WhatsApp Client Response Automation

I need a compact solution that lets me answer my clients on WhatsApp instantly and consistently. The goal is simple: streamline all client-facing chat so every incoming message receives a prompt, well-structured reply, even when I’m away from the phone.

Here’s what I have in mind:
• Integrate WhatsApp (Business API, Twilio, or another approved gateway) with a lightweight autoresponder or bot that I can customise with greetings, FAQs and follow-up triggers.
• Make the setup easy to tweak—new canned responses, business hours, and escalation to a live agent should be editable without code.
• Provide clear instructions so I can monitor conversations, pull basic chat logs, and hand over chats to a human seamlessly when needed.

Acceptance criteria
• First incoming client message gets an automated reply in under 5 seconds.
• I can add or edit at least five text templates on my own.
• Handover to a live chat window works on both mobile and desktop.
• A short guide (PDF or screencast) shows me how to maintain the system.

If you have prior experience integrating WhatsApp for client communication—especially with small business setups—let’s make this happen quickly.
