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' https://your-n8n-instance/webhook/87f9abd1-2c9b-4d1f-8c7f-2261f4698c3c -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."}, "typeVersion": 1}, {"id": "0c5d6d5a-ad0f-451e-9075-1009c8bf7212", "name": "get fields for creation", "type": "n8n-nodes-base.set", "position": [1000, 300], "parameters": {"options": {}, "assignments": {"assignments": [{"id": "870bb03d-c672-49d6-9652-5a0233b16eb2", "name": "state", "type": "string", "value": "={{ $('Webhook').item.json.body.state ?? \"pending\" }}"}, {"id": "ac9b45a0-885f-48b2-b0ec-e38c79080045", "name": "description", "type": "string", "value": "={{ $('Webhook').item.json.body.description ?? \"Test via N8n\" }}"}]}}, "typeVersion": 3.4}, {"id": "be7ba978-00d7-4fb1-9e1b-e3f83285e6fb", "name": "prepare output", "type": "n8n-nodes-base.set", "position": [1540, 300], "parameters": {"options": {}, "assignments": {"assignments": [{"id": "19a09822-7ae0-4884-9192-c6e5bc3393a8", "name": "email", "type": "string", "value": "={{ $json.methodResponses[0][1].created.maskedEmailId1.email }}"}, {"id": "ae8a1fe4-3010-4db8-aa88-f6074cae3006", "name": "desciption", "type": "string", "value": "={{ $('get fields for creation').item.json.description }}"}]}}, "typeVersion": 3.4}, {"id": "dd014889-81eb-4a94-886e-4fe084c504ff", "name": "Webhook", "type": "n8n-nodes-base.webhook", "position": [540, 300], "webhookId": "87f9abd1-2c9b-4d1f-8c7f-2261f4698c3c", "parameters": {"path": "createMaskedEmail", "options": {}, "httpMethod": "POST", "responseMode": "responseNode"}, "typeVersion": 2}], "pinData": {}, "connections": {"Session": {"main": [[{"node": "get fields for creation", "type": "main", "index": 0}]]}, "Webhook": {"main": [[{"node": "Session", "type": "main", "index": 0}]]}, "prepare output": {"main": [[{"node": "Respond to Webhook", "type": "main", "index": 0}]]}, "get fields for creation": {"main": [[{"node": "create random masked email", "type": "main", "index": 0}]]}, "create random masked email": {"main": [[{"node": "prepare output", "type": "main", "index": 0}]]}}}
