What happens if a customer has already signed up directly with the merchant?

Scenario:

• You use the Bango Resale API to create an entitlement for a customer, but they've already signed up with that merchant and aren't eligible for your offer

In some cases, the merchant can notify Bango that the customer isn't eligible. If so, Bango can pass this notification to you using the Notification URL provided as part of the API request to create the entitlement.
