To use Exotel APIs, you need to authenticate with your **API Key**, **API Token**, and **Account SID**. These credentials, along with the correct subdomain, are required for all API requests.

## Where to Find Your Credentials

- Log in to your Exotel account.
- Go to the **API Settings** page.
- Copy your **API Key**, **API Token**, and **Account SID**.

## Example

```bash
curl -u <your_api_key>:<your_api_token> \
    https://<subdomain>/v1/Accounts/<your_sid>/Calls/connect
```
