.

Both orders get this error when I capture the payments, but I can get correct $$ into my PayPal account:

Request URI: /ipn_main_handler.php, IP address: 173.0.81.140, Language id 1
--> PHP Warning: Use of undefined constant MODULE_PAYMENT_PAYPAL_ORDER_STATUS_ID - assumed 'MODULE_PAYMENT_PAYPAL_ORDER_STATUS_ID' (this will throw an Error in a future version of PHP) in /zencart/ipn_main_handler.php on line 475.

Something under PayPal Transactions doesn't look right.

[Attachment no longer available]

Should I remove PayPal Express Checkout completely? Or any possible issue I missed?

Why would I be getting an expired token? This is me trying to ENABLE the RESTful module.
