Service Integration - Service Method: How can I add dynamic data to GET parameters?

I’m using a web service through a Service Integration model & REST Connector element. I want to consume a web service which has a dynamic parameter as a list. This is the definition of this webservice:

<WebService Endpoint>/users/<id>/search?ids[]=1&ids[]=2&…&ids[]=10

As you can see, the ids parameter, is a dynamic list which holds multiple integer values. Now, reading the manual, it indicates that GET parameters should be enclosed in wildcards “{}”, but in this case, the parameters couldn’t be entered manually. How can I achieve this?
