Which Platforms Does UniLink Social Planner Support? (Full List + Connection Guide)

UniLink Social Planner connects to Instagram, TikTok, Facebook, Twitter/X, LinkedIn, Pinterest, YouTube Community, and Google Business — here's exactly what you can publish to each one.

Before you can schedule content, you need to know what UniLink can actually publish — and what it can't. Each social platform has its own API rules, account type requirements, and content restrictions. This article covers every supported platform, what post types work on each, the key technical limits you need to know, and exactly how to connect each account so you can start scheduling without running into unexpected errors.

What Platform Support Means in UniLink Social Planner

UniLink connects to social platforms through their official developer APIs. This means your posts are published as native content — they appear in feeds exactly as if you had posted manually from the platform's own app, with full access to likes, comments, shares, and algorithmic reach. There are no watermarks, no "posted via third party" labels on feed posts, and no link previews in place of real media.

Some platform features require specific account types. Instagram Stories scheduling, for example, only works with Business or Creator accounts connected via the Instagram Graph API. Personal Instagram accounts do not expose the Stories endpoint to third-party tools — this is an Instagram restriction, not a UniLink limitation. The same logic applies to Facebook Groups (you need admin permissions) and LinkedIn Company Pages (you need admin or editor role). The sections below spell out exactly what account type each platform requires.

Connection is done once per account via OAuth — you authorize UniLink to post on your behalf, and the connection stays active until you revoke it or the platform token expires. Tokens on most platforms last 60 days and are refreshed automatically as long as you stay active. If a token expires, UniLink will notify you and prompt you to reconnect.

How to Get Started With Connecting Platforms

1. Open Connected Accounts — In your UniLink dashboard, go to Settings → Social Planner → Connected Accounts (or click "Connect Account" directly from the Social Planner screen).
2. Choose a platform — Click the logo of the platform you want to connect. A list of all supported platforms is shown on the connections page.
3. Complete OAuth authorization — You will be redirected to the platform's login page. Log in with the account you want to connect and click "Authorize" or "Allow." You are then redirected back to UniLink.
4. Select the right account type — For platforms like Facebook and LinkedIn, you will be shown a list of Pages, Groups, or Company Pages associated with your login. Select which one you want to connect to UniLink.
5. Confirm the connection — The platform appears in your Connected Accounts list with a green status indicator. You can now select it when composing posts.
6. Repeat for additional accounts — You can connect multiple accounts per platform (e.g., two different Instagram accounts). Each appears as a separate selectable target in the post composer.
7. Test the connection — Create a post, select only the newly connected platform, and schedule it for two minutes in the future to verify publishing works before scheduling real content.

How to Get the Most Out of Multi-Platform Publishing

Not every platform deserves the same content. The biggest win you get from a multi-platform scheduler is not just saving time — it's having one place where you can consciously decide which platforms get which types of content. Use the platform checkboxes in the composer as a content strategy decision, not just a broadcast switch.

Think about format first. A 90-second talking-head video belongs on TikTok and Instagram Reels. A written thought leadership piece belongs on LinkedIn and maybe Twitter/X. A product photo styled for lifestyle belongs on Instagram Feed and Pinterest. Google Business posts belong when you have a promotion, event, or operational update. Routing the right format to the right platform is where most of the engagement improvement comes from.

Connect all your accounts even if you do not use all of them every week. Having a platform connected costs nothing and means you can quickly add it to a post if a piece of content happens to be a good fit. Disconnecting and reconnecting repeatedly is more friction than just leaving accounts connected.

Monitor the Connected Accounts page once a month. Platform API tokens do expire, and some platforms (Facebook especially) revoke tokens when you change your password or update security settings. A quick monthly check of your connection health prevents failed posts from catching you off guard.
