This article will discuss about how to use LinkedIn API with step-by-step integration guide and full documentation list. Let’s get started!<\/p>\n\n

Overview of LinkedIn API<\/span><\/h2>\n

LinkedIn, as we all know, is the most popular professional channel for connecting people from various services and sectors. And if you want to access data from LinkedIn, then you need to leverage LinkedIn API. Accessing data and information from LinkedIn is many a time needed for business purposes or for developing advanced applications, and hence LinkedIn public API is useful.<\/span><\/p>\n

LinkedIn developer API and key functionalities<\/span><\/h2>\n

In this section, we will discuss LinkedIn developer API and its key functionalities. It will help you to answer your query on Does LinkedIn have an API?<\/span><\/p>\n

    \n
  1. LinkedIn Open API has a protocol that defines the 14 resource methods. Each of the resource methods has its interfaces which are standardized and with the required semantics<\/span><\/li>\n
  2. In LinkedIn API integration, there is a Rest.li protocol which is for supporting query parameters and resource keys<\/span><\/li>\n
  3. In addition to your query on Does LinkedIn have an open API, yes it does and one of the key concepts is the LinkedIn API client libraries which are kept to construct API requests easily.<\/span><\/li>\n<\/ol>\n

    How to use LinkedIn API – step-by-step integration guide<\/span><\/h2>\n

    In this section, we will check the detailed steps on how to use LinkedIn API.\u00a0<\/span><\/p>\n

      \n
    1. For LinkedIn API access, OAuth 2.0 is used for user authorization and user authentication<\/span><\/li>\n
    2. There are two types of LinkedIn rest API authorization flows – Member Authorization which is a 3-legged OAuth and Application Authorization which is a 2-legged OAuth<\/span><\/li>\n
    3. The first important concept of LinkedIn data API integration is to establish the input and output data formats using the following code : <\/span>Content-Type: application\/json <\/span>and in JSON format<\/span><\/li>\n
    4. The next important step is to generate a LinkedIn API key or token with Postman. You need to visit the LinkedIn developer portal and click the \u201cAuth\u201d tab to find out the client id and client secret key.<\/span><\/li>\n
    5. Next under the OAuth 2.0 settings, you need to add the callback URLs – <\/span>https:\/\/oauth.pstmn.io\/v1\/callback<\/span> and <\/span>https:\/\/oauth.pstmn.io\/v1\/browser-callback<\/span>\u00a0<\/span><\/li>\n
    6. Then fork the collections and fork the environments under each collection<\/span><\/li>\n
    7. The environment variables Client id and the Client secret are then entered\u00a0<\/span><\/li>\n
    8. Each collection title must be opened to check its Authorization tab. Click on the \u201cGet new access token\u201d button to authenticate the LinkedIn API connections, and select the grant type and the callback URL. Then specify the Authorization URL and access token URL. Use the environment variables as filled in. Define the scope as per the sample : <\/span>{<\/span>rw_ads,r_basicprofile,w_organization_social,w_member_social,rw_organization_admin<\/span>}<\/span><\/li>\n
    9. When the grant type is Authorization Code, the client authentication code is <\/span>Send client credentials in body <\/span>and when the grant type is Client credentials, the client authentication code is<\/span> Send as Basic Auth header<\/span><\/li>\n
    10. \u00a0<\/span>The Authorization or authentication needs to be identified in the next step and allowed or permitted\u00a0<\/span><\/li>\n
    11. In the next step, the developer LinkedIn API key or access token will be displayed and you must select the \u201cUse token\u201d button to set it up<\/span><\/li>\n
    12. Input and output data formats are a must to be set in JSON format, using the following HTTP content type <\/span>Content-Type: application\/json\u00a0<\/span><\/li>\n
    13. The field projection controls need to be set up to determine the display of an entity\u2019s data while responding to an API request. Some fields within the projections may not be required and can be eliminated. The projections are defined using &fields= as the query parameter and then mentioning the names of the fields expected to be returned by separating via commas.\u00a0<\/span><\/li>\n
    14. API calls need to be made by breaking them up into multiple page results. And this is required when there are a large number of entities to be returned via the API calls. Start and count are the query parameters that help paginate through the API calls’ results. The query is to mention the \u201cstart\u201d value as 0 and the \u201ccount\u201d value as N. For the next page, the \u201cstart\u201d value is mentioned as N, keeping the count value the same, and it goes on. The details of the codes are mentioned in <\/span>here<\/span><\/a>.\u00a0 A sample request:<\/span><\/li>\n<\/ol>\n

      GET https:\/\/api.linkedin.com\/v2\/{service}<\/span><\/p>\n

      1. Query tunneling is essential for LinkedIn rest API assessment. It is used for resolving requests – some requests are with Body and some without Body.\u00a0<\/span><\/li>\n<\/ol>\n
