How it works

1. auth — Extracts LinkedIn cookies via CDP Network.getCookies.

2. my-feed — Calls voyagerFeedDashMainFeed GraphQL query to fetch your personalized LinkedIn home feed. Filters out ads/promotions.

3. feed — Calls identity/profileUpdatesV2 with q=memberShareFeed to fetch a specific user's posts. Returns text, engagement metrics, and activity URNs.

4. details — Calls feed/updates/<activityUrn> for the full post including author info, text, linked articles, reshare data, and engagement breakdown.

5. comments — Calls voyagerSocialDashComments GraphQL endpoint with the post's socialDetailUrn. Returns comment text, author, like count, and reply count. Supports pagination.

6. reactions — Calls voyagerSocialDashReactions GraphQL endpoint to list who reacted, with their name, headline, and reaction type.

7. like — POST to voyagerSocialDashReactions?threadUrn=<activityUrn> with {"reactionType":"LIKE"}. Supports all 6 LinkedIn reaction types.

8. unlike — Calls the voyagerSocialDashReactions GraphQL mutation to remove your reaction.

9. comment — POST to voyagerSocialDashComments with the comment text and thread URN.

10. like-comment / unlike-comment — Same reaction GraphQL mutations as posts, but with a comment-specific threadUrn format: urn:li:comment:(activity:<activityId>,<commentId>).

11. reply — POST to voyagerSocialDashComments with both threadUrn (activity) and parentCommentUrn (the comment being replied to).

12. repost — Calls voyagerFeedDashReposts GraphQL mutation with the original post's rootContentUrn (share URN). Fetches post details first to resolve the share URN.

13. repost-with-thoughts — POST to feed/shares with commentary text and resharedUpdate reference to the original share URN.
