title: 403 forbidden error with spring boot API call?
body: <p>I am trying to consume a REST API using Springboot. Now, I have tested the api from Postman and everything seems to work fine but when I call the api through POSTMAN. I am getting a 403 forbidden error. The API returns the response in JSON format and I tested through POSTMAN and everything seems to be working fine,.</p>
  
  <pre><code>Through Postman, I am adding headers as key-value and its a get request
  "user-key": "*********"
  </code></pre>
  
  <p>Spring boot:-</p>
  
  <pre><code>public String getdata(){
          String url = "https://developers.zomato.com/api/v2.1/categories";
  
          RestTemplate rs = new RestTemplate();
          HttpHeaders headers = new HttpHeaders();
          headers.add("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36");
  
         // headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
          headers.setContentType(MediaType.APPLICATION_JSON);
          headers.set("user-key", "*********");
          String consumeJSONString =  rs.getForObject(url, String.class);
  
  
          return consumeJSONString ;
  
  
  
  
  
  
      }
