403 Forbidden Access to posting shares denied for Linkedin API using python-linkedin library

Question

I'm new to working with the Linkedin API and I'm trying to post to LinkedIn using the python-linkedin library: https://github.com/ozgur/python-linkedin

We use Auth0 for authentication. I can get profile information. However, I get a 403 error when trying to post using the Share API.

Testing get profile in the shell works:

In []: linkedin_api.get_profile()
Out[]:
{'firstName': '*my name*',
 'headline': '*my headline*',
 'id': '*my id*',
 'lastName': '*my lastname*',
 'siteStandardProfileRequest': {'url': 'https://www.linkedin.com/profile/view?id=*CONFIDENTIAL*&authType=name&authToken=*CONFIDENTIAL*'}}

However when I try to post to linkedin:

In []: linkedin_api.submit_share('Test posting
...: from the API I am working on using JSON'
...: , 'A title for your share', None, 'http:
...: //www.linkedin.com', 'http://d.pr/3OWS')

This results in a 403 Client Error

LinkedInForbiddenError: 403 Client Error: Forbidden for url: 
https://api.linkedin.com/v1/people/~/shares?
oauth2_access_token=*CONFIDENTIAL*: Access to posting shares denied

Answer 1

Found out what was wrong.

I needed to add the w_share scope in my auth0 lock so that I'd have access to the linkedin Share api.

here's a link to a question that helped me out: https://community.auth0.com/t/linkedin-w-share-permission/12386/2

I added the connectionScopes param to the auth0 lock options and that solved the issue:

connectionScopes: {
    linkedin: ["w_share"]
}
