Udaan Machine Coding :

Goals (completed) :

• Desgined a POST API which creates new user with unique username : As mentioned in the Question, we donot have to create a User authentication. So for Indentification I used username as a identification for the user.

Route : http://localhost:3000/users/

• Designed a POST request API for creating Event :

Route: http://localhost:3000/events/ Required Body:

{
	"event_type": "yoga",
	"capacity":60,
	"start_time":30,
	"duration": 30
}

• Desgined a API for registering the Event :

Cases Handled:

• If user have already registered for the event , they willn't able to register again.
• If event's capacity have exceeded then user push into waiting list
• If event's capacity haven't exceeded then user able to register the event.

Route: http://localhost:3000/events/:eventid/regsiterevent Headers Required :

   username : (since i used username as identification. so it is required)

• Desgined a API by which user can cancel their registeration 30minutes before the event start

Cases Handled:

• User can able to cancel the event 30 min before the event start
• If user can able to cancle then it automatically confirm the registration of the first waiting user into main list if any waitlist user exits.

Route : http://localhost:3000/users/:username/cancelevent

Headers Required:

eventid : (Id of the Event that user want to cancel) (required)
