Instagram User Follower Scraper

Collect available Instagram follower lists and profile details for audience research and account analysis. Export usernames, display names, profile links, pictures, verification and privacy status, with a collection summary for every requested account.

A valid Session ID is required. Blank, missing, or whitespace-only Session ID fails the run. Instagram may expose only a subset of an account's followers; a finished collection does not guarantee a complete follower list.

Features

• Collect available follower lists and a profile summary for each requested account. A valid Session ID is required.
• Process up to 10 accounts and set a follower limit for each account.
• Export results and check saved totals and incomplete collections for every requested account.

How to Use

1. Enter 1–10 Instagram usernames, @handles or profile URLs.
2. Paste a valid Instagram Session ID (sessionid cookie). This field is required.
3. Optionally set Max Followers Per User, such as 20.
4. Start the Actor, then open the Dataset and Collection Summary. Check each account's status before using the results.

Input example

{
  "usernames": ["nasa"],
  "sessionId": "REPLACE_WITH_YOUR_SESSION_ID",
  "maxFollowers": 20
}

Replace the placeholder before starting. The Actor verifies the signed-in connection. Blank, missing, or whitespace-only Session ID fails input validation. An invalid or rejected Session ID also fails the run; it does not switch to a public-profile-only mode.

Input

Field	Description
usernames	Required list of 1–10 accounts. Accepts usernames, @handles and Instagram profile URLs. Repeated usernames are collected once; every entry must be valid.
sessionId	Required secret input. A valid Instagram sessionid cookie. Blank, missing, or whitespace-only values fail the run.
maxFollowers	Whole number from 0 to 100000, per account. Default 0 continues while followers are available, within the run allowance. Profile rows are additional results.

A run can save at most 100,000 rows in total, including profile rows. A requested follower limit is a maximum, not a promised number of results. Collection may stop earlier because of account visibility, unavailable data or the run's allowance. Setting 0 does not guarantee access to all followers. To avoid continuing indefinitely, collection stops with partial results after three consecutive pages add no new follower identities. This safeguard does not mean later pages contain no additional followers.

Finding your Session ID

In a signed-in Chrome tab at Instagram, open Developer Tools → Application → Cookies → https://www.instagram.com. Copy the value named sessionid into the Actor's Session ID field.

Treat this credential like a password. Use only an account you control and keep the value private. If Instagram requires a security check, complete it on Instagram before trying again. Copy a fresh Session ID from your signed-in browser before each run. Use a secondary account rather than your main account, and avoid frequent or concurrent runs. Instagram may identify automated activity and restrict the account. A fresh Session ID does not remove those risks or guarantee access. The Session ID is marked as secret input and is not included in result rows or the collection summary.

Output

Each collected account can produce one profile row and multiple follower rows. sourceUsername identifies the requested account; username identifies the account described by that row. Accounts that cannot be collected may have no rows; consult their summary status.

The Actor uses pay-per-event billing. Both saved profile rows and saved follower rows count as billed results. maxFollowers limits follower rows only. Check the Actor's current pricing before starting; this page does not quote rates.

Every row contains these same 14 fields:

Field	Meaning
item_type	profile or follower.
sourceUsername	Requested account, normalized to lowercase.
username	Account described by the row, normalized to lowercase.
userId	Verified account identifier, kept as a string.
fullName	Display name in its original language, or null.
biography	Available source profile biography; null on follower rows.
profileUrl	Instagram profile link for the row's account.
profilePicUrl	Available HTTP(S) profile picture link, or null. Links may expire.
isVerified	true, false or null when unknown.
isPrivate	true, false or null when unknown.
followerCount	Available profile follower count, or null; always null on follower rows.
followingCount	Available profile following count, or null; always null on follower rows.
index	Saved follower position within this source account, starting at 1; null on profile rows. This is not an Instagram ranking.
scrapedAt	Collection time as an ISO 8601 timestamp.

Unknown values stay null; they are not converted into false or zero. Counts are nonnegative whole numbers when known. Text preserves the original language, including Unicode characters. followerCount is a profile snapshot, not the number of follower rows saved by this run.

Collection Summary

Collection Summary opens the OUTPUT record. It contains status, the mode (always followers for successful collection under this Session-required Actor), requestedUsers, savedRows, savedProfiles, savedFollowers, requestCount and a users entry for each requested account.

Each account entry contains username, status, savedProfiles and savedFollowers. Optional followerPages counts follower pages read across restarts. Optional incompleteRecords: true means some returned records could not be verified and were omitted.

Account status	Meaning
private	A profile was collected, but its follower list was not collected because the account is private.
complete	The available follower collection reached its end. This does not prove every follower was visible.
limit_reached	The requested follower limit was reached.
partial	Some requested collection remains incomplete. Saved results are retained.
pending	This account has not yet been collected.

For a partial follower list, users[].stopReason provides a reason when one was established:

Reason	Meaning
source_limited	Instagram explicitly limited the visible list and supplied no further page.
continuation_unavailable	Instagram did not supply consistent information for collecting more results.
continuation_repeated	Instagram returned a continuation that was already visited.
safety_limit	Collection reached an internal safety allowance.
reported_count_mismatch	The list ended before the profile’s reported follower count was matched. The cause of the difference is unknown.
unverified_records	Some returned records could not be verified.

An absent reason does not imply a complete list. Check the account status and run status too. Verified results remain available when Instagram restricts a list.

The overall status is complete, partial, failed or budget_reached. Overall complete can include accounts marked private or limit_reached; read the per-account statuses. A successful platform run can still contain a partial collection. The summary distinguishes saved data from requested work and should be checked alongside the Dataset.

FAQ

Why did I receive profiles but no followers?

Session ID is required; blank Session ID fails validation rather than collecting profiles only. When OUTPUT.mode is followers, check the account status (private, partial, limit_reached), availability and run allowance. A profile row alone does not demonstrate that follower collection completed.

Why are there fewer follower rows than the profile's follower count?

Instagram can limit which followers are visible to a session. Your limit or the run allowance can also stop collection. The Actor reports the available subset and collection status; it does not infer missing follower accounts. A partial result describes this collection attempt. It does not establish a fixed Instagram-wide limit or prove that another account or interface would show the same list.

Can it collect private accounts' followers?

Follower lists for accounts identified as private are not collected. Available profile details may still be returned. This Actor does not bypass account privacy controls.

What happens if my Session ID is blank or invalid?

Blank, missing, or whitespace-only Session ID fails input validation. An invalid or rejected Session ID is also an error; the Actor does not fall back to a public-profile-only mode. Check your signed-in session and resolve any security check on Instagram.

Are missing flags and counts reported as false or zero?

No. Unknown values are null. Rows without a verifiable account identity are omitted rather than filled with another account's details.

Does starting a new run automatically continue an earlier run?

No. A new run is separate. When the same run restarts with its saved storage, the Actor verifies saved progress before continuing. Saved partial results remain available; progress that cannot be verified stops continuation.

Can I use the output in other tools?

Export the Dataset or use the Actor API in workflows that accept structured data. No particular third-party integration is implied.
