This is especially useful for generating disposable email addresses for privacy-conscious users or for testing purposes.\n\n#### Workflow Details:\n1. **Webhook Trigger**: The workflow is initiated by sending a POST request to a specific webhook. You can include `state` and `description` in your request body to customize the masked email's state and description.\n2. **Session Retrieval**: The workflow makes an HTTP request to the Fastmail API to retrieve session information. It uses this data to authenticate further requests.\n3. **Create Masked Email**: Using the retrieved session data, the workflow sends a POST request to Fastmail's JMAP API to create a masked email. It uses the provided state and description from the webhook payload.\n4. **Prepare Output**: Once the masked email is successfully created, the workflow extracts the email address and attaches the description for further processing.\n5. **Respond to Webhook**: Finally, the workflow responds to the original POST request with the newly created masked email and its description.\n\n#### Requirements:\n- **Fastmail API Access**: You will need valid API credentials for Fastmail configured with HTTP Header Authentication.\n- **Authorization Setup**: Optionally set up authorization if your webhook is exposed to the internet to prevent misuse.\n- **Custom Webhook Request**: Use a tool like `curl` or create a shortcut on macOS/iOS to send the POST request to the webhook with the necessary JSON payload, like so:\n  \n  ```bash\n  curl -X POST -H 'Content-Type: application/json' {{ $env.WEBHOOK_URL }} -d '{\"state\": \"pending\", \"description\": \"my mega fancy masked email\"}'\n  ```\n\nThis template simplifies the process of integrating masked email functionality into your projects or workflows and can be extended for various use cases."
