PayPal 10413 error

[Monsz]

That commented code is content many "if" structures, so that code isn't good for us. We need unset the subtotal values always, so the best way if you insert the three rows, what i wrote:)

Thanks for the clarified code.. and it's not that I am not grateful.. but I still want to understand something.. I found this commented out code in BOTH PayPal files

/*  //PayPal API spec contradicts itself ... and apparently neither of these "requirements" are enforced. 
    //Thus skipping this section for now:

    // according to API specs, these cannot be set if they contain zero values, so unset if they are zero:
    if ($optionsST['TAXAMT'] == 0)      unset($optionsST['TAXAMT']);
    if ($optionsST['SHIPPINGAMT'] == 0) unset($optionsST['SHIPPINGAMT']);
    if ($optionsST['HANDLINGAMT'] == 0) unset($optionsST['HANDLINGAMT']);
    // set missing subtotals if they are zero values, since all must be submitted
    if (!isset($optionsST['TAXAMT']))      $optionsST['TAXAMT'] = 0;
    if (!isset($optionsST['SHIPPINGAMT'])) $optionsST['SHIPPINGAMT'] = 0;
    if (!isset($optionsST['HANDLINGAMT'])) $optionsST['HANDLINGAMT'] = 0;
*/

Wouldn't un-commenting this code be the SAME/SIMILAR as what you are suggesting I do to modify to these files???

Got it.. I'll give your fix a try.. Nothing else works.. and you fix makes logical sense considering that this is a totaling error or some sort..

Any news?

The fix resolved the problem in the webshop what i created.
The shop's running properly for three weeks, there was many transactions via paypal, and everything is ok :)

Any news?

I am actually doing some tests right now. So far so good. Great job finding this Monz. Will let you know if the fix seems resolute in a moment.

Testing Completed
Test performed with PayPal Developer Sandbox accounts.
Test used 3 Accounts, 3 Products, 3 Attributes, 3 price ranges, and 3 different sized items.

• Test Account 1
  
  • Purchased Product A: Succeeded
    
    • Price $1077.49
    • Attribute D
    • Large Sized Item
    
    
  
  
• Test Account 2
  
  • Purchased Product B: Succeeded
    
    • Price $592.61
    • Attribute C
    • Medium Sized Item
    
    
  
  
• Test Account 3
  
  • Purchased Product C: Succeeded
    
    • Price $183.16
    • Attribute A
    • Small Sized Item
    
    
  
  

So three different tests with three different items varying by hundreds in price, shape and weight, and attributes, yet all of them worked! I think this might be it Captain!

Nothing seems to be a problem for Zen Cart to communicate to PayPal now. Everything seems functional. If a few others can also confirm this works, I think this would be the most resolute fix. All the other ones I tried only worked for some people or continued to have random errors later on.

Good job mate!

If you leave out those values, what happens to the receipt issued by PayPal?

[DieuxSoldat_04]

Hey Doc,

No difference really. Just displays the total the store displays at checkout. I included an image just in case this isn't the receipt . Sandbox accounts use fake email addresses so I'm not sure if it is the receipt but I did log in to the Sandbox Buyer account and click on "Details" for the test purchase.

Supposed Receipt.

Let me know if it seems right.

- Jason

Edit:

To me, as long as the right amount is charged and the total is the same as indicated on my store, then it's ok with me, heh.

Also, I was wondering, PayPal charges a percentage of the transaction as a fee right? Then would it be possible to make the Zen Cart add that charge to all PayPal payments or have the PayPal account itself do it so the customer is charged the fee? I probably won't do it but would be nice to know, ; ].

This fix worked perfectly for me

Thanks very much

What I did was: In paypaldp.php (Paypal Website Payments Pro class) insert this code to the rows 1301-1303, in paypalwpp.php (Paypal Express Checkout) insert to the rows 1519-1522:

    unset($optionsST['TAXAMT']);
    unset($optionsST['SHIPPINGAMT']);
    unset($optionsST['HANDLINGAMT']); 

The modified code will like this in both files:

    // subtotals have to add up to AMT
    // Thus, if there is a discrepancy, make adjustment to HANDLINGAMT:
    $st = $optionsST['ITEMAMT'] + $optionsST['TAXAMT'] + $optionsST['SHIPPINGAMT'] + $optionsST['HANDLINGAMT'];
    if ($st != $optionsST['AMT']) $optionsST['HANDLINGAMT'] += strval($optionsST['AMT'] - $st);


        //**************inserted code for unset subtotals********************************************************************
    unset($optionsST['TAXAMT']);
    unset($optionsST['SHIPPINGAMT']);
    unset($optionsST['HANDLINGAMT']);
        //*********************************************************************************************

/*  //PayPal API spec contradicts itself ... and apparently neither of these "requirements" are enforced. 
    //Thus skipping this section for now: 

I suggest you, before make the change, backup both files, if you make mistake, you can upload the original files.

Thanks Monsz, it worked perfectly when all the other solutions failed. You have made me very very happy!!
