Instagram — comment/getMany

When to Use

Bulk comment moderation: After publishing a high-visibility post, retrieve all comments for batch sentiment scoring, flagging policy violations, and routing to the appropriate moderation action nodes.
Community management dashboard: Pull all comments on recent posts to populate a community manager's inbox, sorted by timestamp, with unanswered questions highlighted.
Contest or giveaway entry collection: For promotions that ask followers to comment to enter, retrieve all comments from the giveaway post and process entries for winner selection.
Post engagement reporting: Collect comment text from campaign posts for quantitative and qualitative reporting — word frequency, sentiment distribution, question extraction.
Keyword-triggered response: Periodically scan new comments for specific keywords (discount codes, support requests, competitor mentions) to trigger automated workflows.

Node Policies & GuardRails

Rate limit: 200 calls per user per hour. High-engagement posts may have hundreds of comments across many pages. Use large limit values (100) and implement pagination loops efficiently.
GDPR: Comment text and usernames are personal data. Obtain lawful basis for processing and implement data retention policies when storing comment data.
Hidden comments: The API returns all comments including hidden ones. Filter by the hidden field if you only want to process visible comments.
Deleted comments: Comments deleted by the author or by you after retrieval will not update in cached responses. Re-fetch for current state.

Examples

Giveaway entry collection

{
  "resource": "comments",
  "operation": "list",
  "accessToken": "{{ $credential.instagram.accessToken }}",
  "igUserId": "{{ $env.IG_USER_ID }}",
  "mediaId": "{{ $input.giveawayPostId }}",
  "limit": 100
}

Retrieves up to 100 comments per page. The next node loops through comments array entries to extract username values for the prize draw, paginating via paging.after until the cursor is empty.

Keyword moderation scan

  "igUserId": "17841400000000000",
  "mediaId": "{{ $trigger.body.value.mediaId }}",
  "limit": 50
}

Triggered when a post receives a new comment via webhook. Retrieves recent comments and pipes them through a keyword filter node that routes policy-violating comments to comment/hide.
