Overview

Sample Application is a ready-to-use code example that enables you to try out RESTful calls to LinkedIn's APIs. The application provides scalable and customizable code for your requirements as you begin API development with LinkedIn.

The sample application contains the client and server component you can use to manage your requests to LinkedIn's APIs. The server creates and stores your access token and invokes APIs upon request from the client application. You can download or clone the OAuth sample application and try out these APIs.

Note: For a detailed demo, please visit LinkedIn's public documentation page

The sample application uses the following development tools:

Spring Boot: Used as web server framework [https://spring.io/projects/spring-boot]
LinkedIn OAuth 2.0: user authorization and API authentication
Maven: app building and management
Java: SE 7 or later versions are required for development

Prerequisites

Add http://localhost:8080/login to the Authorized Redirect URLs under the Authentication section
Configure the application build by installing MAVEN using Installing Apache Maven
