Than I also have:

I am confused it looks like it's getting IPN but getting message in store when I click return to merchant is this maybe the problem?

Also nothing in balance

Similar here...and order in "pending" - never registers that payment was successful etc.  (Sandbox mode at moment)

 

Also trying to view order fails...invalid transaction ID or something along those lines.

Suddenly I can't edit a post anymore....weird.

Further to the above message - I am using the Points and Rewards.  I cannot test a live transaction since Paypal decided to put my personal account through a security review because I was trying to order Christmas items on ebay - and there were 3 different currencies so they flagged me.  On a side note, they gave me a $10 "credit" to use - although it'll expire before they allow any transactions.

That aside....I did confirm with them my Business Account and Sandbox accounts are not affected by this.

I will post my checkout_process.php to this as well in case that is the issue.

Here's what happens:

1. add items to cart

2. checkout (paypal sandbox)

3. Paypal reports success

4. Paypal APP log shows transaction and IPN received (I DO NOT use nor have I setup IPN in either the sandbox or live paypal accounts)
--> PDT is configured and the return URL is set.  This appears to work properly and at least returns properly.

5. Status shows Paypal [Transaction] in orders - it is never confirmed.

6. Order confirmation email IS sent out.  Order in admin should show completion and does not (Admin->Orders->Orders)

7. Attempting to view transaction history in Paypal sandbox account: no activity

I am beyond confused and lost.

checkout_process.php

@tornrawks there's a time limit on editing a post - after a while you can't.

Order status Pending is what you normally get on an order that has been paid.

By default, they get created in a Preparing state, and changed to Pending on receipt of payment.

Paypal [Transactions] is a logging order history that shows you the IPN has worked.

Does the customer end up back at the beginning of the checkout process with the message that's the subject of the thread: "Could not verify the PayPal transaction. Please try again."?

If so, that is your actual issue. The return from pp is failing and not going to checkout_success.php

I have just hit the same thing setting up pp standard in sandbox mode for a client and will let you know what was causing it for them when I have sorted it out. It's likely a configuration thing.

@tornrawks in my client's case they were using a sandbox merchant account that had an unconfirmed email address - I think it had been created via the 'fetch Sandbox credentials' dialogue from osc. The symptoms (customer being returned to the shopping cart with the error message) were the same. If you look at the Paypal log in admin, you'll see that there's a successful _notify-validate [IPN] and a failed _notify-synch

On the way to a solution, different details to the error logging were thrown up with different aspects to the resolution

  • without PDT set up at all, there was no response to the _notify-synch
  • with apparently all the proper settings in the sandbox merchant account and the matching token in osc, but with an unconfirmed email address in the merchant account, error response 4010. Sandbox accounts don't send actual emails and I was unable to find a way of confirming it since it was not associated with a developer account. If you sign in to developer.paypal.com and create a sandbox account there it doesn't need confirming.
  • through carelessness in going from one setup to the other I also made it throw a 4011 error when the PDT token in osc was different to the one in the paypal account

Suggested approach to configuring paypal sandbox account for testing:

  1. Log in to developer.paypal.com and create two accounts to use: a business account (to represent your shop) and a personal account (to use for placing test orders)
  2. Log into sandbox.paypal.com with your new business account. Go into the settings / My selling preferences / Website preferences / set Return to my website On, return url to http://domain.com/checkout_process.php, Payment Data Transfer to On, Encrypted payments off
  3. after saving these settings, go back in to get the PDT token
  4. fetch the sandbox credentials into osc using the new business account
  5. paste the PDT token into the configuration

NB when you go live you will need to replace the sandbox PDT token with one taken from the live paypal account

I'm FAR from an expert, but I found a solution to this. It's not a real solution, but it seems to work for me. The transaction seems to work, it just doesn't redirect back to oscommerce successfully, oscommerce thinks there's an error when the transaction was successful. So, what I did was commented out some lines (I have OSCommerce 2.3.4 and paypal app 5.0.18) in ssl\catalog\modules\payment\paypal_standard.php:

Around lines 635 or so:

Quote

 

      if ( $result != 'VERIFIED' ) {
        $messageStack->add_session('header', $this->_app->getDef('module_ps_error_invalid_transaction'));

        tep_redirect(tep_href_link(FILENAME_SHOPPING_CART));
      }

 

Hope this helps someone else. Even though the result is not verified, everything seems to work. My order history shows "pending", and the user sees success, and the order shows up in history, and cart gets cleared.

