What it is

Crontap: the homepage
Crontap is a scheduler for recurring API calls and webhooks to any HTTP endpoint. You can describe schedules in plain English like "every 15 minutes" or use classic cron expressions, with support for per-schedule IANA timezones. The platform includes automatic retries with exponential backoff, detailed run history and logs, uptime monitoring from 1 minute to 24 hours, and heartbeat checks that alert on silence. Notifications route to Slack, Discord, Telegram, or email, with integrations for Zapier, Make, n8n, and generic webhooks. An AI integration can summarize or extract data from run responses. The platform includes an MCP server for managing schedules from AI editors.

Quick answers
Does Crontap fix WordPress wp-cron missing scheduled tasks?
Yes. wp-cron is pseudo-cron that only fires when a visitor loads the site, causing low-traffic sites to silently miss tasks. You disable wp-cron in wp-config.php and let Crontap hit wp-cron.php on a real external schedule at any cadence in your store's business timezone.
Can I get notified when a scheduled call fails?
Yes. Crontap retries server errors, timeouts, and connection failures with exponential backoff, then alerts connected Slack, Discord, Telegram, or email channels if retries are exhausted. Failure alerts include status code, duration and error summary.
Do I need to know cron syntax to use Crontap?
No. Crontap includes templates for common patterns and a plain-English scheduler, so you can describe schedules like "every 15 minutes" or "every weekday at 09:30" without writing cron expressions. A free cron debugger is available at tool.crontap.com/cronjob-debugger if you prefer cron syntax.
What happens if a scheduled call takes longer than expected?
Crontap enforces a sensible timeout per request. If a call exceeds the timeout, the run is marked as failed and configured failure integrations fire.
What's the shortest interval Crontap supports?
Every 1 minute on paid plans. That beats Vercel Cron Hobby (hourly minimum) and matches Google Cloud Scheduler (1 minute) without the per-target IAM dance Cloud Scheduler requires. GitHub Actions cron sits at a 5 minute minimum and can drift 15 minutes during peak per their own docs.
