I want to put an end to manual “Thanks, we got your order” messages. My goal is a small yet reliable WhatsApp Business automation that detects any incoming order-confirmation message and fires back an instant, personalised acknowledgement that covers receipt, next-steps and contact details. I’m happy for you to build on the official WhatsApp Business Cloud API, Twilio or another stable, policy-compliant platform. What matters is that customers receive the reply within a few seconds and that I can tweak the text or add variables later without touching code. Deliverables • Live connection to my existing WhatsApp number with the auto-response in place • Simple way for me to edit message content (web form, config file or similar) • Step-by-step setup notes including token renewal and template approval Acceptance criteria: under-3-second response time in a 50-message test, 99 % success rate and no account flagging. I’ll supply account credentials and the exact wording once we start, and I’m open to whichever trigger logic—keywords, templates, even a light NLP layer—you feel gives the most reliable result.
