WhatsApp Support Chat Integration

I’m looking to set up a dedicated WhatsApp admin chat focused on customer support. The goal is to let visitors message us from our website and have every conversation flow into a single, manageable dashboard.

Key needs
• Customer support orientation – incoming messages should be easy to assign, track, and resolve.
• Chat history and logs – every interaction must be stored so agents can reference previous conversations and export transcripts when required.
• Website integration – I want a clean “Chat on WhatsApp” entry point on our site that opens the correct thread and passes along basic context (page URL, visitor name if captured).

Preferred approach
If you have experience with the WhatsApp Business API, Cloud API, or providers like Twilio, please outline how you would:
1. Configure the number, templates, and webhook endpoints.
2. Build or connect an agent dashboard (even if you leverage existing tools such as Freshchat, Zendesk, or a custom Node/PHP panel).
3. Store message history in a secure, query-friendly database.
4. Embed a lightweight website widget that triggers the WhatsApp chat on both desktop and mobile.

Deliverables
• Functional WhatsApp customer-support channel with live website entry point.
• Dashboard or panel showing active chats and full logs.
• Basic admin documentation covering setup steps and how to retrieve past conversations.

I’m open to suggestions on tech stack as long as the end result is reliable and compliant with WhatsApp’s policies. If you’ve completed similar WhatsApp integrations, please share links or brief descriptions so I can assess fit quickly.
