Remind upcoming appointments: Google Sheets for calendar sync
Runs on a schedule across Google Sheets, Slack and Google Drive, walks the list in batches, pausing between them, then branches on the check before anything is written. Built for calendar sync, around a "Read Pending Queue (Google Sheets)" step, in 23 documented nodes.
Remind upcoming appointments with Google Drive and Twilio and log the results. An original, ready-to-import n8n workflow built around the 'Reminders & Follow-ups' pattern for healthcare & wellness. It runs on a schedule and orchestrates 23 nodes across Google Sheets, HTTP / REST API, Slack. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Your team sees the right data at the right time.
Key benefits
- ✓Keeps Google Sheets and Slack in step for calendar sync, without anyone re-typing a row
- ✓A failed Google Sheets or Slack call is retried rather than dropped, at any of the 23 nodes in this calendar-sync build
- ✓Bad input stops the run for calendar sync instead of landing in Google Sheets
- ✓The pause before Google Sheets is durable — a calendar-sync run survives a restart
- ✓Batches the work so Google Sheets rate limits never break a calendar-sync run
Use cases
- →Teams keeping Google Sheets and Slack aligned by hand for calendar sync
- →Calendar sync sequences that run over days and must survive a restart before Google Sheets
- →A backlog too large to push into Google Sheets in one pass, across 23 nodes
- →Calendar sync work where "Read Pending Queue (Google Sheets)" is still a manual step before Google Sheets

What's inside (23 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Production levelProduction-grade: idempotency, dead-letter handling, and reconciliation included.
- •Scheduling time-based follow-ups that survive restarts
- •Computing due dates and windows from timestamps
- •Exiting the sequence when the task is already done
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 (Google Sheets, HTTP / REST API, Slack, Google Drive, …). 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.
