    Square: Why did it suddenly start showing payment error when trying to submit form?

    Asked by waddell on April 04, 2017 at 05:06 PM
    This form has been enabled and functional for months. Now we are getting complaints of this error appearing when you try to make a payment, we only have one product for sale (after you hit submit). I tried myself & got this message twice. To my knowledge, no one has changed anything on the form or in our Square account. Did something break somewhere? It's not the payment being declined or anything...we have tried this with multiple cards, computers, browsers, etc. Same error. Either the card_nonce or Customer_card_id mest be set .

    I've checked your form and I can see the same error when trying to submit the form, I've cloned your form deleted all fields and conditions, but the issue is still there. 

    This will be forwarded to our second level so our developers can take a deeper look to the issue, seems an isolated issue with that form since I've tested the Square integration on another form and it works without any problem. 

    We will let you know as soon as we receive any update about it.

    The problem was caused by the total calculation—it was not calculating properly due to the lack of a base tax rate in your payment settings.

    We have just released a patch that should fix this problem. 

    Apologies for any inconvenience caused.
