Platforms

OmniSocials supports 12 channels across 11 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, in the platforms and urls fields of post.published events

The ID you pass in the accounts array on a post is NOT a channel ID. It is an account_id you get from GET /accounts. Each account is tied to a specific channel.

Connecting accounts

All account connections happen through OAuth in the OmniSocials dashboard (Settings → Channels), not through the API. Once connected, accounts are available to every API key in the workspace. The dashboard handles token refresh, re-authorization prompts, and revocation.

• Facebook
