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

    Zen Cart 1.5.6c
    PHP Version: 7.3.18
    Database Engine: MySQL 5.5.5-10.3.23-MariaDB
    Square Payments 1.1

    I have been getting a number of square payment failure messages with the code "GENERIC_DECLINE". I am getting some payments through as well. Was wondering If this is an intermittent site issue or User error.

    Any Advice welcome

    GENERIC_DECLINE is the square equivalent of "oops!"

    "An unexpected error occurred" is certainly not a lot of help.

    First, make sure your API is dated 04-22-2020.

    Then, if the module's Log Mode is not set to notify you of errors, select at least log on failures.

    Next, try dropping the PHP back a notch just to make sure your 7.3 is not just outside the current range of 1.5.6c

    Just in case, check server logs for the times these failures occurred. With everyone using the internet at home, you may have some dropped connections.

    Keep in mind, that some of these transactions might be someone just testing to see if a hacked card will work.

    Thanks for that.
    I have seen cvv failures which could be people testing cards.
    The last lot were the same person at 03:00 so I would not expect internet to be busy. Prior to that it took someone 2 attempts but the order was successful on the second attempt.
    I have logging on as suggested and I am using the latest version of Square api.

    As for Php are you suggesting I go down to 7.2?
    I have not had any php errors using zen cart. I did have to change a few arrays to make sure they were defined for counts so not even getting warnings.
    Happy to try 7.2.

    Is there any logging i can turn on with Square outside of zen cart?

    Thanks again

    Someone else might have other suggestions but, that's all I've got in my bag of tricks.

    Being such a vague error, it may be best to just move on. We've only had one GENERIC_DECLINE reported by our square-using customers.

    As v1.1 says 'Integrated using SquareConnect PHP SDK 3.20200325.0' is it safe/advisable to always be using the latest API?

    Generally best to use the API version that the module was built for. That said, the module transmits its API version with its transaction requests, so it should auto-negotiate with Square for the right one to use on each communication attempt.

    None of our clients with square have had problems with the current api. Several have had problems that were cured by updating.

    Would be interested to hear other experiences along these lines.
    We have been using the Square module (still using 0.97) since January 2020, and it is indeed very convenient because of its seamless integration into the checkout page, unlike, say, Paypal.

    There is a major shortcoming though: At least in Japan there is the following restriction, notice of which we received from their support staff after several INVALID_CARD transaction failures.

    Online use via the E-Commerce API only permits transactions for 3 credit card types: VISA, MasterCard, American Express.

    The following additional 3 card types can only be used physically, via the Square Reader (card reader): JCB, Diner's Club, Discover Card.

    So the use of the module is sadly quite limited for online transactions. I am still waiting for confirmation as to whether this is a regional restriction for Japan, or a world-wide Square restriction. It is confusing since in one's Square account one needs to make a special application for JCB use approval, which we made and received the OK for, but there is no mention that one cannot actually use JCB and related cards with the E-Commerce API.

    Zen Cart 1.5.6c modified to support Japanese language (postage module support work in progress). Upgraded incrementally each version from initial 1.5.5d.
