Platforms

14 supported social channels

OmniSocials supports 14 channels across 13 platforms, with two more in development. Every channel has a stable string identifier that you pass in the accounts array (via account IDs) and use as a key on platform-specific options.

LinkedIn appears as two independent channels: linkedin for a personal profile and linkedin_page for a company page. A workspace can have both connected simultaneously.

How channel IDs are used

Channel IDs show up in four places:

1. As keys in per-platform content on the post body: { "content": { "default": "...", "linkedin": "..." } }
2. As keys in per-platform media: { "media_urls": { "default": [...], "instagram": [...] } }
3. As top-level keys for platform options on the post body: { "pinterest": { "board_id": "..." } }
4. In webhook payloads, as data.targets[].platform (one entry per selected platform)

The accounts array on a post takes the account id you get from GET /accounts (for example 368204_instagram), or the bare channel ID (instagram). A workspace has one account per channel, so both point to the same connected account.

Connecting accounts

All account connections happen in the OmniSocials dashboard (Settings → Organisation → Workspaces, then the workspace), not through the API: OAuth for most platforms, for Telegram a pick of the channel or group in the OmniSocials bot, and for Discord Continue with Discord or a pasted webhook URL. Once connected, accounts are available to every API key in the workspace. The dashboard handles token refresh, re-authorization prompts, and revocation.
