Compare platforms
One feature, every platform, side by side.
How each platform connects and what it publishes. Each platform page documents its own post types and fields.

Not supported: Google Business Profile, WhatsApp, iMessage, Telegram, Discord, Slack
- LinkedIn saves: personal accounts only.
- LinkedIn clicks: organization accounts only.
- LinkedIn views: video posts only.
- YouTube shares come from the daily Analytics API, not the basic Data API.
Google deprecated per-post analytics with no replacement. Use the Performance API for location-level metrics (impressions, clicks, calls, directions, bookings).
Dedicated endpoints go further on 3 platforms: YouTube audience demographics (age, gender, country), Google Business Profile daily performance metrics and search keywords, and the Instagram account, follower and Story endpoints listed on the Instagram page.
The Inbox API serves DMs, comments and reviews from every platform through Messages, Comments and Reviews.
Discord sends outbound DMs from the bot through POST /v1/discord/dms; replies do not arrive, so it is not part of the inbox. See the Discord page.
Like comment covers Facebook, X, Bluesky, Reddit, LinkedIn and TikTok. On LinkedIn it takes the composite comment URN as commentId and an optional reactionType. On Instagram it is in limited release: it needs Meta's instagram_manage_engagement permission, which Zernio holds under Standard Access, so it works for admins, developers and testers of Zernio's Meta app and returns a 403 with code PLATFORM_BETA_RESTRICTED for every other account, and only on accounts connected through Facebook Login (Instagram comments).
Comment automations answer a keyword comment with a private-reply DM (and an optional public reply) on Instagram and Facebook, and with a public reply only on TikTok, Threads, LinkedIn and YouTube, which have no private reply to a comment. TikTok comments arrive by webhook (business accounts only); Threads, LinkedIn and YouTube are read by the comment poll, so the reply follows the comment by up to the poll interval. X accounts are refused with a 400 (platform_not_supported) while X comment polling is off.

A "no" means the platform's API does not expose the event. Slack fires message.received for DMs and mentions (Slack page). reaction.received fires on Instagram, Facebook, WhatsApp, iMessage, Telegram and Slack. The webhooks page has every payload.
