Master Client Index (MCI) Web Service Interface

To support an electronic interface between the immunization registry (such as VacTrAK) and the Master Client Index (MCI), MultiView, a web service is available at <context path>/soa/getPatientListingRequest/getPatientListing.wsdl. This web service allows user accounts with the PHC-Hub Run Web Service Export permission to query the registry for all patient demographic updates that have occurred since the last time a query was made from that account. Optionally, a date can be passed to the web service causing the query to return all updates that have occurred since that date rather than since the last time a query was made.
