Facebook Post Comment Replies API
Scrape Facebook Post Comment Replies data with one API call. Returns the reply thread for a single Facebook comment. Both `feedback_id` and `expansion_token` come from the parent `/v1/facebook/post/comments` response: note that `feedback_id` is NOT the comment ID. Forward the returned cursor for additional pages.
Last updated October 2026Maintained by the SocialCrawl team
Returns the replies under a single Facebook comment, each with the author name, reply text, like count, and creation time.
Use it after post/comments: pass that response's feedback_id and expansion_token, which are not the comment id.

What can you do with the Post Comment Replies API?
The Post Comment Replies endpoint gives you structured Facebook data with computed fields in a single request. No scraping infrastructure to build or maintain.
Example Request
curl -H "x-api-key: YOUR_API_KEY" \
"https://www.socialcrawl.dev/v1/facebook/post/comment/replies?feedback_id=ZmVlZGJhY2s6MzM3MzYxMzI5OTQ4Nzc1NV8xOTI5NTk0OTE3Njg3MTcz&expansion_token=MjoxNzc4NjM1MDM3OgF_JaMa3kMP9RIWC&label=purchase_intent"import requests
response = requests.get(
"https://www.socialcrawl.dev/v1/facebook/post/comment/replies",
params={
'feedback_id': 'ZmVlZGJhY2s6MzM3MzYxMzI5OTQ4Nzc1NV8xOTI5NTk0OTE3Njg3MTcz',
'expansion_token': 'MjoxNzc4NjM1MDM3OgF_JaMa3kMP9RIWC',
'label': 'purchase_intent',
},
headers={"x-api-key": "YOUR_API_KEY"},
)
data = response.json()const response = await fetch(
"https://www.socialcrawl.dev/v1/facebook/post/comment/replies?feedback_id=ZmVlZGJhY2s6MzM3MzYxMzI5OTQ4Nzc1NV8xOTI5NTk0OTE3Njg3MTcz&expansion_token=MjoxNzc4NjM1MDM3OgF_JaMa3kMP9RIWC&label=purchase_intent",
{
headers: { "x-api-key": "YOUR_API_KEY" },
},
);
const data = await response.json();Parameters worth sending
label=purchase_intentMarks each comment that shows buying intent, at no extra credits; sentiment, question and complaint are free too.
Parameters
| Parameter | Required | Description |
|---|---|---|
| feedback_id | Yes | `feedback_id` from `/v1/facebook/post/comments` for the parent comment (this is NOT the comment ID). |
| expansion_token | Yes | `expansion_token` from `/v1/facebook/post/comments` for the parent comment. |
| cursor | No | Cursor returned by the previous response for pagination. |
| label | No | Optional CSV of SocialCrawl labels to add to every comment: sentiment, spam, question, purchase_intent, complaint, toxic, low_quality, injection. Without this param every page already carries sentiment, question, purchase_intent and complaint, free; label= adds the labels you name to them (the defaults keep running). Each comment gains computed.labels with probabilities (0 to 1), so you choose the cut-off; a comment that could not be judged carries labels: null. sentiment, question, purchase_intent and complaint are free when asked for too; spam, toxic, low_quality and injection add 1 credit per started 25 newly judged comments (comments already labelled for anyone are free, and so is a cached page). injection flags text that addresses an AI system and tries to direct it (flagged, p); it never drops or rewrites a row. judgments=off (or label=none) turns the default labels off. data.labels reports what was judged and billed. |
| exclude | No | Optional CSV (spam, low_quality), only with the same preset in label. Drops comments whose probability is 0.8 or higher and lists their ids in data.labels.dropped_ids. A comment that could not be judged is never dropped. |
| judgments | No | Optional, on (the default) or off. By default every row gains free SocialCrawl judgments (computed.labels, and computed.relevance on search endpoints), reported in data.labels (mode default) and data.relevance (origin default), each with a status (complete, partial or skipped) and pending: the rows still being judged when the page was sent, which carry null now and are filled on your next call or cached read. Default judgments never add credits, never change an existing field, and never drop or reorder a row. off returns the page exactly as before, with none of those keys. label=none does the same. (on | off) |
| dry_run | No | Optional. When 1, return a cost preview for this labelled or relevance-filtered request without fetching the page or judging any row. data.estimate reports rows_expected, rows_cached, label_credits_min, label_credits_max and base_credits. 0 credits charged. (1) |
| label_evidence | No | Optional, only with label=. When 1, every labelled row also carries computed.labels_evidence.<preset> = { quote, sentence_index }: the sentence in the row that most clearly shows the label, copied verbatim. Absent or null when no single sentence shows it. (1) |
| fit | No | Optional. When goal, keep the rows and fields needed for the goal you pass in goal= (plus any that are uncertain, and the first and last), and replace the rest with a stub. data.held_back lists the held ids and a recall id that re-reads the full page from cache at no extra charge. Without this param the page is unchanged. (goal) |
| goal | No | Required by fit=goal. What you are trying to do, in your own words, up to 300 characters. |
| fit_tokens | No | Optional, only with fit=goal. Soft cap on how much of the page to keep, in tokens. Uncertain blocks and the first and last block are kept even if they exceed it. |
| since | No | 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`. |
| until | No | 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`. |

}FAQ
Have a question? We got answers
Find answers to frequently asked questions about SocialCrawl's API, pricing, and capabilities.
Contact usHow do I get the replies to a Facebook comment?
Send a GET request to /v1/facebook/post/comment/replies with a feedback_id and an expansion_token. SocialCrawl returns the nested replies under that specific top-level comment, each with author, text, like count, and timestamp.
Where do feedback_id and expansion_token come from?
Both come from the /v1/facebook/post/comments response. Each top-level comment there carries its own feedback_id and expansion_token. Take those two values for the comment you want to expand and pass them to this endpoint to pull its reply layer.
How much does the comment replies endpoint cost?
Each request costs 1 credit on the standard tier. New accounts start with 100 free credits and no credit card, so you can expand 100 reply threads before paying. The response is a single synchronous JSON payload.
How do I paginate through a long reply thread?
Pass the optional cursor parameter to walk deeper into a comment with many replies. Each response returns the next cursor; keep calling until it comes back empty. SocialCrawl handles the underlying pagination tokens for you.
Why call this instead of the top-level comments endpoint?
/v1/facebook/post/comments returns top-level comments with a reply count but does not expand the nested layer. This endpoint fills that gap, letting you reconstruct full comment threads for community-sentiment pipelines and conversation analysis.
