  1. [GET,POST,PUT,PATCH,DELETE], represent different types of requests that clients can make to interact with a server.
    • The GET method is used to retrieve data from the server. GET requests are read-only and should not have any side effects on the server or the data.
    • The POST method is used to submit data to the server to create a new resource.
    • The PUT method is used to update an existing resource on the server.
    • The PATCH method is used to partially update an existing resource on the server. Unlike PUT, a PATCH request only includes the changes that need to be applied to the resource, not the entire resource representation.
    • The DELETE method is used to request the removal of a specified resource from the server.
  2. For the HTTP request, you can either select a sample query from the menu at the left in number 3, which fills in the query field, or you can choose to manually type your request in the field.
  3. Sample queries that you can use in part 2″ the query field”.
