I need an automated welcome system on my WhatsApp chat. The goal is simple: whenever a new contact writes to me for the very first time, they should instantly receive a personalized greeting without my manual intervention. Here’s what I expect from you: configure or code the auto-responder so it detects that first incoming message and fires the welcome text right away. I’m flexible on the tech—Twilio, WhatsApp Business API, Meta Cloud API, or a lightweight Node/Python script running on my server are all fine as long as the result is reliable and compliant with WhatsApp’s policies. Deliverables • Working auto-response solution connected to my existing WhatsApp number • Clear instructions for updating the welcome text in the future • Brief hand-over document showing how to monitor or adjust the trigger if WhatsApp changes its rules I’ll provide the phone number and any necessary API keys the moment we kick off; you provide the smooth, hands-free greeting my new contacts should see.
