List replies to a LinkedIn comment

Lists the replies under one LinkedIn comment, oldest first, each with its author, text, time, reaction breakdown and ext.is_submitter (true when the reply is by the post's author). Called without cursor it returns the whole thread. Called with the parent's ext.previous_replies_token as cursor it returns only the replies older than the newest one, which /v1/linkedin/post/comments already carries in comment.replies, so the two calls together are the thread with no overlap. Pass the parent comment's comment.id, or its comment.ext.urn, as comment_id; the urn is the faster route on posts published as images, video or documents. A thread read without cursor takes about 20 seconds, and up to about 30 on the first comment of such a post when only the bare id is passed.

Request

Base URL: https://www.socialcrawl.dev/v1
URL: https://www.socialcrawl.dev/v1/linkedin/post/comments/replies
Auth: API key in header x-api-key

Query parameters

urlstring required

Full URL of the LinkedIn post. It has to carry the post's ACTIVITY id, either https://www.linkedin.com/feed/update/urn:li:activity:<id> or https://www.linkedin.com/posts/<slug>-activity-<id>-<code>. A urn:li:share: or urn:li:ugcPost: URL names a different id for the same post and is rejected with a 400 before any credits are charged, because it cannot be resolved to the post. Every endpoint that lists posts publishes the activity form as post.url, so copy that field rather than rebuilding the URL from post.id, which is not always the activity id.

comment_idstring required

The parent comment's comment.id from /v1/linkedin/post/comments, or its comment.ext.urn (urn:li:comment:(ugcPost:<post>,<comment>)).

cursorstring

LinkedIn cursor.

sincestring

Only rows published on or after this date: YYYY-MM-DD (midnight UTC) or an ISO 8601 timestamp. Rows older than it are left off each page. This list is not in date order, so the walk does not stop at the date: keep following next_cursor, and each page costs what a page costs even when every row on it is filtered out. A row with no date is kept. published_after, start_date, from_date, publish_time (yesterday, this-week, this-month, last-3-months, last-6-months) and max_age_days are accepted and applied as since.

untilstring

Only rows published on or before this date: YYYY-MM-DD (that whole UTC day is included) or an ISO 8601 timestamp. Newer rows are left off each page and the walk does not stop, so older pages follow. A row with no date is kept. published_before, end_date and to_date are accepted and applied as until.

Headers

Cache-Controlstring

Send no-cache to bypass the response cache and force a live fetch. Billed at the normal endpoint cost; the fresh result is written back to cache for the next caller. Only the no-cache directive triggers this. See the Response Schema guide for details.

Idempotency-Keystring

Optional UUID that makes the request safely retriable. The key is reserved atomically per account before billing. A concurrent retry receives 409 IDEMPOTENCY_IN_PROGRESS with a Retry-After of 1 second while the original is young, growing to a quarter of the time it has been running (at most 30); a crashed reservation expires after 5 minutes. A replay keeps the cached payload immutable except for billing metadata: credits_used becomes 0, idempotent_replay becomes true, and credits_remaining is refreshed to the current balance. A known current balance appears in both the body and X-Credits-Remaining header; no balance row resolves to 0. On a transient lookup failure, body credits_remaining is null and X-Credits-Remaining is omitted. Completed outcomes expire after 24 hours. If the claim store is unavailable, the request fails closed before billing. GET endpoints do not combine idempotent replay with Server-Sent Events: use Accept: application/json when sending this header. The unsupported key-plus-SSE combination is rejected before billing.

Response

Successful response

successboolean required

Whether the request succeeded

platformstring required

Platform name

endpointstring required

API endpoint path

credits_usedinteger required

Number of credits consumed

credits_remaininginteger nullable required

Current account balance, or null when this response could not establish one. Free cache hits always return null because they do not establish an authoritative post-request balance. An idempotency replay also returns null when its current-balance lookup fails. It is never a fabricated zero, so a zero here means the account really is empty. The authoritative reading is the one on a billed response, which comes straight from the deduction.

request_idstring required

Unique request identifier for support

cachedboolean required

Whether the response was served from cache

idempotent_replayboolean

True only when this response is an idempotency replay
