    I would pull the files, manually pull the SQL entries and start over installing the stock module. Then sync it with new credentials in your Square account.

    That forces everything to be new replaced and working.

    Alternately, check to see there were no changes with your provider. Recently a customer lost module function due to the 'new - upgrade' server having cloud Php settings that shut important functions off the site was using.

    That fixed it. I tested it. Thanks!

    Looking to switch to Square from 2checkout. Any advice? Pro vs. Cons? 2checkout worked well for us for a while until we run into a stolen Credit Card problem, and lost over $500. It turns out that 2checkout stopped providing phone support just recently, which adds salt to the wounds. Are there any other good processors similar to them besides Square to look at? TIA.

    Hi

    Using 156c.

    I've just had a complaint about a payment going through twice on the same order.

    Sure enough there are two payments.

    In my logs I found the following -

    "Card nonce already used; please request new nonce."

    Based on my brief research of this error,

    some can be found here - https://www.sellercommunity.com/t5/D...ard/td-p/27378

    can I assume perhaps that the customer managed to refresh the screen (or go back) and trigger the payment twice?

    I wonder if we need to add a script to disable the button after one click. Historically on sites where this has been enabled, folks still find a way to refresh or go back and forward (because they are impatient or have super high speed connections) and the problem repeats of 'double clicking the send request'.

    Also, this error will display when there is a javascript interfering as mentioned previously - see post #364 in this thread:

    DrB,
    i'm sorry. this is just not correct.

    with the exception of card present transactions using an EMV chip card and reader, it is the MERCHANT who assumes all risk for the credit card transaction. one could get an AVS response of EXACT match, and the card holder could still report the transaction as fraudulent and it is the merchant who would suffer the loss for the transaction. in addition, AVS is primarily for US addresses although there seems to be some work getting done on some international addresses.

    i have not used square (or the square module for ZC), but in my experience in credit card transactions, the response is a single character code, that corresponds to zip match, zip street number match, etc. the MERCHANT could choose to reject transactions that do not meet their criteria for the transaction. issuing banks can reject transactions for any number of reasons. but getting an EXACT avs response does not transfer the liability for the transaction to the issuing bank. the liability for any card not present transaction rests with the merchant.

    finally, considering that square does provide AVS verification, i find it odd that the API would not provide that information back to the merchant making the transaction. and apparently they do not. from their site:

    avs_status
    string
    Status code returned from the Address Verification System (AVS) check. Can be AVS_ACCEPTED, AVS_REJECTED, AVS_NOT_CHECKED.

    pretty lame that they do not provide the response code from the AVS system.

    The Square plugin v1.0 has been released.
    https://www.zen-cart.com/downloads.php?do=file&id=156

    The 1.0 module now uses Square's latest 2020 API SDK version 3.20200226.0

    Also, transaction "notes" now include not just the customer name but also abbreviated order details, up to 500 characters.

    NOTE: IF YOU WERE USING THE 1.00-BETA version, this is DIFFERENT, so you will want to upgrade from 1.00-beta to actual 1.0 using the posted zip linked herein.


    Upgrade instructions:
    Delete the server's /includes/classes/vendors/square directory
    and the /includes/modules/payment/square_support directory
    (You will replace these in a moment, but this deletes older obsolete files first).
    Then upload all the files from the files_to_upload directory, putting them into the same directory on the server as you find them in the zip.
    And if you'd copied the jscript_square.php file to an alternate checkout flow, do that copy again.

    NOTE: Upgraders will be required to re-authorize to your Square account manually within 30 days after installing this module.
    (You can force it sooner by Removing and Re-Installing the module in your Admin, re-adding your credentials, etc.)

            $p = '';
                for ($i = 0; $i < sizeof($order->products); $i++) {
                    $p2 = $order->products[$i];
                    if (!$p == '') {
                        $p .= ', ';
                    }
                    $p .= '(' . $p2['qty'] . ') ' . $p2['name'] ;
                }
            }
            $p = 'Item(s) Ordered:' . $p;
            
            $d = 'Delivery Address: ' . $order->delivery['street_address'] . ', ' . $order->delivery['city'] . ', ' . $order->delivery['state'] . '  ' . $order->delivery['postcode'] . '  tel:' . $order->customer['telephone'];
            $p .= '; ' . $d;
    
            $note = htmlentities(trim($order->billing['firstname'] . ' ' . $order->billing['lastname'] . ' ' . $p . ' ' . STORE_NAME));
    After reviewing it, I figured it makes sense to incorporate this too, so (a modified form of) this is now in v1.0.

    bug Re: Square Payment Module for Zen Cart [Support Thread]

    Okay, I found a bug in the 1.0 beta. It is in includes\modules\payments\square.php line 664:

    Code:
            $oauthApi = new SquareConnect\Api\OAuthApi($this->_sqConfig);
    The OAuthApi class initializes NOT with SquareConfiguration, but rather with ApiClient. See lines 34-45 of includes\classes\vendors\square\connect\lib\Api\OAuthApi.php:

    Code:
        /**
         * Constructor
         * @param \SquareConnect\ApiClient|null $apiClient The api client to use
         */
        function __construct($apiClient = null)
        {
            if ($apiClient == null) {
                $apiClient = new ApiClient();
                $apiClient->getConfig()->setHost('https://connect.squareup.com');
            }
      
            $this->apiClient = $apiClient;
        }
    So this is the error that is being thrown by this bug. This is the problem I have been experiencing:

    Code:
    [15-Mar-2020 20:47:11 America/Chicago] PHP Fatal error:  Uncaught Error: Call to undefined method SquareConnect\Configuration::callApi() in C:\wamp\www\store\includes\classes\vendors\square\connect\lib\Api\OAuthApi.php:134

    #9 {main}
      thrown in C:\wamp\www\store\includes\classes\vendors\square\connect\lib\Api\OAuthApi.php on line 134
    I believe I fixed it by modifying line 664 to:

    Code:
            $oauthApi = new SquareConnect\Api\OAuthApi($this->_apiConnection);
