### Intro
Creating your own LinkedIn Job RESTful API can be an amazing way to build customized job openings applications, or even build a service around the data you’ve collected, or it can fairly be a fun personal project that allows you to learn a new skill.

An API is an acronym for **_Application Programming Interface_**.

It is a set of functions or procedures that serves as an interface for connecting an application's services, data and functionalities with other independent service providers, operating systems etc.

While this may seem like an intimidating task at catch of a glimpse, it’s actually in every aspect easy.

### Requirements
To gain access to this API, we will need:

- A LinkedIn Account and Working page 
- Python 3 programming language 
- A terminal or Code editor

The LinkedIn API provides a service that lets people take their LinkedIn profiles and networks with them to other sites or applications via an [OAuth](https://oauth.net) based interface.

### What you can use LinkedIn Jobs API for

The LinkedIn Jobs API can be applied in the following cases and more:

- Job postings crawling
- Create and manage jobs
- Promote jobs
- Manage jobs lifecycle
- Job openings and career analysis and many more.

By the end of this tutorial you will be able to do and understand the followings:

1. How to get access to LinkedIn Jobs API
2. Install the python3-LinkedIn library for working with LinkedIn APIs
3. Perform LinkedIn Developer Authentication
4. Fetching a list of jobs.
5. Getting job details
6. Discover the limitations of LinkedIn Jobs API and more.

### Getting Started
To get started, we first need to acquire an API secret key from LinkedIn. This is very easy to do! 😎. By following the steps below, you should be able to get your LinkedIn API credentials.

Visit the [LinkedIn Developer web page](https://developer.linkedin.com/)

1. Click on the **create app**

It’s Important you have a LinkedIn page associated with the app. In case you don’t have any page on your LinkedIn, don’t sweat it, you can create one by clicking on the **Create a new LinkedIn page** button below.

2. Click on Auth and under the **_Application credentials_** card you will find your Authentication keys.

Easy isn’t it? 😀

Now, you have been able to acquire your API secret keys, next is to install necessary python libraries that will aid in this our operation.

### Install the Python libraries

Run the code below on your terminal or command prompt to install the [python3-linkedin](https://pypi.org/project/python3-linkedin/) library.

```pip install python3-linkedin```

The library can as well be downloaded and compiled using the following commands:
```
## First clone the repository
git clone https://github.com/DEKHTIARJonathan/python3-linkedin.git

## Then install the library
python setup.py install
```

This library provides an interface to the LinkedIn Profile, Group, Company, Jobs, Search, Share, Network and Invitation REST APIs.

The LinkedIn REST API supports the [OAuth 2.0](https://oauth.net/2/) protocol for authentication.  

### Quick Usage From Python Interpreter
To quickly test the library using an python interpreter, you can do that comfortably from the test server.

```
from linkedin import server
application = server.quick_api(KEY, SECRET)
```
This will print the authorization url to the screen. Go into that URL using a browser to grant access to the application. After you do so, the method will return with an API object you can now use.

### Job Search API
The Job Search API enables search across LinkedIn’s job postings. You can get more information from here.

```
application.search_job(selectors=[{'jobs': ['id', 'customer-job-code', 'posting-date']}], params={'title': 'python', 'count': 2})
{u'jobs': {u'_count': 2,
  u'_start': 0,
  u'_total': 206747,
  u'values': [{u'customerJobCode': u'0006YT23WQ',
    u'id': 5174636,
    u'postingDate': {u'day': 21, u'month': 3, u'year': 2013}},
   {u'customerJobCode': u'00023CCVC2',
    u'id': 5174634,
    u'postingDate': {u'day': 21, u'month': 3, u'year': 2013}}]}}
```
### Jobs API
The Jobs APIs provide access to view jobs and job data.

```
application.get_job(job_id=5174636)
{u'active': True,
 u'company': {u'id': 2329, u'name': u'Schneider Electric'},
 u'descriptionSnippet': u"The Industrial Accounts Sales Manager is a quota carrying senior sales position principally responsible for generating new sales and growing company's share of wallet within the industrial business, contracting business and consulting engineering business. The primary objective is to build and establish strong and lasting relationships with technical teams and at executive level within specific in",
 u'id': 5174636,
 u'position': {u'title': u'Industrial Accounts Sales Manager'},
 u'postingTimestamp': 1363860033000}
```

You can also fetch you job bookmarks.
```python
application.get_job_bookmarks()
{u'_total': 0}
```
