How to complete the challenge POST /todos JSON to XML

The content-type and accept headers do not need to be the same. API Challenges allows us to send a POST request to create a todo item using JSON but receive an XML response.

POST /todos XML to JSON

Issue a POST request on the /todos end point to create a todo using Content-Type application/json but Accept application/xml

• POST request means we will send information in the body of the message
  • e.g. POST /todos sends to the todos endpoint
• create a todo means that the payload will be valid data to create a todo item
• using Content-Type application/json means that we will set content-type header to application/json and the payload will be in JSON format
• Accept application/xml means add an accept header of application/xml to receive the response in JSON format
• add the X-CHALLENGER header to track progress

Basic Instructions

We can mix different accept and content-types so we can send payloads in one format, and receive responses in another format. This challenge is about sending payload in JSON but having the response in XML.

• Issue a POST request to end point "/todos"
  • if running locally that endpoint would be
    • https://apichallenges.eviltester.com/todos
• The request should have an Content-Type header of application/json
• add a valid payload in JSON format to create a todo item e.g.

   {
        "title": "create todo process payroll",
        "doneStatus": true,
        "description": ""
   }

• add an accept header of application/xml to receive the response in XML format
• The request should have an X-CHALLENGER header to track challenge completion
• The response status code should be 201 when all the details are valid.
• Check the body of the response has XML formatted todo item with full details of the created item
• Check the location header for the REST API call to retrieve details of the created item

Extras:

• try GET the location header URL to return the created todo item
