NMI: 300 AVS Rejected

What This Means

This means that the billing address on the payment method does not match the billing address on file for their bank account.

You may check for more information on this specific transaction and decline within your NMI web interface by visiting your Transaction Reports (found in Reports >> All Transactions).

Suggested Next Steps

Your customers can update their billing address for their saved payment method or add a new payment method if needed.
You may also choose to add a new payment method for your customer, see "Adding a New Payment Method for Your Customer" below.
Once a new payment method is added to the Scheduled Order, the Scheduled Order should be processed with the new payment method. If the issue persists after the steps above you will need to contact NMI support regarding AVS settings.

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 the payment gateway directly to their Scheduled Order including:

Gateway Customer Id
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.
