Supported Networks and Their Capabilities

Overview

StretchSocial maintains a platform registry describing eleven supported networks and exactly what each one can and can't do. This article is your reference for choosing targets, understanding character limits, and knowing which networks need a business account or app review before they can go live.

Networks you can target in the composer

Seven networks appear as target buttons in Compose, each with a character limit the composer is aware of:

Because X caps captions at 280 characters while LinkedIn allows 3,000, a single caption that reads well on LinkedIn may be too long for X. Write to the shortest network you're targeting, or maintain a tighter variant for short-form channels.

The full registry

Beyond the seven composer networks, the registry also covers Pinterest, Google Business Profile, Snapchat, and Bluesky — eleven networks in total. For each network the registry records a rich set of capability flags:

• Posting supported — whether the network accepts published posts. (Snapchat is currently not marked posting-supported.)
• Media upload and video — whether images and video are supported. (Google Business Profile and Threads are marked no-video.)
• Reels / Shorts — supported on Instagram, TikTok, and YouTube.
• Analytics — whether the network exposes performance data (most do; Bluesky does not).
• Comment management and DMs — supported on a subset (for example, Facebook and YouTube for comments).
• Requires business account — Facebook, Instagram, LinkedIn, Pinterest, and Google Business Profile.
• Requires app review — most networks require platform app review before live posting; Bluesky does not.
• OAuth support and required scopes — the specific permissions each network needs (for example, Instagram needs instagram_content_publish and instagram_basic).
• Account type required — for example, an Instagram Business or Creator account connected to Meta assets, or a verified Google Business Profile location.

Adapter status and live readiness

Every network in the registry currently shows dry-run enabled and live disabled, with an adapter status of planned (Snapchat is noted as partial/unmounted). This reflects governed publishing: you can plan, approve, and schedule for any supported network today, and live delivery is switched on per network by your administrator once its OAuth, token storage, and app-review requirements are met. See Understanding governed publishing for how activation works.

Concrete example

You're planning a video campaign and want short-form video on the right networks:

1. You check the registry and confirm Reels/Shorts is supported on Instagram, TikTok, and YouTube.
2. You avoid Google Business Profile and Threads for this piece because they're marked no-video.
3. You note Instagram requires a Business or Creator account, so you make sure your Instagram connection uses one.
4. You compose one post, target Instagram, TikTok, and YouTube, and let each become its own queue job.

Tips

• Match your content type to the network's capabilities — don't target a no-video network with a video piece.
• Networks that require a business account (Facebook, Instagram, LinkedIn, Pinterest, Google Business Profile) need the right account type on their connection.
• Always verify current provider limits before a network goes live — the registry notes remind administrators to confirm rate limits and review requirements per platform.

FAQ

Which networks can I actually pick when composing? LinkedIn, Facebook, Instagram, X, Threads, TikTok, and YouTube. Pinterest, Google Business Profile, Snapchat, and Bluesky are in the registry for planning and future activation.

Why can't I post to Snapchat? It's currently not marked posting-supported in the registry; its API scope is pending review.

Do character limits get enforced? The composer is aware of each network's limit and warns you; keep captions within the shortest targeted network's limit for safety.
