How to setup cfhttpparam that takes multiple values?

[2Charlie]

I'm a doing a json calls via a third party's API and in one of its url_hash paramters, they gave me this example.

json -- url_hash: { '$in' : ['office-365', 'office-excel', 'office-tutorials', 'office-products'] }

So here's my current http request.

<cfhttp url="https://app.example.com/api/head/category.json" method="get" timeout="15" throwonerror="false" proxyServer="webproxy.example.com" proxyport="8080">
  <cfhttpparam type="url" name="_authbykey" value="56a7d8c532131c40581235487">
  <cfhttpparam type="url" name="project_id" value="55c4ffd4567891c527e294fe6">
  <cfhttpparam type="url" name="limit" value="1"/>
  <cfhttpparam type="url" name="url_hash" value="#hash#"/>
  </cfhttp>

So, will line 5 of my code above work in this case? Or, do I  have to do something different?

Thank you.
