php – Searching the LinkedIn API without authorizing a user

Posted by: admin July 12, 2020 Leave a comment


Im currently creating a PHP application that searched various Social Media and analyses the results. Now im stuck at calling the LinkedIn API.

I need to call these API’s without user authentication (I need a sort of app authentication). Facebook offers a way to retrieve an access token, based on app key and secret. With Twitter I simply used my own accestoken en access secret.

I searched all day for a way to call the LinkedIn API in a similar way, but havent succeeded in finding one. I also couldn’t find my own access token en secret on the LinkedIn developer’s site.

Do you know how I can access the LinkedIn API from my PHP application, without the user having to login himself?

Hope you guys can help me out!

How to&Answers:

The LinkedIn API doesn’t support non-user-authenticated requests – that is, there are no calls for which you can just use the consumer key and secret – they all require a user token and secret as well.

The LinkedIn API is designed to be used from the member’s perspective, acting on behalf of a specific member – it’s not designed to support general application search use cases.

Like Twitter, you could use your own access token, but per the LinkedIn guidelines, you can’t show anyone the information that you pull unless you use a token obtained on their behalf.
