WhatsApp Product Info Assistant

I need help building and running a WhatsApp-based assistant that can 1) answer product questions, 2) push offers and promotions, and 3) give basic customer support. I want a hybrid setup: first-line interactions should be automated so buyers get instant replies, yet I also need an easy way to step in manually whenever a conversation gets complex or a sales opportunity appears.

The assistant must converse fluently in English and Indonesian, switching between them as the customer prefers. Please include in your proposal how you would:

• Configure the WhatsApp Business API (or an equivalent approved solution) for both automated flows and human hand-off.
• Create or adapt conversation templates for FAQs, promo broadcasts, and support scenarios.
• Train the bot so it recognizes when to transfer the chat to me or another agent.
• Provide clear instructions or a lightweight dashboard so I can trigger manual messages and review chat history.

Experience with chatbot frameworks such as Dialogflow, ManyChat, Twilio, or similar tools is welcome. Once the system is live, I’d like a short period of monitoring so we can refine replies and ensure the opt-in promo messages comply with WhatsApp policies.

If this scope matches your expertise, let me know your preferred platform and estimated timeline for each milestone so we can get started.
