Platform Limits (API — Bot API)

⚠️ Telegram Bot API has a strict 50 MB file limit (not the 4 GB that user clients allow).

Property	Bot API Limit	User Client
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 body
Bad Request: file is too big — file exceeds 50 MB → compress or use a smaller file

Post a Text Message

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: '📢 **Announcement**: Our new feature is live! Check it out at publora.com\n\n#update #publora',
    platforms: ['telegram--1001234567890']  // note: group chat IDs are negative
  })
});

Markdown formatting is supported in Telegram messages.

Schedule a Message

javascript

body: JSON.stringify({
  content: 'Your Telegram channel message here',
  platforms: ['telegram--1001234567890'],
  scheduledTime: '2026-03-20T09:00:00.000Z'
})

Send an Image

python

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, content becomes the caption (max 1,024 chars). For text-only posts, content can be up to 4,096 chars.
Markdown supported: Use **bold**, _italic_, `code`, [link](url) 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
