`list_post_comments`

List the comments on one post, or the replies to one comment.

This action only reads. It changes nothing, so it is safe to try.

What you give it

On LinkedIn, click the More icon (the three dots) at the top right of the post, then "Copy link to post".

What you get back

When it worked, the answer is { "ok": true, "result": { … } }. Inside result:

`returned`	number
`nextCursor`	A cursor. Other actions take it.
`comments[].id`	A comment id. Other actions take it.
`comments[].postId`	string
`comments[].postUrn`	string
`comments[].threadId`	string

A field that does not apply to an answer is left out, or is null. There are 4 more fields nested inside these.

When it did not work, the answer is { "ok": false, "error": "…", "message": "…" }. What each error means.

Good to know

authorDetails.id is not documented as any kind of id; use authorDetails.profileUrl to reach the person.
