Use case
Automate recurring data sync between apps
Keep Airtable, Google Sheets, Notion, your Postgres database and your product APIs in sync without keeping a worker alive. Crontap triggers a Zapier zap, Make scenario, n8n workflow or your own sync endpoint on a schedule, and tells you when something breaks.

The problem
Why this is painful without the right tool
- Airtable, Sheets and Notion don't have real built-in schedulers. The "sync every X" automations cap out at hourly on free tiers.
- Writing a small Lambda or cron job for a 5-minute sync is overkill; you spend more time wiring logs than syncing data.
- When Zapier's own scheduled trigger runs slowly or silently fails, you find out from an angry customer instead of a log.
- Multi-app syncs (say Stripe → Postgres → Airtable) need multiple steps triggered in sequence at predictable times.
The fix
How Crontap solves it
Crontap acts as the scheduler you'd otherwise have to build yourself. Point a schedule at your sync endpoint (a Zapier catch hook, a Make webhook, an n8n trigger or a function on your own API) and pick the cadence. Crontap calls it with the right headers and payload, retries on failure, and pings your team when something goes wrong.
*/5 * * * *A typical data-sync flow looks like this: Crontap hits your sync webhook on a schedule, your endpoint pulls from the source (Airtable, Stripe, a third-party API), transforms, and writes to the destination (Sheets, Notion, Postgres). If anything 5xx's or times out, Crontap retries and pushes a failure alert to Slack or email so you know within minutes, not hours.
Two concrete walkthroughs we've written: Crontap + Make + Airtable and Crontap + Zapier + Airtable.
FAQ
Common questions
- Can Crontap run every 5 minutes? Zapier's scheduler caps me at hourly.
- Yes. On the Pro plan, Crontap schedules go down to 1 minute. You point Crontap at the Zapier webhook URL and let it drive the cadence, so you get Zapier's 7,000+ integrations with sub-hour scheduling.
- What if my sync endpoint takes 30 seconds to run?
- No problem, long-running sync endpoints are common. Crontap waits for the response up to its per-request timeout, logs status code and duration, and moves on. If your next scheduled run fires before the previous finishes, that's fine: runs don't stack on top of each other.
- How do I get notified if a sync fails?
- Every schedule has an Integrations panel where you can add Slack, Discord, Telegram, email or any custom webhook for failure (and optionally success) events. Failures include the status code and response body so you can debug without opening the dashboard.
