What happens if an activation URL expires before the customer is redirected to it?

Scenario:

1. You create an entitlement which requires the customer to activate the service with the merchant
2. The Bango Resale API returns an entitlement in state PENDING and asks you to redirect the customer to a particular URL
3. You redirect the customer to the URL, but a timeout has occurred and the activation URL is no longer valid

In this case, the customer sees an error message on the merchant page. The customer must restart the activation flow themselves.
