I have an url which is https://www.yahoo.com/**75063**/list.json
.
Here I had ApiClient which has base_url as https://www.yahoo.com/
and I'm getting the zipcode of location and can be able to append it. But I'm facing problems to append this url to "/list.json."
Also,the above mentioned url is not working one but just included in post to give better understanding of my question.