@thwang the point of this code is to validate that your customer has really paid for the item at paypal. If you comment it out, it leaves you open to being tricked.

Whilst it's more popular for hackers to try to hijack your paypal module and send your customers' payments to a different account, I have seen instances of faked payments trying to get you to send out orders that are not really paid for.

What you should do is sort out your settings so that the delivered code works properly. Unless of course you don't mind giving stuff out for free.

I had PayPal App v5.010 configured and working perfectly.  Then, like an idiot, I upgraded to v5.018.  Now it's broken as others have experienced.

Ran multiple tests in Sandbox and now I'm also getting the dreaded "Could not verify the PayPal transaction. Please try again."  It does not return to the correct checkout_process.php page, but goes back to the Shopping Cart and it shows the items still in it. 

The Sandbox account shows the payment coming through, but the osCom status updates look different.

Now I also don't get: (1) the order confirmation email or (2) the PayPal payment confirmation email. 

Looked at the log and I'm now seeing errors with _notify-synch which didn't happen previously.

This SUCKS!

First question: are you absolutely sure this is related to upgrading the app and not to paypal enforcing TLS1.2 for the live system which began a couple of weeks ago?

Secondly, when you look at the errors in the paypal log, do you just have empty responses? This is usually TLS or SSL related.

If you have Verify SSL set to true in General Options, you will need to update the paypal certificate from the one that comes with the app

Error 4020 is a PDT validation error with paypal. Most likely the token that's set in your osc store doesn't match the one in the paypal account in the environment you're running against (they are different in sandbox and live).

...if you are totally convinced that they match you can submit a ticket to paypal support and they'll tell you exactly what's causing the error code

I have the correct Sandbox credentials.  (FYI, there's no PDT in Sandbox, only NVP/SOAP Sandbox API Credentials.)

Will consider contacting PayPal, once I reset to previous version of PayPal App to reduce number of possible causes.

I re-installed the PayPal App (v5.010) and reactivated Payments Standards.  Still getting the getting the "Could not verify the PayPal transaction. Please try again."  It does not return to the correct checkout_process.php page, but goes back to the Shopping Cart and it shows the items still in it.

Still getting the _notify-synch  Fail (420 code).

BUT,

The payment does go through. I'm also seeing 3x of these entries in my Test Order status now (before I was only seeing 1x entry):

Status:
Preparing [PayPal Standard]

Comments:
Transaction ID: 4DT93903CU839863K
Payer Status: unverified

oh yes there are! They are in exactly the same place as the live ones; you have to log into the paypal account on sandbox.paypal.com and go into website payment preferences under settings.

Makes it seem even more likely your settings are wrong...

pp invents the personal details when you create the account in sandbox

if you can't use it just create a new sandbox merchant account on developer.pp and use that instead - you can have as many as you want

create a new business account in the developer.pp and use the same credentials (copied and pasted via notepad to ensure they are the same) to login sandbox.pp

this definitely works, I just did it

Oh, ok.  Thanks!  Can I reuse the same email address or use a different one?

I also came across this information on the PayPal site:

https://developer.paypal.com/docs/classic/lifecycle/sb_about-accounts/

You can create additional sandbox accounts on the developer site or directly on the sandbox site, https://www.sandbox.paypal.com

Oh, created a new test Business account and was able to login to https://www.sandbox.paypal.com.  Woo Hoo!

Found the Website preferences (under My Selling Tools)!

Reconfiguring and reupdating the information and will run another test.

Order cycle worked with the new Test Account and Test PDT token.  Returned back to site with empty Shopping Cart showing.  No errors in PayPal.

Thank you, Thank you!!!  You were right, it was not PayPal App v5.018 that was the issue.

However, now have other issues:

(1) Test Customer not getting the order notification email.

(2) Not getting the 2nd order notification email (SEND_EXTRA_ORDER_EMAILS_TO) to 2nd email account.

(3) Order status history shows "Preparing [PayPal Standard]", but customer is not notified (used to say Processing with green checkmark).
