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.

Common errors:

• Error 1363026 — video over 40 min → trim to under 45 min
• Error 1363023 — file over 2 GB → compress
• Error 1363128 — Reels duration outside 3–90s range

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

    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; connect them individually in Publora dashboard
• Video limits: 45 min / 2 GB via API (native allows 240 min / 4 GB)
• Reels: Must be 3–90 seconds; limited to 30 per day per Page
• Carousels: Up to 10 images or videos (cannot mix in the same carousel)
• Rate limit formula: 200 × users/hour
