Using Chargebee and BlueSnap
Chargebee uses Spreedly, a third-party card vault, to store the customer's card information. If you are using BlueSnap's services already, you will have to migrate your customer's card information to Spreedly to start using Chargebee with BlueSnap. Contact firstname.lastname@example.org for more information about the migration process.
