Square Payment Module for Zen Cart [Support Thread]

[DrByte]

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.

What are your settings for configuration->credit cards?

Hi mc123455678
I have the following:

Credit Card Enable Status - VISA 1
Credit Card Enable Status - MasterCard 1 Info
Credit Card Enable Status - AmericanExpress 1 Info
Credit Card Enable Status - Diners Club 1 Info
Credit Card Enable Status - Discover Card 1 Info
Credit Card Enable Status - JCB 1 Info
Credit Card Enable Status - AUSTRALIAN BANKCARD 0 Info
Credit Card Enable Status - SOLO 0 Info
Credit Card Enable Status - Debit 0 Info
Credit Card Enable Status - Maestro 0 Info
Credit Card Enabled - Show on Payment 2 Info

Square confirmed that this restriction in the E-Commerce API is for Japan, specifically when creating a Square account in Japan. And that it might be elsewhere too.
Therefore the only cards capable of being used with the web input method (typing in the card information) are VISA, MasterCard, and American Express.

They say that use of JCB, Diner's Club, and Discover Card can be accomplished using the invoice method, which I understand is quite a bit more expensive to use.
English:
1. https://squareup.com/help/us/en/arti...nvoices-online
Fee seems to be 2.9% + 30c
for Card on File 3.5% + 15c
2. https://squareup.com/help/us/en/arti...es-with-square

Japanese (different conditions):
1. https://squareup.com/help/jp/ja/arti...nvoices-online
Fee seems to be 3.25% (JCB 3.95%)
for Card on File 3.75% (JCB 3.95% [same as standard fee])
2. https://squareup.com/help/jp/ja/arti...es-with-square
Has a note at the top stating that support for JCB, Diner's Club, Discover Card depends on the shop (presumably whether the application has been approved).

So Square clearly operates differently in different regions/countries.

Yes: this is based on regulatory approvals that are granted by local banking rules.
Every card-processing service needs to get approvals, which takes time.

This made me wonder. Having only ever used Square and PayPal EC to process credit cards, I've never looked at that configuration page - even after all these years.

Delving into the code I believe that only Authorize.net & PayPal Website Payments Pro use the checks set on that page and that they have no bearing on how Square processes payments.

The cc_validation logic that uses those settings is not used by the Square module because Square does all the card-validation itself, offsite, not in ZC.
