问题
My main problem is getting the token. I can’t go further than this step.
In the Linkedin API's docs there are two ways described to obtain the token. Witch is the correct one?
1) https://developer.linkedin.com/docs/v2/oauth2-client-credentials-flow 2) https://developer.linkedin.com/docs/oauth2#configure
I understand that in order to use the new Linkedin API (the partners one) I should use the first one (https://developer.linkedin.com/docs/v2/oauth2-client-credentials-flow)
Here is my petition:
https://www.linkedin.com/oauth/v2/accessToken?grant_type=client_credentials&client_id={MYCLIENTID}&client_secret={MYCLIENTSECRET}
The response: Error "access_denied" error_description "This application is not allowed to create application tokens"
And I get stuck here.
With the second one (https://developer.linkedin.com/docs/oauth2#configure) I actually get a token: https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id={MYCLIENTID}&redirect_uri={MYURIREDIRECT}&state={STATERETURNED}
This returns the code (and the State) which I use to make the token request:
https://www.linkedin.com/oauth/v2/accessToken?grant_type=authorization_code&client_id={MYCLIENTID}&client_secret={MYCLIENTSECRET}&redirect_uri={MYURIREDIRECT}&code={CODERETURNED}
And I get the token. But this isn’t the correct way to do it, is it?

By default you will need to use the authorization_code flow to obtain an access token. Per the documentation the client_credentials flow is not enabled by default and needs to be specially enabled by LinkedIn.
