Publora — Instagram

Instagram 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: instagram-{accountId}

Requirements

• Instagram Business account recommended — personal accounts are not supported; Creator accounts may also work (instagram_business_* scopes), but Business is the officially tested and recommended type
• Connected directly via Instagram OAuth through the Publora dashboard (no Facebook Page required)

Platform Limits (API)

⚠️ Instagram API is significantly more restrictive than the native app.

First 125 characters visible before "more".

Common errors: - (#10) The user is not an Instagram Business — Creator accounts not supported, switch to Business - Error 2207010 — caption exceeds 2,200 chars - Error 2207004 — image exceeds 8 MB - Error 9, Subcode 2207042 — rate limit reached

Post an Image

// Step 1: Create the 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: 'Your caption here ✨ #hashtag',
    platforms: ['instagram-17841412345678'],
    scheduledTime: '2026-03-20T12:00:00.000Z'
  })
}).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',   // ⚠️ JPEG only for Instagram
    type: 'image'
  })
}).then(r => r.json());

// Step 3: Upload to S3
await fetch(upload.uploadUrl, {
  method: 'PUT',
  headers: { 'Content-Type': 'image/jpeg' },
  body: imageFileBytes
});

Post a Carousel (up to 10 images)

Call get-upload-url N times with the same postGroupId:

import requests

HEADERS = { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' }

# Create post
post = requests.post('https://api.publora.com/api/v1/create-post', headers=HEADERS, json={
    'content': 'Swipe through our product highlights! 👆',
    'platforms': ['instagram-17841412345678'],
    'scheduledTime': '2026-03-20T12:00:00.000Z'
}).json()

# Upload each image (max 10)
images = ['slide1.jpg', 'slide2.jpg', 'slide3.jpg']
for img_path in images:
    upload = requests.post('https://api.publora.com/api/v1/get-upload-url', headers=HEADERS, json={
        'postGroupId': post['postGroupId'],
        'fileName': img_path,
        'contentType': 'image/jpeg',
        'type': 'image'
    }).json()
    with open(img_path, 'rb') as f:
        requests.put(upload['uploadUrl'], headers={'Content-Type': 'image/jpeg'}, data=f)

Post a Reel (video, up to 3 min via API)

// Create post, then upload video via get-upload-url with type: 'video'
const post = await createPost({
  content: 'Check out our latest Reel! 🎬',
  platforms: ['instagram-17841412345678'],
  platformSettings: { instagram: { videoType: 'REELS' } }
});

const upload = await getUploadUrl({
  postGroupId: post.postGroupId,
  fileName: 'reel.mp4',
  contentType: 'video/mp4',
  type: 'video'
});
// Then PUT the video file to upload.uploadUrl

⚠️ Reels via API accept up to 3 minutes (180s) / 300 MB. Native app allows 20 min — API is significantly stricter. Only videos 5–90 seconds appear in the Reels feed tab; longer clips post but show as regular video posts.

Platform Quirks

• JPEG recommended: The Instagram Graph API works best with JPEG. PNG may work in practice but is not guaranteed. Always use JPEG to be safe — Publora does NOT auto-convert for Instagram.
• Business account recommended: Personal accounts are not supported. Creator accounts may work via instagram_business_* scopes but are not fully tested — Business is safest.
• Reels via API: The platform-limits doc (March 2026) states 3 min (180s) max; the platform-specific doc states 15 min. Use 3 min as the safe design limit. Only videos 5–90s appear in the Reels tab regardless.
• Stories vs Reels: Use platformSettings: { instagram: { videoType: "STORIES" } } to post as Story (disappears after 24h). Default is "REELS".
• No shopping tags, branded content, filters, or music via API
• Carousels: 2–10 items (native allows 20); cannot mix images and videos in same carousel
• WebP: Must be converted to JPEG manually before upload
• Aspect ratios: Instagram supports 4:5 (portrait) to 1.91:1 (landscape); images outside range will be cropped
• Hashtags: Max 30 per post; included in caption text (no separate field)
