First of all we need an end point and Postman tool. That end point will look like http://www.abc.com/name . So name will call as an ‘end point’. By using ‘name’ end point at last in URL it will give the full detail of any person whose name will pass at the place of ‘name’ .
Suppose i will pass the name ‘xyz’ then i can get the full detail of xyz (if API was developed to provide full detail by using ‘name’ end point).
