Additional API Field Required for Any Credit or Debit Card Subscription {#rb-subs-migration-4-script-reqts-card-1-any}
======================================================================================================================

If the subscription is for a credit or debit card, the subscription creation request must include the *network transaction ID* of the transaction that originally initialized the subscription (and allowed for the storage of payment information).  
Include the network transaction ID in this field of the subscription creation request message:  
subscriptionInformation. originalTransactionId  
For information about obtaining the network transaction ID, see [Obtaining Additional Values Required for Card Subscriptions](/docs/cybs/en-us/recurring-billing/migration/all/rest/recurring-billing-migrate/rb-subs-migration-4-new-subs/rb-subs-migration-4-script-reqts-card-obtain.md "").  
Continue to use this network transaction ID to uniquely identify future automatic payments for this subscription.

> IMPORTANT
> Including the network transaction ID in the subscription creation request obtains the payer's consent for you to make automatic (recurring) payments with the new subscription in the ` Cybersource ` system.
