Threads Replies Scraper with Apify

Extract replies and comments from public Threads posts. Each post typically yields ~20 replies. No login required.

Actor: futurizerush/threads-replies-scraper

Prerequisites

Set APIFY_API_TOKEN in environment. Get a token at console.apify.com/account/integrations.

Execution Flow

Apify runs are asynchronous. Every request follows 3 steps:

Start a run -- POST to the actor API, receive a run ID and dataset ID
Poll until done -- GET the run status, wait for SUCCEEDED
Fetch results -- GET the dataset items (returns a JSON array)

Typical run time: 10-30 seconds per post.

Input Parameters

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | post_urls | array of objects | Yes | Post URLs in [{"url": "..."}] format (requestListSources) | | max_replies | integer | No | Max replies per post. Default: 50. Min: 10, Max: 50 |

Important: post_urls uses requestListSources format. Each item must be an object with a url key, not a plain string.

Complete Example (Python)

import requests, os, time

TOKEN = os.environ["APIFY_API_TOKEN"]
BASE = "https://api.apify.com/v2"

# Step 1: Start the run
response = requests.post(
    f"{BASE}/acts/futurizerush~threads-replies-scraper/runs?token={TOKEN}",
    json={
        "post_urls": [
            {"url": "https://www.threads.com/@zuck/post/DIffiWcJnob"}
        ],
        "max_replies": 20,
    },
)
response.raise_for_status()
run = response.json()["data"]
run_id = run["id"]
dataset_id = run["defaultDatasetId"]

# Step 2: Poll until done
while True:
    status = requests.get(
        f"{BASE}/actor-runs/{run_id}?token={TOKEN}"
    ).json()["data"]["status"]
    if status == "SUCCEEDED":
        break
    if status in ("FAILED", "ABORTED", "TIMED-OUT"):
        raise RuntimeError(f"Run failed: {status}")
    time.sleep(5)

# Step 3: Fetch results (JSON array)
items = requests.get(
    f"{BASE}/datasets/{dataset_id}/items?token={TOKEN}"
).json()

# Separate original post from replies
for item in items:
    if item["item_type"] == "original_post":
        print(f"Original post by @{item['author_username']}: {item['text_content'][:80]}")
        print(f"  likes={item['like_count']} replies={item['reply_count']} views={item['view_count']}")
    else:
        print(f"  Reply by @{item['author_username']}: {item['text_content'][:80]}")
        print(f"    likes={item['like_count']}")

Multiple posts

requests.post(
    f"{BASE}/acts/futurizerush~threads-replies-scraper/runs?token={TOKEN}",
    json={
        "post_urls": [
            {"url": "https://www.threads.com/@zuck/post/DIffiWcJnob"},
            {"url": "https://www.threads.com/@mosseri/post/EXAMPLE123"},
        ],
        "max_replies": 50,
    },
)

Complete Example (bash)

# Step 1: Start the run
RUN_RESPONSE=$(curl -s -X POST \
  "https://api.apify.com/v2/acts/futurizerush~threads-replies-scraper/runs?token=$APIFY_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"post_urls": [{"url": "https://www.threads.com/@zuck/post/DIffiWcJnob"}], "max_replies": 20}')

RUN_ID=$(echo "$RUN_RESPONSE" | jq -r '.data.id')
DATASET_ID=$(echo "$RUN_RESPONSE" | jq -r '.data.defaultDatasetId')

# Step 2: Poll until done
while true; do
  STATUS=$(curl -s "https://api.apify.com/v2/actor-runs/$RUN_ID?token=$APIFY_API_TOKEN" \
    | jq -r '.data.status')
  [ "$STATUS" = "SUCCEEDED" ] && break
  [ "$STATUS" = "FAILED" ] || [ "$STATUS" = "ABORTED" ] && echo "Failed: $STATUS" && exit 1
  sleep 5
done

# Step 3: Fetch results
curl -s "https://api.apify.com/v2/datasets/$DATASET_ID/items?token=$APIFY_API_TOKEN" | jq '.'

Error Handling

| Error | Cause | Fix | |-------|-------|-----| | 401 Unauthorized | Invalid or missing API token | Check APIFY_API_TOKEN | | invalid-input: "do not contain valid URLs" | Wrong URL format -- must use [{"url": "..."}] not ["..."] | Use requestListSources format | | invalid-input: "must be >= 10" | max_replies below minimum | Set max_replies to at least 10 | | FAILED: "post(s) appear unavailable or private" | Post doesn't exist or is private | Verify the post URL is public |

Tips

Results include the original post as the first item (item_type: "original_post"), followed by replies (item_type: "reply").
Use reply_to_username to identify who the reply is directed at.
Use is_liked_by_author to find replies the post author engaged with.
source_post_url links each reply back to its parent post (useful when scraping multiple posts).
Threads typically provides ~20 replies per post.
No login or session ID required.
All field names use snake_case (e.g. text_content, like_count, reply_count).
