It sends a confirmation email to the customer and a detailed notification to a Slack channel.\n\n## Key Feature\nThe core logic of this flow is **new customer detection and reward**. It checks if it's the customer's first purchase and, if so, creates and sends a 10% discount coupon for their next order, dynamically including it in the messages.\n\n## Setup (Quick Checklist)\n1.  **`Configs` Node**: Start here. Define your main variables (company name, site, webhook validation token).\n2.  **HTTP Request Nodes**: Insert your Abacate Pay API keys in the `GetOrders` and `CreateCustomCoupon` nodes.\n3.  **Credentials**: Connect your accounts in the `Send Email` and `Slack` nodes and select the correct recipients."
