Reply to an ad comment

Reply to a first-level TikTok ad comment. Requires a TT_USER or CUSTOMIZED_USER identity with comment-management permission. Replies to replies are rejected. The response commentId identifies the new reply. This operation is not idempotent; do not blindly retry an uncertain response.

Unknown identity and video item fields are resolved only when needed for this action, then persisted for reuse. Comment-specific fields take precedence. If TikTok no longer returns the ad needed to resolve identity, 404 ad_not_found directs you to check deletion or archival in TikTok Ads Manager. Listing can still succeed. Unsupported or unavailable identity returns 403 feature_not_available. Denied access to ad details returns 403 insufficient_permissions with reconnect guidance and the upstream platformError.

Requires Ads access. The ad is resolved within the caller's accessible profiles. Before moderation, Zernio verifies that the comment belongs to this ad using TikTok's ad-group comment listing. The default search window is the last 30 days. Use since/until for older comments, with at most 30 days between the dates. Lookups scan at most 2,000 ad-group comments; narrow the date window if exceeded. Meta returns 501 feature_not_available with guidance to use the existing inbox comment endpoints and the account/post IDs from GET /v1/ads/{adId}/comments.
