Like post
Like (or react to) a post as a connected account. Supported platforms: LinkedIn,
X, Facebook, YouTube, Bluesky, and Instagram in limited release (see below).
Threads, TikTok and Pinterest
expose no like endpoint in their APIs and return 400. Reddit returns 400 too,
pointing at POST /v1/accounts/{accountId}/reddit-vote, which covers upvote,
downvote and clear on both posts and comments.
The account does not have to be the one that published the post, which is what
makes executive engagement possible: pass an exec's accountId and the brand
post's ID. postId accepts either a Zernio post ID or the platform's native post
ID. A Zernio post ID resolves to the entry for accountId, falling back to the
post's single entry on the same platform (two entries on that platform is a 400,
so pass the native ID).
LinkedIn requires the w_member_social_feed / w_organization_social_feed
scopes, which are not retroactive: accounts connected before those were requested
get a 403 with code linkedin_reconnect_required until the user reconnects the
account. YouTube spends 50 quota units per call.
Instagram is in LIMITED RELEASE and not generally available: the call needs
instagram_manage_engagement, which Meta has so far granted this app only under
Standard Access, so it works for app admins, developers and testers of our Meta app
and returns a 403 with code PLATFORM_BETA_RESTRICTED for every other account.
That restriction lifts when Meta App Review grants Advanced Access; the constraints
below apply once it does.
Instagram covers feed images, reels and carousels (stories and private-account
media are not likeable). Only an account connected through Facebook Login can be
granted instagram_manage_engagement: an Instagram Login
connection returns a 400 with code instagram_likes_require_facebook_login, and an
account whose token predates the permission returns a 403 with code
reconnect_required. Instagram also enforces a burst limit of 50 like or unlike
calls per 5 seconds per Instagram account, and exceeding it locks that account out
of the like API for an hour, so pace bulk loops.

Like or upvote a comment on a post. Supported platforms: Facebook, X, Bluesky, Reddit, LinkedIn, and Instagram in limited release (see below). For Bluesky, the cid (content identifier) is required in the request body. For LinkedIn, pass the composite comment URN returned by the comments endpoints as commentId; an optional reactionType picks the reaction (defaults to LIKE), and accounts connected before the social-feed scopes were requested get a 403 with code `linkedin_reconnect_required`. Instagram is in LIMITED RELEASE and not generally available: the call needs `instagram_manage_engagement`, which Meta has so far granted this app only under Standard Access, so it works for app admins, developers and testers of our Meta app and returns a 403 with code `PLATFORM_BETA_RESTRICTED` for every other account. That restriction lifts when Meta App Review grants Advanced Access; the constraints below apply once it does. Instagram covers comments and replies on feed posts, reels and carousels. Only an account connected through Facebook Login can be granted `instagram_manage_engagement`: an Instagram Login connection returns a 400 with code `instagram_likes_require_facebook_login`, and an account whose token predates the permission returns a 403 with code `reconnect_required`. Content from private accounts cannot be liked. Instagram also enforces a burst limit of 50 like or unlike calls per 5 seconds per Instagram account, and exceeding it locks that account out of the like API for an hour, so pace bulk loops.
Pin comment
Pin a top-level comment to the top of a post's comment section. TikTok accounts connected through the TikTok for Business app only; every other platform returns 400.
