Connect your first social account

This guide walks you through connecting your first social account in PostFast and publishing a post.

1. Open the Accounts page

In the sidebar, open Accounts. This is where every connected social account lives.

2. Click Add Social Account

Click the Add Social Account tile, then pick the platform you want to connect. PostFast supports 11 platforms today:

• Facebook
• Instagram
• TikTok
• YouTube
• LinkedIn
• X (Twitter)
• Pinterest
• Threads
• Bluesky
• Google Business Profile
• Telegram

3. Sign in and grant permissions

Each platform opens its own authorization screen. Follow the prompts and approve access.

4. Confirm the connection

After authorizing, you're returned to the Accounts page. The new account appears as a card in the grid with its avatar, handle, and platform badge. That's "connected."

If an account doesn't appear, refresh the page. If it still isn't there, retry the Add Social Account flow.

5. Send a test post

1. Click New Post at the top of the sidebar. You'll land on the Create post composer.
2. Select the account you just connected from the Post settings panel on the right.
3. Type a caption, and optionally attach an image or video. Upload limits: images ≤ 10 MB, videos ≤ 250 MB. Supported formats: .jpeg, .png, .gif, .webp, .mp4, .webm, .mov, .quicktime.
4. Click Post now to publish immediately, Pick time to schedule, or Save as Draft to save for later.
