Description
This Telegram workflow batches rapid-fire messages from the same user into one prompt (20β30s debounce), then sends a single AI reply.
It uses two Google Sheets:
- Message Retention (
date | user_id | message) β queues incoming messages. - Message Checkup (
user_id | is_waiting | last_updated) β debounces per user.
Flow per message:
- Log to Message Retention.
- Read Message Checkup for that
user_id. If empty, synthesize{ is_waiting:false }. - IF (OR):
last_updatedis older than 30s, oris_waitingis false
β Start wait window: setis_waiting=true, updatelast_updated, Wait (e.g., 30s).
- After Wait: fetch all queued messages for the user, merge them, delete those rows, send one AI answer to Telegram, then clear the Waiting row.
- If a new message arrives while waiting, we only refresh
last_updated(extend the window) β we do not start another wait.
Copy/paste:
- Older-than-30s:
{{ new Date(Date.now() - 30000).toISOString() }} - βNo Rowsβ normalizer (Code node) ensures the IF always has data to check.
Supports text and voice (voice via Whisper). Works reliably on Telegram once the webhook is registered and Sheets are shared with the service account.
