Backend & AI Integration

This project uses a powerful backend workflow orchestrated by n8n, integrating Google's AI and communication services.

Architecture

1. n8n Workflow: The core logic is handled by an n8n workflow (configuration available in n8n_config.json).
2. Google Gemini: We utilize the Gemini Pro model (via Google AI Studio) to generate high-quality, context-aware marketing copy and HTML email templates in multiple languages.
3. Google Workspace (Gmail): The generated emails are automatically sent to the recipient using the Gmail API.

Setup

To deploy the backend:

1. n8n: Import n8n_config.json into your n8n instance.
2. Credentials:
   • Google Gemini API: Obtain an API key from Google AI Studio and configure the googlePalmApi credential in n8n.
   • Gmail OAuth2: Set up a project in Google Cloud Console, enable the Gmail API, and create OAuth2 credentials. Configure the gmailOAuth2 credential in n8n.
3. Webhook: Ensure the n8n Webhook node URL matches the GENERATE_AND_SEND_URL in the frontend code.
