Zero-Amount Authorizations {#recur-bill-zero-auths}
===================================================

When you create a subscription before the subscription start date, `Cybersource` verifies the account with a zero-amount authorization to ensure that the stored card details are valid.  
When you create a subscription on the subscription start date, `Cybersource` does not perform a zero-amount authorization because the first recurring payment is processed immediately.

> IMPORTANT
> **Deprecated flow:** This behavior occurs only when you do not provide the value for subscriptionInformation.originalTransactionId and application performs the initial authorization. This flow does not ensure Strong Customer Authentication (SCA) compliance.
