Platform Limits (API — Bot API)

| Text (message) | 4,096 characters | Same |
| Media caption | 1,024 characters ⚠️ | 4,096 (Premium) |
| Images | Up to 10 × 10 MB | JPEG, PNG, GIF, WebP, BMP |
| Video | 50 MB ⚠️ | 4 GB |
| Video formats | MP4, MOV, AVI, MKV, WebM | — |
| Text only | ✅ Yes | — |
| Rate limit | 30 messages/sec | 20 messages/min per group |
Common errors:
MEDIA_CAPTION_TOO_LONG— caption exceeds 1,024 chars → reduce or move text to message bodyBad Request: file is too big— file exceeds 50 MB → compress or use a smaller file

method: 'POST',
headers: { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' },
body: JSON.stringify({
content: '📢 **Announcement**: Our new feature is live! Check it out at publora.com\
\
#update #publora',
platforms: ['telegram--1001234567890'] // note: group chat IDs are negative

Schedule a Message
body: JSON.stringify({
content: 'Your Telegram channel message here',
platforms: ['telegram--1001234567890'],
scheduledTime: '2026-03-20T09:00:00.000Z'
})Send an Image
import requests
HEADERS = { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' }
# Step 1: Create post (content = caption, max 1,024 chars for media)
post = requests.post('https://api.publora.com/api/v1/create-post', headers=HEADERS, json={
'content': 'Check out our latest update! 🚀', # keep under 1,024 chars when attaching media
'platforms': ['telegram--1001234567890']
}).json()
# Step 2: Get upload URL (max 10 MB per image)
upload = requests.post('https://api.publora.com/api/v1/get-upload-url', headers=HEADERS, json={
'postGroupId': post['postGroupId'],
'fileName': 'image.jpg',
'contentType': 'image/jpeg',
'type': 'image'
}).json()
# Step 3: Upload
with open('image.jpg', 'rb') as f:
requests.put(upload['uploadUrl'], headers={'Content-Type': 'image/jpeg'}, data=f)Send a Video (max 50 MB)
Same flow as image but use contentType: 'video/mp4' and type: 'video'. Keep the file under 50 MB.
Platform Quirks
- Bot API file limit is 50 MB — not 4 GB like Telegram user clients. For larger files, you'd need a Local Bot API Server (not supported by Publora)
- Caption vs message body: When attaching media,
contentbecomes the caption (max 1,024 chars). For text-only posts, content can be up to 4,096 chars. - Markdown supported: Use
**bold**,_italic_, `,link` in message content - Group chat IDs are negative: e.g.
telegram--1001234567890 - Bot must be admin: The bot needs admin permissions to post in channels; in groups, it needs at least "Send messages" permission
- Rate limit: 30 messages/second globally; 20 messages/minute per group — Publora handles queuing automatically
