Publora — Facebook

Facebook platform skill for the Publora API. For auth, core scheduling, media upload, and workspace/webhook docs, see the publora core skill.

Base URL: https://api.publora.com/api/v1
Header: x-publora-key: sk_YOUR_KEY
Platform ID format: facebook-{pageId}

If you manage multiple Pages, each Page gets its own platform ID.

Requirements

• A Facebook Page (not a personal profile) connected via OAuth
• Page admin permissions granted during OAuth

Platform Limits (API)

⚠️ API video limits are significantly stricter than native.

Property	API Limit	Notes
Text (API)	Up to 63,206 characters	Publora frontend editor caps at 2,200; API itself has no lower limit
Images	Up to 10 × 10 MB	JPEG, PNG, GIF, BMP, TIFF; WebP auto-converted to JPEG
Video	45 min / 512 MB (Publora server limit)	FB natively allows 2 GB — Publora caps at 512 MB
Reels duration	3–90 seconds	Pages only; 30/day
Reels rate limit	30 Reels/day/Page	—
Reels posting	Pages only (not profiles)	—
Text only	✅ Yes	—

Token management: Facebook page tokens expire after 59 days. Publora auto-refreshes, but if refresh fails silently (permission changes), posts will fail without a clear token error — reconnect the page in dashboard.

Common errors:

• Error 1363026 — video over 45 min → trim
• Error 1363023 — file over 2 GB (Publora's 512 MB limit kicks in first)
• Error 1363128 — Reels duration outside 3–90s range

Posts under 80 characters get 66% more engagement on Facebook.

Post a Text Update

await fetch('https://api.publora.com/api/v1/create-post', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' },
  body: JSON.stringify({
    content: 'Exciting news from our team! We just launched a new feature. Check it out at publora.com 🎉',
    platforms: ['facebook-123456789']
  })
});

Schedule a Post

body: JSON.stringify({
  content: 'Your Facebook Page update',
  platforms: ['facebook-123456789'],
  scheduledTime: '2026-03-20T13:00:00.000Z'
})

Post with Image

// Step 1: Create post
const post = await fetch('https://api.publora.com/api/v1/create-post', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' },
  body: JSON.stringify({
    content: 'Check out our latest product photo!',
    platforms: ['facebook-123456789']
  })
}).then(r => r.json());

// Step 2: Get upload URL
const upload = await fetch('https://api.publora.com/api/v1/get-upload-url', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' },
  body: JSON.stringify({
    postGroupId: post.postGroupId,
    fileName: 'photo.jpg',
    contentType: 'image/jpeg',
    type: 'image'
  })
}).then(r => r.json());

// Step 3: Upload
await fetch(upload.uploadUrl, {
  method: 'PUT',
  headers: { 'Content-Type': 'image/jpeg' },
  body: imageBytes
});

Post a Reel (3–90 seconds)

Use the same flow but upload a short video file. Reels are posted to Pages only.

Platform Quirks

• Pages only — personal profiles are not supported via the Facebook Graph API
• Multiple pages — each Page has a separate platform ID; include multiple facebook-{pageId} in platforms array to post to several at once
• Video limit: 45 min / 512 MB (Publora server cap — FB natively allows 2 GB; Publora's limit kicks in first)
• Reels: Must be 3–90 seconds; Pages only; 30/day per Page
• Images only in multi-media: Multiple videos in one post are not supported — they'll go through the photo path incorrectly. Use one video per post.
• No mixed media: Images + video in same post will fail at Facebook API level (Publora doesn't pre-validate this for Facebook)
• WebP auto-converted to JPEG — no action needed
• 59-day token: Publora auto-refreshes page tokens; reconnect dashboard if you see unexplained posting failures
• Link previews: Including a URL in text triggers Facebook's auto link preview — not controllable via API
• Rate limit formula: 200 × users/hour
