ExpertProfessionalCRM AutomationScheduled trigger13 nodes

Remind upcoming appointments: Telegram

Runs on a schedule across Telegram, Google Sheets and PostgreSQL, walks the list in batches, pausing between them, then rolls the rows up into a few numbers. Built for contact sync, around a "Read Pending Queue (PostgreSQL)" step, in 13 documented nodes.

Remind upcoming appointments with PostgreSQL and Telegram. An original, ready-to-import n8n workflow built around the 'Reminders & Follow-ups' pattern for sales & CRM. It runs on a schedule and orchestrates 13 nodes across Telegram, Google Sheets, HTTP / REST API. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. The result is a hands-off process that just works.

Key benefits

  • Keeps Telegram and Google Sheets in step for contact sync, without anyone re-typing a row
  • A failed Telegram or Google Sheets call is retried rather than dropped, at any of the 13 nodes in this contact-sync build
  • The pause before Telegram is durable — a contact-sync run survives a restart
  • Batches the work so Telegram rate limits never break a contact-sync run
  • Fans the same result out to PostgreSQL in the same run, for contact sync

Use cases

  • Teams keeping Telegram and Google Sheets aligned by hand for contact sync
  • Contact sync sequences that run over days and must survive a restart before Telegram
  • A backlog too large to push into Telegram in one pass, across 13 nodes
  • Contact sync work where "Read Pending Queue (PostgreSQL)" is still a manual step before Telegram

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Core level

A compact production shape: validation and error handling without extra machinery.

  • Scheduling time-based follow-ups that survive restarts
  • Exiting the sequence when the task is already done
  • Moving data between PostgreSQL, Google Sheets and Telegram in a single run

Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.

Common questions

What exactly do I get?

The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.

How do I import it into n8n?

In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.

Do I need anything else for it to work?

You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Telegram, Google Sheets, HTTP / REST API, PostgreSQL). No coding is required.

What if it doesn't work for me?

If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.

Can I modify or resell it?

You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
