What is the correct format for query string and path parameters?

Question

I am using API blueprint to mock a set of real world endpoints and am having trouble combining path and query string parameters.

The real world endpoint has a query string parameter appearing 1st followed by a number of path parameters. I have tired loading this up in https://app.apiary.io but when I do it always moves the query string parameter to the end of the endpoint. What am I doing wrong?
