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, max 90s 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']
});

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 are limited to 90 seconds. Longer videos will be rejected.

Platform Quirks

• JPEG only: The Instagram Graph API rejects PNG and GIF. Convert images to JPEG before uploading. Publora does NOT auto-convert for Instagram.
• Business accounts only: Creator accounts ((#10) error) cannot use the Content Publishing API
• No shopping tags, branded content, filters, or music via API
• Carousels: API max is 10 items (native app allows 20); cannot mix images and videos in same carousel
• WebP: Must be converted to JPEG manually before upload
