n8n Telegram HTML Message Sender (Safe Escaped Format)

Send Telegram messages safely with n8n—auto-escaped HTML, guaranteed length compliance, and clean formatting.

This n8n Telegram HTML Message Sender workflow builds a Telegram message in safe HTML by escaping dynamic values, formatting labels in bold, and ensuring the output stays within Telegram’s 4096-character limit—then sends it to your chosen chat via the Telegram Bot API.

What this workflow does

• Runs on demand when you manually execute it (test-message mode).
• Accepts key inputs: target Telegram chat ID, message title, a set of field labels + values, an optional link, and per-field length limits.
• Escapes special characters in every field value so user data (product names, AI answers, email addresses, etc.) can’t break the Telegram HTML formatting.
• Formats the message using HTML (bold labels, and an optional hyperlink when provided).
• Truncates safely to stay under Telegram’s 4096-character limit.
• Sends the generated HTML to Telegram with parse mode set to HTML, attribution disabled, and automatic retries enabled.

Use cases

• Preview and validate how dynamic content (including special characters) renders in Telegram before wiring into a production workflow.
• Send formatted status updates to a Telegram chat from n8n while protecting against HTML parse issues.
• Share AI-generated text, user-provided fields, or notification data in a consistent, readable HTML layout.

Technical details
