Phase 1 Plan 1: Telegram Echo Bot Summary
n8n workflow with Telegram trigger, user ID authentication via environment variable, and echo response with timestamp
Performance
- Duration: 5 min
- Started: 2026-01-28
- Completed: 2026-01-28
- Tasks: 2 (1 human-action, 1 auto)
- Files modified: 1
Accomplishments
- Telegram bot created and configured in n8n (user action)
- n8n workflow JSON created with 4 nodes: Trigger, IF, Code, Send
- User authentication via $env.TELEGRAM_USER_ID environment variable
- Silent ignore for unauthorized users (no false branch nodes)
- Echo response includes original text and ISO timestamp
Task Commits
Each task was committed atomically:
- Task 1: Create Telegram Bot and Configure n8n - (human action, no commit)
- Task 2: Create n8n Workflow for Telegram Echo -
9d503bb (feat)
Files Created/Modified
n8n-workflow.json - Complete n8n workflow definition for import
Decisions Made
- Used environment variable ($env.TELEGRAM_USER_ID) for auth - keeps sensitive data out of workflow JSON
- HTML parse mode enabled for future formatting (bold, italic, links)
- Silent ignore (empty false branch) for unauthorized users - no information leak
Deviations from Plan
None - plan executed exactly as written.
Issues Encountered
None - workflow JSON created and validated successfully.
User Setup Required
User completed setup during Task 1:
- Created Telegram bot via @BotFather
- Configured TELEGRAM_BOT_TOKEN and TELEGRAM_USER_ID as n8n container environment variables
- Created Telegram API credential in n8n
Next Phase Readiness
- Workflow JSON ready for import into n8n
- User must import workflow and activate it to test echo functionality
- Foundation ready for Docker integration (Phase 2)
Phase: 01-foundation
Completed: 2026-01-28
