LinkedIn offers a version 2 of the API that includes connections, member rich content, profiles, and marketing developer platform as endpoints. LinkedIn is the world's largest business social networking hub. Launched in 2003, LinkedIn has millions of users and is implemented in over 200 countries. One purpose of the site is to allow registered users to maintain a list of contact details of people with whom they have some level of relationship, called Connections. Users can invite anyone (whether a site user or not) to become a connection. The LinkedIn API is a RESTful platform that provides a simple, consistent representation of people, companies, jobs, and the interactions and relationships between them. Our query language lets you read data in XML and JSON at the granularity and aggregation that you choose. Use OAuth 1.0a to authorize users and begin making REST API calls using any programming language.The API’s access is restricted to authorized developers.
After a lower court ruled that HiQ was within its rights to circumvent LinkedIn’s API program by “scraping" LinkedIn’s Web pages, a US Court of Appeals upheld the ruling and paved the way for irreparable harm to the API economy. What this means for the future of the API economy remains to be seen.
Which APIs are the most popular with developers? There are a lot of ways to come to an answer; this month we are using our directory data to offer one. Every API in our directory has a track functionality and by looking at the data we can see which APIs our readers have shown the most interest in.
At the end of last year, LinkedIn announced major changes to its APIs and developer program. Those changes will soon take effect, and developers need to migrate accordingly by March 1. New developer program features, version 2 of its API, and the use of OAuth 2.0 will all be requirements on March 1.
