I want to build an automated WhatsApp communication system using any fast compatible solution Here is what I need: The system should start from a fixed WhatsApp number (Number A). It will send messages in a fixed format that includes 3–4 specific details (like name, code, or amount). These details should be sent sequentially to a specific company’s WhatsApp bot (e.g., Number B). The company bot will reply with a confirmation message or number, which must be sent back automatically to Number A. The final result (confirmation details) should be saved automatically in an Excel file (or Google Sheet).
