How do I find the rules used to pre-authorize credit cards?

It's part of your business model. Free trials and other incentives are offered to encourage new customers to subscribe to your services.  As part of the process, free-trial'ers must be pre-authorized by providing their credit card information to give your services a try.

But what happens when pre-authorization fails? What are the payment gateway checks and validations used during pre-authorization process? 

Solution

Your payment gateway provider defines the fraud prevention policies  that validates credit card information during the credit card authorization process. These validations can vary among gateway providers. Common validations can include address verification, expiration dates,  to name just a few. The following are key points that can assist  with pre-authorization:

Payment Gateways Validate Payment Method Data

Zuora relies almost exclusively on the payment gateway to validate the payment method data, with the following exceptions:

  • Zuora only validates that the Expiration Date on the credit Card Payment Method type is not in the past. Contact Global Support if you want to have this validation disabled.
  • Zuora Payment Pages 2.0 provide greater validation options.
  • Other payment methods have standard field length restrictions.
Nonempty Payment​​​ Methods Fields are Passed to the Gateway for Validation

Zuora passes all nonempty payment method fields to the gateway for validation, including the method's billing address, IP address, and so on.

Contact your payment gateway provider or check their website. They should be able to provide you with their fraud prevention policies.

Gateway Option Fields can be Passed for Additional Fraud Checking

Zuora can pass in additional fields, called Gateway Options, to a gateway. These fields enable you to pass additional data for fraud checking or other gateway-specific functions.
