Get post comments
Fetch comments for a specific post. Requires accountId query parameter.
On Facebook, passing a COMMENT id as postId is also supported and returns that comment's replies instead of the post's top-level comments. Instagram does not support this and returns 400: its replies come nested in each comment's replies array, with no separate paging. YouTube does not support it either, postId must be a video id.
Responses are cached for up to 10 minutes, so a page may lag new comments by that window. Do not poll this endpoint for real-time updates: subscribe to the comment.received webhook, which delivers new comments as they arrive. Your own writes (creating, replying to, or deleting a comment) refresh the cache immediately.
TikTok is served for accounts connected through the TikTok for Business app: postId is the TikTok video id, each top-level comment carries up to three inline replies, and commentId pages the full reply list of one comment. Developer-app TikTok accounts return 400 with code PLATFORM_LIMITATION.
Hidden comments: Facebook Pages and Instagram accounts connected through Instagram Login return them with isHidden: true. Instagram accounts connected through Facebook Login do not return them at all (Meta omits them, together with their replies), so a hidden comment and a deleted one look the same on this read.
Path parameters
Zernio post ID or platform-specific post ID. Zernio IDs are auto-resolved. LinkedIn third-party posts accept full activity URN or numeric ID. On Facebook, a comment ID is also accepted here and returns that comment's replies (not supported on Instagram).
Query parameters
(Reddit only) Subreddit name
Maximum number of comments to return
Pagination cursor, returned by a previous call as pagination.cursor. This is the platform's own opaque paging value passed through verbatim: never construct, decode or validate it client-side.
