title: I am trying to download data from REST API to azure data lake via azure data factory. How can I pass query parameters for API in azure data factory?
body: <p>I am doing this using ‘Copy Activity’. Is there any other activity that can better perform this operation?
  Example REST API URL:<a href="https://xzy.com/servicename?name=tom&amp;age=50&amp;city=boston&amp;" rel="nofollow noreferrer">https://xzy.com/servicename?name=tom&amp;age=50&amp;city=boston&amp;</a>......
  I am putting '<a href="https://xzy.com/servicename/" rel="nofollow noreferrer">https://xzy.com/servicename/</a>' as the base URL for the linked service.
  How to pass the query parameters 'name=tom' and 'age=50' and 'city=boston' to the base url in the azure data factory to get the response? 
  Will the parameters be passed at linked service, dataset or pipeline level?</p>
