To use such an API, simply register your APP on LinkedIn developers and create a script that will perform http requests for get the site data ( More details in the documentation itself ).
Fortunately, there is a python module that acts as an abstraction layer, which allows us to save time by avoiding coding the request scripts again. The module name is python-LinkedIn , and is available for download through the pip.
Example of official documentation
from linkedin import linkedin
API_KEY="wFNJekVpDCJtRPFX812pQsJee-gt0zO4X5XmG6wcfSOSlLocxodAXNMbl0_hw3Vl"
API_SECRET="daJDa6_8UcnGMw1yuq9TjoO_PMKukXMo8vEMo7Qv5J-G3SPgrAV0FqFCd0TNjQyG"
RETURN_URL=" link "
authentication = linkedin.LinkedInAuthentication (API_KEY, API_SECRET, RETURN_URL, linkedin.PERMISSIONS.enums.values ())
print (authentication.authorization_url)
application = linkedin.LinkedInApplication (authentication)
The values that should go into the API_SECRET and API_KEY variables are informed to you as soon as you perform the registration of your APP (These are unique values and should only be used by you in a specific project.)
