# Getting Started

CallHub API lets you get notifications from CallHub campaigns as webhooks. You can also add new contacts, start or stop campaigns and more.

## API Endpoint

API endpoint is <https://api-[region].callhub.io/v1/> Response format is JSON. All APIs are served over HTTPS only. Some examples on how to request the data:

```curl
curl -H 'Authorization: Token {api_key}' -H "Content-Type: application/json" -X 
GET https://api-[region].callhub.io/v1/users/
```
```python
# You'll need to install requests
import requests
headers={'Authorization':'Token %s' % api_key,
         'Content-Type':'application/json'}
r = requests.get('https://api.callhub.io/v1/users/',
                headers=headers)
users = r.json()
```
