Category Search in Yelp is not Filtering properly in nodejs. I have given category as "Restaurants" but my o/p is : parks and Playgrounds

Question

I have been trying to implement the business search in yelp fusion. But I couldn't get the results, I have given the category in order to get filtered code:

            function yelpSearchReuslt(latitude,longitude,radius,listOfResult){
                const searchRequest = {
                    categories:"Restaurants",
                    latitude:latitude,
                    longitude:longitude,
                    radius:radius
                };
                const client = yelp.client(API_KEY);
                client.search(searchRequest).then(response => {
                    const firstResult = response.jsonBody.businesses;
                 })

In the o/p I am getting categories like Playground and parks o/p:

Answer 1

It looks like you've almost got it. You just need to use the identifier for 'categories' rather than the name based upon the documentation for the categories parameter which says:

"The value in parenthesis should be used when specifying a search category input."

In your case use restaurants rather than Restaurants. In your code above change the definition for searchRequest to:

const searchRequest = {
         categories:"restaurants",
         latitude:latitude,
         longitude:longitude,
         radius:radius
      };

Hope that helps!

function yelpSearchReuslt(latitude,longitude,radius,ResultCount){   
                   var request = require("request");
                  var options =
                   {
                    method: 'GET',
                    url: YELP_URL+latitude+"&longitude="+longitude+"&term="+"Restaurants"+"&limit="+ResultCount+"",
                    headers:
                           {
                           authorization:API_KEY
                           },
                    body: '{}'
                   };
                   request(options, function (error, response, body){
                      if (error) {  
                           res.status(400).json({MESSAGE:MESSAGE})
                       }
}

You need to change category to term and edit the answer

function yelpSearchReuslt(latitude,longitude,radius,listOfResult){
               const searchRequest = {
                   term:"Restaurants",
                   latitude:latitude,
                   longitude:longitude,
                   radius:radius
               };
               const client = yelp.client(API_KEY);
               client.search(searchRequest).then(response => {
                   const firstResult = response.jsonBody.businesses;
                })
