A universal matching service is a service that can use any of your match rules to perform matching and can accept any input fields. The service takes a match rule name as an input option, allowing you specify the match rule you want to use in the API call or web service request. The service does not have a predefined input schema so you can include whatever fields are appropriate for the type of records you want to match. By creating a universal matching service you can avoid having separate services for each match rule, enabling you to add new match rules without having to add a service.
This procedure shows how to create a universal matching service and includes an example of a web service request to the universal matching service.
You now have a universal match service that you can use to perform matching using any of the match rules defined in the Match Rules Management tool in Enterprise Designer. When calling the service, specify the match rule in the MatchRule option and specify the input fields as user-defined fields.
