Platform accounts and format support
Understand how platform accounts and format support works in Slash Social.
Each connected social profile belongs to one brand. Each draft targets one or more profiles with formats those networks support. Understanding accounts, platforms, and formats explains why Create offers some combinations and blocks others.
Overview
An account is a connected profile: handle, token health, timezone, and active status, scoped to a brand. A platform is the network type (Instagram, TikTok, X, and the rest). One brand can hold multiple accounts across platforms. Organization plan limits cap how many profiles you may connect in total and per platform.
Self-serve plans support nine platforms: Instagram, TikTok, X, Facebook Pages, LinkedIn, YouTube, Threads, Pinterest, and Bluesky. Free includes the same set except X; Starter and above include all nine. See Platform support for the current support matrix.
A format is the post shape: static image, carousel, reel or short video, story, thread, pin, and similar variants. Formats are not universal. The Create flow and validators only offer combinations each selected platform accepts.
How it works
Connection health is checked before publish. Expired or disconnected accounts block scheduling until someone reconnects from Settings connected accounts (the account management modal) or from App Home setup prompts. OAuth reconnect flows open a connection modal and store the new token against the same brand-scoped account row.
Multi-platform posts use one content item with several platform targets. Each target tracks its own account, format, caption overrides, and publish status. Validation runs per target, so one network can be ready while another shows a format or media error.
Platform-specific rules cover caption length, media requirements, mutually exclusive attachments (polls versus links), and scheduling constraints. Some story formats cannot schedule on every network. Errors appear during create, review, or publish with platform-named messages.
Short-form vertical video is treated as equivalent across labels such as reel, short, and video when checking cross-post compatibility, so the same clip can target Instagram and YouTube without picking incompatible names.
Current platform format support:
| Platform | Supported formats |
|---|---|
| Image, carousel, short video; feed, story, and reel placements | |
| TikTok | Short-form video |
| X | Text, image, and link posts; thread placement |
| Facebook Pages | Text, image, carousel, and link posts; feed and story placements |
| Text, image, and link posts | |
| YouTube | Shorts and long-form video |
| Threads | Text, image, and carousel posts; thread placement |
| Image and carousel pins | |
| Bluesky | Text, image, and link posts; thread placement |
Publishing operations (queue, schedule, and recovery) run per platform target after approval. A failure on one target does not automatically roll back siblings on other networks.
Examples
A brand connects @acme on Instagram and LinkedIn. A creator builds one draft, selects both accounts, and picks image format for Instagram and link format for LinkedIn. Each target validates independently before scheduling.
An account token expires over a weekend. Monday’s queued post for that profile fails health checks. An admin opens connected accounts, reconnects via OAuth, and retries from the plan or failed-jobs surfaces.
A creator tries to schedule an Instagram story and a LinkedIn text post in one item. Story scheduling rules differ by platform; validation may pass for one target and block the other until formats align.
