Square: Error Code Generic Decline

What This Means

This error means that Square is declining the customer's payment method because the issuing bank is declining to authorize the card.

Common Causes For This Error

Incorrect credit card number or expiration date
Insufficient funds
The bank declined based on location
The bank's fraud rules blocked the transaction

Note: This type of generic error can be returned in many cases where Square declines the payment. Check within your Square Online Dashboard for specific declines and reports by visiting Reports >> Transaction Status. The Transaction Status report will list any unprocessed transactions – declined cards, canceled payments, and other uncompleted transactions.

Suggested Next Steps

Check the customer's information in your payment gateway to determine if the payment simply needs to be updated or retried (see "After Resolving the Issue" below).
Contact the customer to have them add a new payment method and add it to their Scheduled Order.
Once a new payment method is added to the Scheduled Order, the Scheduled Order should be processed with the new payment method.

Adding A New Payment Method for Your Customer?

If you are adding a new payment method for your customer directly to your payment gateway (manually), ensure that you edit the failed Scheduled Order, add a new payment method, and copy the required billing information from your payment gateway directly to their Scheduled Order including:

Gateway CustomerId
Gateway PaymentId
Billing Address
Payment Method Description (optional, but strongly suggested because it is used to display the payment method to your customer)

After Resolving the Issue

Once this issue is resolved, you should use the action to Restart Processing the Failed Scheduled Order.
