Use case
Schedule social media posts via webhook
Drip posts to Twitter/X, LinkedIn, Bluesky, Mastodon and beyond on your own cadence. Crontap triggers IFTTT, Zapier, Make or a custom webhook on a cron, so your drafts queue lands on time and you hear about it when something fails.

The problem
Why this is painful without the right tool
- Most social schedulers lock your queue into their UI; you can't drive it from your own content pipeline or CMS.
- Free plans on Buffer, Hootsuite and friends throttle how many posts you can queue or the earliest time slots.
- Custom cadences ("three posts a day, two hours apart, weekdays only") don't map cleanly to dropdowns.
- When a post silently fails to publish, you discover it days later when engagement looks weird.
The fix
How Crontap solves it
Crontap gives you a schedule with a real cron expression pointed at any publishing webhook. Use IFTTT or Zapier for the social side, build your own Bluesky/Mastodon posting endpoint, or combine both. Every run is logged with status and response; failures trigger a Slack or email alert.
0 9,13,17 * * 1-5The typical flow: your content engine (a CMS, a Sheet, a database) exposes an endpoint that returns “the next thing to post” and pushes it to the social API of your choice. Crontap calls that endpoint on a cron. You decide the tempo in a cron expression, not a dropdown, so “weekdays only”, “on even hours” or “every other Tuesday” are all one line.
A worked example of the IFTTT side (for posting to X/Twitter) is in our Crontap + IFTTT guide.
FAQ
Common questions
- Can Crontap post to Twitter/X directly?
- Not directly. X's API is restricted and paid, so the clean setup is to have Crontap trigger an IFTTT applet or a Zapier zap that has the X posting action, and pass the post body in the payload. For Bluesky or Mastodon, which have open APIs, Crontap can post directly: set the Authorization header and the payload, done.
- How do I stagger posts across multiple accounts?
- Create one schedule per account. Each schedule gets its own cron expression, timezone and payload, so you can shift timing per account without copy-pasting config. If you want a single source of truth, have one endpoint that takes an `account` field in the payload and routes to the right provider.
- What if a post fails to publish?
- Crontap logs status code and response body. Add a failure notification in the Integrations panel for Slack, Discord or email so you get pinged within minutes. For frequent posters, set a Slack alert that only fires after two consecutive failures to avoid noise.
