    # Inbound API


    The Inbound API allows you to manage email infrastructure programmatically -
    domains, email addresses, webhooks, and more.


    ## Authentication


    All API requests require a Bearer token in the Authorization header:


    ```bash

    curl -H "Authorization: Bearer YOUR_API_KEY" \
      https://inbound.new/api/e2/domains
    ```


    ## Base URL


    ```

    https://inbound.new/api/e2

    ```


    ## Quick Start


    1. **Create a domain** - Register your domain with Inbound

    2. **Configure DNS** - Add the provided DNS records to your domain

    3. **Create an email address** - Set up addresses to receive emails

    4. **Create an endpoint** - Configure where emails are delivered (webhook,
    forwarding, etc.)
