List comments on an ad

Lists the comments on an ad's post, including dark posts that never ran organically, so you can moderate ad engagement.

Useful for moderating or analyzing engagement on dark posts (ad creatives that never went live organically), which the regular GET /v1/inbox/comments/{postId} endpoint cannot serve because dark posts are not in Zernio's post database.

An ad that runs on both Facebook feed and Instagram feed has two separate underlying posts with separate comment threads (the creative's effective_object_story_id and effective_instagram_media_id). Use the placement query param to pick one; with no param the Instagram side is returned when it exists, otherwise Facebook. The identifiers are read from the ad record (persisted during sync) with a Marketing-API fallback for ads that predate the field.

Comments can land on extra posts Meta creates for placement variants, which the creative does not report. On Instagram, every media a comment.received for this ad arrived on is read too; on Facebook, every dark post matched to this ad by its copy. They are merged newest first. With more than one post, pagination.cursor is a Zernio cursor covering all of them: pass it back unchanged.

For Instagram-placed comments, the Instagram account that runs the ad must be connected to Zernio, because those comments are read through that account's token. If no connected Instagram account on the profile can read the ad's media, the call returns ads_connection_required (the Facebook side, if any, is still readable via ?placement=facebook).

TikTok uses the connected TikTok Ads advertiser token and supports both paid video ads and Spark Ads. since and until select a date window of at most 30 days; the default is the last 30 days. TikTok searches by ad group, so Zernio filters each page to this ad. A page can be empty while pagination.hasMore is true. Reuse pagination.cursor with the same limit; the cursor retains the date window. placement is Meta-only and returns a 400 for TikTok. Listing needs no identity or video item ID. When the ad group is stored, each page makes one comment-list call and no ad-detail lookup, including for external ads that TikTok no longer returns from ad details. meta.tiktokItemId: null does not prevent listing. If the ad group is missing, Zernio fetches ad details; unavailable details return 404 ad_not_found, and no ad group returns 400 ad_not_commentable.

TikTok returns replies as separate comments with parentId; nested reply fetching is not supported. canReply requires a first-level comment, comment-management permission, a video item ID and a supported TT_USER or CUSTOMIZED_USER identity. canDelete requires TikTok's own-comment deletion capability, a video item ID and a supported identity. Both flags are false when identity or item is unknown. Listing uses stored and comment-specific fields without fetching identity. A direct reply or delete request can lazily resolve missing fields and succeed even after a false flag. canHide is true because visibility changes need only advertiser and comment IDs. canLike is false. Use the ad comment reply, hide and delete operations below to moderate TikTok comments. Other platforms return feature_not_available.

Requires the Ads add-on. Response shape matches GET /v1/inbox/comments/{postId}.

The {adId} path segment accepts any identifier dialect Zernio indexes for the ad: Zernio internal _id (24-char hex), the numeric platformAdId (the value shipped in comment.received webhooks as comment.ad.id), or the creative's effective_object_story_id / effective_instagram_media_id. Caller doesn't need a translation step.
