Security
- Bot tokens are stored securely in Publora
- Bot tokens are never exposed in API responses
- Use the Publora dashboard to manage bot credentials — do not hardcode tokens in your application
Tips for Telegram
- Bot must be admin — without admin rights, all posts fail
- Caption limit is stricter — 1,024 chars for media captions vs text-only messages
- Markdown formatting works — use bold, italic, code blocks, hyperlinks for rich messages
- WebP auto-converted to JPEG
- Private channels use numeric ID; public channels use
@channelname - Scheduling works — use
