Question: We’re trying to integrate your callback URL feature for high volume searches. Do you have any samples for how the URL should be sent by us (i.e. does it include any unique identifiers like search ID or is it a generic API that can be used in all callback scenarios)? Also do you have any samples of a post-back that we will receive through our API our so we can anticipate the format and determine which high volume search we are retrieving?
