Publora Facebook

Post or schedule content to Facebook Pages using the Publora API. Use this skill when the user wants to publish or schedule Facebook posts via Publora.

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

javascript

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

javascript

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

Post with Image

javascript

// 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
