# Facebook Post Comment Replies API (https://www.socialcrawl.dev/platforms/facebook/post-comment-replies)

> 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.

TL;DR: `GET /v1/facebook/post/comment/replies` costs 1 credit per call and returns SocialCrawl's unified JSON schema. Single x-api-key auth, 100 free credits on signup.

## 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. |

## Code example

```bash
curl "https://www.socialcrawl.dev/v1/facebook/post/comment/replies?feedback_id=ZmVlZGJhY2s6MzM3MzYxMzI5OTQ4Nzc1NV8xOTI5NTk0OTE3Njg3MTcz&expansion_token=MjoxNzc4NjM1MDM3OgF_JaMa3kMP9RIWC" \
  -H "x-api-key: sc_YOUR_API_KEY"
```

## FAQ

### How 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.
