# Introduction

> Schedule recurring webhooks and one-time delayed jobs with a simple REST API

CronAPI lets you schedule HTTP webhook calls on a recurring cron schedule or as one-time delayed jobs. Manage everything through the REST API or the web dashboard.

## Key features

* **Cron scheduling** — Define recurring webhooks using standard cron expressions
* **One-time jobs** — Schedule a single webhook call for a specific future time
* **Custom requests** — Configure HTTP method, headers, and JSON body for each webhook
* **Execution tracking** — View run history with status codes, response times, and errors
* **API-first** — Full REST API with Bearer token authentication
