  13. MarkeTrak: API 101 • Inbound Request Types: • Query List • The Query List service returns a list of issues that match search criteria defined in a Query List request. A market participant typically requests (queries) the system for a list of issues within a certain date range. • Query Detail • The Query Detail service returns all information related to a specific MarkeTrak issue number. • Update • The Update service allows market participants to update (or transition from one state to another) a specific issue in the MarkeTrak system. • Submit • The Submit service allows market participants to create a new issue in the MarkeTrak system.
