## Introduction

📝 In this tutorial, you will learn how to integrate CronWeb with RapidAPI using Python and the Requests library. CronWeb enables you to schedule and run cron jobs easily, while RapidAPI provides a vast collection of APIs for various purposes. By combining the two, you can automate tasks and access external APIs on a scheduled basis. 🚀

## Prerequisites

Before we begin, make sure you have the following:

1. Python installed on your machine (preferably Python 3.x) 🐍
2. The Requests library installed (`pip install requests`) 📦
3. A RapidAPI account (sign up at [RapidAPI](https://www.rapidapi.com/)) 🌐

---

## Section 1: Creating a RapidAPI Account and Obtaining an API Key

To access RapidAPI services, you need an API key. Follow these steps to get your API key:

1. Sign up or log in to your RapidAPI account at [RapidAPI](https://www.rapidapi.com/). ✅
2. Go to [CronWeb](https://rapidapi.com/joshirajesh448-emyeudCJ4Y-/api/cronweb-webhook-driven-cron-job-scheduler) tool and Subscribe to [FREE Plan(Basic)](https://rapidapi.com/joshirajesh448-emyeudCJ4Y-/api/cronweb-webhook-driven-cron-job-scheduler/pricing). 🔄
3. Once subscribed, you will receive an API key. Keep it safe, as we'll use it in our Python script. 🔑

## Section 2: Implementing the CronJob with RapidAPI Integration

Now, let's create a Python script that uses CronWeb API to schedule a task to make a webhook request to our server on specified date and time. Here's an example:

```python
import requests
import os

RAPIDAPI_KEY = os.getenv('RAPIDAPI_KEY')

def schedule_job():

    url = "https://cronweb-webhook-driven-cron-job-scheduler.p.rapidapi.com/schedule/"

    payload = {
        "description": "Send email to inactive users",
        "url": "https://api.example.com/your-webhook-endpoint", # replace with your webhook server
        "method": "POST",
        "params": {},
        "payload": {    # payload as per your requirements
            "action": "inactive.email",
            "message": "Send e-mail to inactive users on upcoming monday morning"
        },
        "headers": {    # optional headers
            "signature": "X-example-Signature": "xxxxxxxxxxxxxxxxxxxxxxxxxx"
        },
        "minute": 0,
        "hour": 7,
        "day": 17,
        "month": 8,
        "timezone": "UTC"
    }
    headers = {
        "content-type": "application/json",
        'X-RapidAPI-Key': RAPIDAPI_KEY,
        "X-RapidAPI-Host": "cronweb-webhook-driven-cron-job-scheduler.p.rapidapi.com"
    }

    response = requests.post(url, json=payload, headers=headers)

    print(response.json())  # save the returned "id" to access the task later

if __name__=="__main__":
    schedule_job()

```

In the above code snippet:

- We import the necessary modules: requests for making HTTP requests, and os for accessing environment variables. 📦
- We define the `schedule_job` function that makes an HTTP GET request to the desired RapidAPI endpoint, passing the necessary headers with the API key from the environment variables. ⚙️
- We print the JSON response. 🖨️

## Section 3: Running the Python Script

To run the Python script, follow these steps:

1. Create a new file named script.py. 📁
2. Copy and paste the code snippet from Section 2 into script.py. 📋
3. Replace 'https://api.example.com/your-webhook-endpoint' with the actual webhook endpoint URL you want to call. 🌐
4. Save the changes. 💾
5. You can start the script by running the command python script.py in your terminal. 🚀
6. Now, make sure the specified `url` is accessible through the internet with provided headers and HTTP method. CronWeb will make API request to the server at the date and time you specified. 📅
