PayPal RESTful API Payment Module

chadlly2003:

PayLater Messaging- On the Shopping Cart page, the PayLater messaging should display an offer based on the total value of the items currently in the cart when the PayPal message is clicked.....

Just like the Paypal Messaging for the Product Page. Thats works just fine

This weekend I am going to dig into this paypal issue I am having. Not really sure why i am having these issue
I think its could be a browser setting or Server issue - too be continued

It seems to work for me. I went to an item we sell for $99.00. On the product page, it displays: "Pay in 4 interest-free payments of $24.75"

I added it to my cart and on my Shopping Cart page, I see the same message: "Pay in 4 interest-free payments of $24.75."

I'm on Firefox and running the latest version of the module (1.3.1), although I am still on ZenCart 1.5.8a.

To get it to work for my bootstrap template i had to edit
includes\classes\observers\auto.paypalrestful.php

find:

'container' => '#shoppingCartDefault-cartTableDisplay',

replace with

'container' => '#shoppingCartDefault',

May have been my template

Rather than altering the 'core' module file, you could either upgrade the PayPal/Restful module to v1.3.1 or update your copy to include these (https://github.com/lat9/paypalr/commit/39c8b2fe333981ed321cabbf73fabfae43c44e06) changes. That adds a notification through which you can modify the $messagableObjects array via an observer.

I'm not sure what modifications you've made to your version of the Bootstrap template, but that previous 'container' value works just fine for the as-shipped version of the template.

I am using version 1.3.1. It must be my template

also getting this error forgot to post it

Content-Security-Policy: The page’s settings blocked a JavaScript eval (script-src) from being executed because it violates the following directive: “script-src 'nonce-xxxxxxxxxxxxxxx' 'self' https://.paypal.com https://.paypalobjects.com https://*.googleapis.com” (Missing 'unsafe-eval')

That's PayPal's CSP, and affects PayPal's loading of PayPal objects, from PayPal servers (where the CSP is) into the elements that PayPal creates on your page. Nothing you can do about it. I reported it to them months ago.

DrByte,

You are 100% correct. This is what I also found to solve
issue. But not really a solution. This is a know issue based on the research i have done

When using the default “Remember history” setting in Firefox, the PayPal guest checkout with a credit card sometimes gets stuck in a redirect/loop during the checkout process. However, if I change the setting under Privacy & Security from “Remember history” to “Never remember history,” the guest checkout works normally without any looping.

Based on my testing, switching to “Never remember history” seems to make Firefox behave similarly to private browsing by limiting stored session data, cookies, and history. This appears to prevent whatever session or cookie conflict is causing the checkout loop.

This behavior seems specific to Firefox, as I have not experienced the same issue in other browsers.

My main concern is whether a customer using the default Firefox settings might encounter the same issue when attempting to complete a transaction.

**Note I already have some customer complain about this.

Noticed that the PayPal Pay later messages that show on the shopping cart page, showing the 3 payments that could be made only work on the total of the actual shopping cart.

The shopping cart totals in our case, are exc vat prices, and there is UK VAT to be added, as well as shipping costs on orders that are below a certain value.

When a customer completes a purchase normally, and goes through to the final page, the VAT and shipping costs are then shown, but not sure how this would work if a customer choose the PayPal pay later option???

My question is, if a customer completes a purchase this way will they get charged the total price including VAT and shipping costs; or will this only work on the shopping basket total value?

Kind Regards,

Andy

When a customer completes a purchase with PayPal Pay Later, they get charged to total order price (which isn't available on the shopping-cart page).

Thanks for confirming lat9.

Kind Regards,

Andy

This support-thread is now shared by the encapsulated (https://www.zen-cart.com/downloads.php?do=file&id=2434) and non-encapsulated (https://www.zen-cart.com/downloads.php?do=file&id=2382) versions of the payment-module.

When posting a question (or issue), please be sure to include the version of the payment-module you're using.

Testing zencart 2.2.1
php 8.4
**Note I am testing this on a local machine using xampp

I enabled the PayPal Checkout (RESTful) plugin that comes with Zen Cart 2.2.1.

However, when I try to activate it, I receive the following error:

“The live/sandbox credentials for the PayPal payment module are invalid. The payment module has been automatically disabled.”

I recently completed an upgrade, and know the credentials I entered are correct.

Any ideas what would cause this?

Other than the credentials being incorrect, I don't have ideas. You could turn on the module's Debug setting and retry; that'll have the PayPal transaction and PayPal's response.

It strange because the exact same setting work on zencart 2.1 with php 8.2. When I do the upgrade to zencart 2.2 and php 8.4 is when the problem occurs. The module does not work when i use the encapsulated or non encapsulated.

I also tried it on a clean install with the same results.

I also enabled debug mode in paypal; module. Not populating a log unless I am looking in the wrong section. /logs/

I figured it out — the issue was on my local XAMPP setup. There was no SSL/CA bundle configured, so PayPal couldn’t validate the connection. Once I added the SSL certificates, everything verified correctly.

It looks like now, even in a testing environment, SSL is required for authentication with PayPal.

Where did you do that. I installed Zen Cart 2.2.2 and cannot find it nowhere.

https://github.com/zencart/zencart/tree/master/includes/modules/payment

paypal.php = standard
paypaldp.php = website payments pro
paypalwpp.php = express checkout

If I dive into the documentation there should be something like paypalr.php ?

edit: Oh I eventually found it @ /zc_plugins

zc 2.1.0. paypalr 1.3.1

I just installed paypalr for the first time. I enabled the credit card payment. Under the checkout page, it looks like "Paypal wallet" button is selected by default, so the credit card number box is not displayed. Is there anyway I can change the default option to "credit card" instead?

Also, under the shopping cart page, there is no paypal express checkout button anymore (like paypalwpp). So everyone needs to click on "Go to checkout", right?

Do you have payment modules other than paypalr installed?

Yes, there is no "express checkout" button for this payment module; everyone runs through the checkout processing.

lat9:

Only paypalr and check/money order are enabled for this testing. paypalr is selected by default. Under paypalr section, there are two options: PayPal wallet and credit card. Paypal wallet option is selected by default. I'm able to edit jquery.paypalr.checkout.js file so credit card option will be selected by default instead.

I see. So now, if a customer wants to pay the order by paypal instead of a credit card, he needs to enter his address over the websites. On one end, with paypal express module, the customer can choose the saved one from his paypal account, which might be more convenient. On the other end, also paypal express, sometimes paypal saved address will overwrite the address entered on the websites, which also cause some issues.

The customer doesn't have to enter their credit-card on the paypalr form; they can use the "Wallet" and (after signing into their account) then select the card to be used.

I'll consider adding a configuration setting to determine which PayPal payment method (wallet vs. card) is initially selected.
