copied!<p>Use the <a href="http://www.yelp.com/developers/documentation/v2/search_api" rel="nofollow">search API</a> instead, and set a <code>category_filter</code> according to <a href="http://www.yelp.com/developers/documentation/category_list" rel="nofollow">this list</a>.<br> This should give you all the "objects" in the given category.</p> <p>Something like this <code>http://api.yelp.com/v2/search?category_filter=restaurants</code>.</p> <hr> <p><strong>Update</strong></p> <p>It seems like I misunderstood a little... so you want to get the root category.<br> (eg. for "italian"–>"restaurants", "french"->restaurants, "car dealers"->automotive etc.)</p> <p>I think you have two options:</p> <ol> <li>Hardcode the dictionary of all restaurant subcategories (french,italian...) into a file (plist, json, whatever) and after getting the "object" you could check if the subcategory is included in the hard-coded subcategories dictionary.</li> <li>Use the search API and provide the bussiness <code>id</code> and <code>category_filter</code> set to restaurants and check if it returns any result - if not, then the object is not in the right category.</li> </ol> <p>The reason why I am suggesting to hard code it is, because Yelp doesn't provide an API to get complete list of categories.</p> <p>In my opinion I would try the approach #1, because it is less intensive on the network side and a dictionary is blazing fast.</p> <p>But to answer your initial question, no it is not possible to have the root category in the JSON file.</p>
