Getting Zillow Information from ColdFusion

I recently needed to create some ColdFusion code to call into Zillow so I thought it would be worth sharing.

 

The first thing you will need is an ID from Zillow to give you access to the http services.  They use the term web services but they are really http services.  You can find out everything you need to know about getting started and the Zillow APIs here: <a href="http://www.zillow.com/howto/api/APIOverview.htm" target="_new"> Getting Started with Zillow</a>

 

Once you have your ID you can enter it into the below code and test it on your site.

 

I posted a demo here: <a href="http://www.supportobjective.com/demos/zillowtest.cfm" target="_new">DEMO</a>

         <h3>Zestimate Range:  From #lz# to #hz#</h3> <a href='#request.zillow.searchresults.response.results.result.links.homedetails.xmltext#'

       <hr />

All the other Property Details<br />

<cfdump var='#request.zillow#'>

    <cfelse>

     Zillow could not recognize address

    </cfif>

</cfif>

</cfoutput>
