What data / output can you get?

This instagram hashtag scraper tool pushes one dataset item per post found under each tag. Fields are strictly limited to what the actor extracts and pushes.

Data type	Description	Example value
search_keyword	Normalized hashtag used for the search	"travel"
user_pk	Poster’s Instagram user ID (string)	"1234567890"
username	Poster’s Instagram username	"exampleuser"
id	Media ID (string)	"3141592653589793238"
code	Media shortcode	"C2AbCdEFgH1"
caption	Cleaned caption text (line breaks removed)	"Sunset over the mountains 🌄"

Notes:

• Results stream to the Apify dataset as they’re found. You can download results as CSV or JSON.
• Some values may be empty strings if not provided by Instagram for a given post (e.g., caption may be empty).

Key features

• ⚡ Fast hashtag post collection Uses a lightweight HTTP stack (requests.Session with your sessionid cookie) to fetch Instagram’s hashtag SERP and extract usernames and captions from public posts efficiently.

• 🧾 Bulk input (hashtags or tag URLs) Paste a list of plain hashtags or Instagram tag links into urls and the actor will walk through them automatically — great as an IG hashtag user extractor for campaigns.

• 🎯 Per-hashtag limits Control depth with maxItemsPerQuery to cap how many posts are collected per tag.

• 🔄 Connection resilience with proxy fallback On cloud runs, first pages can appear empty from certain IPs. If proxyConfiguration allows it, the actor can switch from direct to Apify datacenter and then residential routes to keep results flowing.

• ✨ Clean, consistent captions Captions are normalized (whitespace and single “.” lines removed) for better downstream analysis.

• 🗃️ Live dataset output with CSV/JSON export Each post is saved immediately to your dataset so you can monitor progress and export to CSV or JSON at any time.

• 🔐 Flexible session input Accepts a raw sessionid value or a pasted fragment like “sessionid=…”. You can also use the INSTAGRAM_SESSION_ID environment variable.

• 🏷️ URL/hashtag normalization Accepts both Instagram tag page URLs and text (with or without #), and normalizes search_keyword for consistent outputs.

How to use Instagram Hashtag Username Scraper - step by step

1. Sign in to Apify.
2. Open the Instagram Hashtag Username Scraper and click Run.
3. Add hashtags in urls:
   • You can paste plain tags (e.g., “nature”, “#travel”) or full tag URLs like “https://www.instagram.com/explore/tags/nature/”.
4. Paste your sessionId:
   • Copy your Instagram sessionid cookie from your browser and paste it into the sessionId field. The actor accepts the raw value or cookie fragments like “sessionid=…”.
5. Set maxItemsPerQuery (optional):
   • Choose how many posts to collect per hashtag (default is 100).
6. Configure proxyConfiguration (optional but recommended on cloud):
   • Enable Apify Proxy for more stable results, especially at scale.
7. Start the run:
   • The actor warms up your session and begins collecting posts. Rows appear live in the Output dataset.
8. Export results:
   • Go to the Dataset tab to download results in CSV or JSON.

Pro Tip: For unattended runs, you can set the INSTAGRAM_SESSION_ID environment variable instead of pasting sessionId each time.
