mockup

• In manufacturing and design, a mockup, or
  mock-up, is a scale or full-size model of a
  design or device, used for teaching,
  demonstration, design evaluation, promotion, and
  other purposes. A mockup is a prototype if it
  provides at least part of the functionality of a
  system and enables testing of a design.

What is api?

• a set of functions and procedures allowing the
  creation of applications that access the features
  or data of an operating system, application, or
  other service.
• a software intermediary that allows two
  applications to talk to each other. Each time you
  use an app like Facebook, send an instant
  message, or check the weather on your phone,
  youre using an API.
• E.g. The API is accessed from the URL
  http//www.domain.com/api/index.php

5
Api formats

• 3 return types are currently supported
• XML (this is the default)
• JSON
• Serialized PHP
• You can specify the return type you wish to
  receive back from the API by adding the "output"
  query string parameter to your API URL. If you
  want to receive XML then you do not need to
  specify the output as that is the default.
  Example
• /api/index.php?methodrequest.getoutputjson
• The "output" parameter will accept xml, json, or
  php as valid values.

Rest api

• REST means
• REpresentational
• State
• Transfer

10
Rest api (cont.)

• Every resource should support the HTTP common
  operations.
• Resources are identified by global IDs (which are
  typically URIs or URLs).
• REST allows that resources have different
  representations, e.g., text, XML,
• JSON etc.
• Stateless in nature. Excellent for distributed
  system.
• Stateless components can be freely redeployed if
  something fails, and they
• can scale to accommodate load changes.
• This is because any request can be directed to
  any instance of a component.

11
http methods

• The PUT, GET, POST and DELETE methods are
  typically used in REST based architectures. The
  following table gives an explanation of these
  operations

HTTP Methods CRUD Operations Descriptions
POST INSERT Adds to an existing resource
PUT UPDATE Overrides existing resource
GET SELECT Fetches a resource. The resource is never changed via a GET request
DELETE DELETE Deletes a resource
