Zero-Amount Authorizations

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.
