Hello,

We are building an AI-powered legal assistant called Jurisplus IA Cameroon, currently hosted on ChatGPT:

We would like to integrate this assistant into WhatsApp so users can interact with it directly via WhatsApp Business.

Here is what we need clarification on:

Can we connect our own OpenAI API key?
Can your system handle conversation memory/context?
What are your setup costs and monthly fees?
What is the per-message pricing for Cameroon-based usage?
How long does WhatsApp Business API verification take?
Can we scale to 5,000–10,000 active users?
What backend hosting requirements are needed?
Do you support webhook integrations with a custom backend?
Our goal is to replicate the behavior of the GPT assistant linked above, but via WhatsApp.

Please also clarify onboarding timeline and technical documentation.

Thank you.
