This n8n workflow automates the entire process of handling makeup booking requests through a webhook, calculating prices dynamically based on selected services, and generating invoices via Xendit. It initiates with a webhook trigger when a booking form is submitted, processes booking details to assign unique IDs and format contact information, and calculates the price considering makeup type, add-ons, and service location. The workflow also generates a payment invoice with Xendit, sends a personalized WhatsApp message with booking details and payment link using GoWhatsApp API, and manages chat presence states to simulate typing for a more engaging customer experience. This automation streamlines booking management, enhances customer communication, and simplifies payment collection for makeup services, making it suitable for salons or makeup artists managing appointments online.
