Phase 03 Plan 02: Callback Query Handling Summary

Inline button infrastructure with did-you-mean suggestions using HTTP Request for Telegram API and stateless callback_data encoding

Performance

• Duration: 15 min
• Started: 2026-01-30T13:27:00Z
• Completed: 2026-01-30T13:42:00Z
• Tasks: 3
• Files modified: 1

Accomplishments

• Telegram Trigger now receives both message and callback_query updates
• Route Update Type switch separates message vs callback flows
• IF Callback Authenticated validates user before processing callbacks
• Find Closest Match scores containers and suggests best match for typos
• Build Suggestion Keyboard creates inline_keyboard JSON with short callback_data
• Send Suggestion uses HTTP Request to Telegram API (workaround for native node limitation)
• Full callback flow: Parse -> Route -> Handle (Cancel/Expired/Execute)
• Cancel: answer query "Cancelled", delete suggestion message
• Expired: answer query with alert, delete message
• Execute: run Docker action, answer query, delete message, send result

Task Commits

Each task was committed atomically:

1. Task 1: Configure Telegram Trigger for callback queries - 2cbf6e7 (feat)
2. Task 2: Implement suggestion flow for no-match cases - 56eea26 (feat)
3. Task 3: Handle suggestion callback and execute action - 768d758 (feat)

Files Created/Modified

• n8n-workflow.json - Extended from 27 to 41 nodes with callback infrastructure:
  • Route Update Type, IF Callback Authenticated (Task 1)
  • Find Closest Match, Check Suggestion, Build Suggestion Keyboard, Send Suggestion (Task 2)
  • Parse Callback Data, Route Callback, Handle Cancel/Expired, Build/Execute/Parse Callback Action, Answer/Delete/Send result (Task 3)

Decisions Made

• Use HTTP Request node for sendMessage with inline_keyboard - native Telegram node has expression bug with dynamic keyboards
• Encode action as single character (s=start, t=stop, r=restart, x=cancel) to fit callback_data 64-byte limit
• Require minimum score of 2 for suggestions - prevents suggesting unrelated containers
• 2-minute timeout enforced via timestamp in callback_data (stateless approach)
• Delete suggestion message after any button click for clean chat UI

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Single-container suggestion flow complete
• Multiple-match batch confirmation still uses placeholder text (could be enhanced in future)
• Ready for Phase 04: Logs & Intelligence
• Container update flow (pull + recreate) deferred to later plan
