Posts and Comments

We provide many routes to list posts of a user or a company, retrieve comments on those posts, retrieve who liked a post, like a post or a comment, or comment a post directly. You can also use search to find posts with specific keywords and filters.

LinkedIn uses multiple IDs for the same post. It is important to use the social_id of the post on all action and interaction calls to be 100% reliable. You can get it from the list of posts of a user, or, if you only have the URL of a post, take the post ID from the URL, use the retrieve-post route with that ID, and take social_id from the result to list or add any comment or reaction.

Example from URL

For the following post URL that contains activity before the ID: https://www.linkedin.com/posts/postpress_nocode-automation-solopreneurs-activity-7332661864792854528-hcGT.

You need to retrieve the ID part in the URL 7332661864792854528 to perform a retrieve-post request.

For URLs that contain ugcPost (linkedin.com/posts/xxx-ugcPost-7336013677930006817-6jfq) use this format: urn:li:ugcPost:7336013677930006817.

For URLs that contain share (linkedin.com/posts/xxx-share-7336013677930006817-6jfq) use this format: urn:li:share:7336013677930006817.

curl --request GET \
  --url 'https://api.postpress.ai/api/v1/posts/7332661864792854528/?account_id=7ioiu6zHRO67yQBazvXDuQ' \
  --header 'X-API-KEY: {YOUR_ACCESS_TOKEN}'

In the result you need to use "social_id": "urn:li:activity:7332661864792854528" to add or list a comment or reaction. Example: post a comment on this post.

curl --request POST \
  --url 'https://api.postpress.ai/api/v1/posts/urn:li:activity:7332661864792854528/comments' \
  --header 'Content-Type: application/json' \
  --header 'X-API-KEY: {YOUR_ACCESS_TOKEN}' \
  --data '{
  "account_id": "7ioiu6zHRO67yQBazvXDuQ",
  "text": "Hey"
}'

      "name": "John Doe",
      "profile_id": "ACoAASss4UBzQV9fDt_ziQ45zzpCVnAhxbW"
    }
  ]
}'
