Implementing auto-post in linkedin using spring boot

Question

I am implementing auto-post feature in linkedin using spring boot and oauth2. I have created the app in linkedin and the permissions it request are r_liteprofile, w_member_social. I am able to get access_token but when i am sending POST request to https://api.linkedin.com/v2/ugcPosts along with the token then the server is responding with 403 Forbidden status. What am i doing wrong? Does we need any more permission than r_liteprofile, w_member_social to post in linkedin?

    TokenResponse tokenResponse = gson.fromJson(token, TokenResponse.class);
    String post_url = "https://api.linkedin.com/v2/ugcPosts";
    HttpPost wallPost = new HttpPost(post_url);
    ArrayList mediaList = new ArrayList();
    wallPost.setHeader("Content-Type","application/json");
    wallPost.setHeader("Authorization","Bearer "+tokenResponse.getAccess_token());
    wallPost.setHeader("X-RestLi-Protocol-Version","2.0.0");

I have used HttpClient to send the request along with above headers.

The following image shows the token and permissions.

There is nothing wrong with the OAuth token as if there was the response would be 401 (https://developer.linkedin.com/docs/v2/oauth2-client-credentials-flow)

I think you need to add 'w_share' scope to your application. Current scopes do now allow posting updates to LinkedIn. See details here: https://docs.microsoft.com/en-us/linkedin/shared/references/migrations/default-scopes-migration
