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 → trimError 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}inplatformsarray 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
