问题
It's possible to retrieve first level contacts of one of my LinkedIn contacts using LinkedIn API.
If i pass one of my contacts name or email, it is possible to retrieve his/her first level contacts, i'm using PHP as my development platform.
Help is highly welcome!
回答1:
You can only search for 2nd level/degree connections with the People Search API, and you need approval before you can use it. There is no way to get a full list of all 2nd level connections without search parameters.
Search for "facets" in the API docs, especially with the value "S" (Second Degree Connections).

The profile fields for the LinkedIn API are documented here: https://developer.linkedin.com/documents/profile-fields
As you can see, connections are not available for second degree (or further) connections, only for the logged-in and authenticated user.
