Hello, We are building an AI-powered legal assistant called Jurisplus IA Cameroon, currently hosted on ChatGPT: [login to view URL] 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.

I can help with this, I will integrate your Jurisplus IA assistant into WhatsApp using Meta's Cloud API with your own OpenAI key. The bot will maintain conversation context per user, route messages through webhooks, and replicate your existing GPT assistant behavior. For cost efficiency, I will connect through Meta's Cloud API directly rather than a third-party provider and use Redis for session memory. This keeps per-message costs to just OpenAI token usage plus WhatsApp's standard conversation pricing for Cameroon. Questions: 1) Is your OpenAI key on GPT-4 or GPT-3.5, and do you use a custom system prompt? 2) Do you have a verified Meta Business Manager account already? 3) Where is your backend currently hosted? Ready to start whenever you are. ~ Kamran

I've set up WhatsApp Cloud API integrations with OpenAI-powered bots before, so your Jurisplus setup is straightforward for me. Yes you can connect your own OpenAI key, conversation memory is handled via session storage on the backend, and scaling to 5k-10k users is doable with a proper webhook setup on a cloud server. For Cameroon-based usage the per-message cost depends on WhatsApp's pricing tiers (marketing vs utility conversations) - I'll walk you through the breakdown. Business API verification usually takes 2-5 business days once the business is verified on Meta. I can have a working integration up within a week with docs showing exactly what was configured. - Usama

Hi there, I’ve reviewed your plan to bring the Jurisplus IA Cameroon assistant to WhatsApp so users can interact with the legal AI directly through WhatsApp Business. The key objective will be replicating the behavior of your current GPT assistant while ensuring stable messaging delivery, conversation memory, and scalable backend infrastructure. My approach would be to integrate the WhatsApp Business API through providers such as Twilio or Meta Cloud API, connect it with your OpenAI API key, and implement a backend layer that manages conversation context, user sessions, and webhook routing. This allows the assistant to maintain memory across messages while querying the same knowledge logic used in your existing GPT assistant. The system can also log conversations and support webhook integrations with a custom backend for analytics, moderation, or legal data updates. The architecture will be designed to scale to thousands of users by using queue based processing, lightweight APIs, and secure hosting. I can also guide you through WhatsApp Business verification, provide full setup documentation, and outline message cost structures for your region so the system is ready for production use.

I see you want to integrate your legal AI assistant into WhatsApp Business while keeping features like conversation memory and scaling for thousands of users. From past work helping a client deploy a ChatGPT-based assistant on WhatsApp, you can definitely use your own OpenAI API key through WhatsApp Cloud API. I can build a system that preserves context using session management, so conversations feel continuous. WhatsApp Business API verification usually takes 1–3 weeks depending on your business profile. Setup costs are minimal since WhatsApp Cloud API charges mostly depend on message volume, which varies by country—I'll help you estimate based on Cameroon's rates. For scaling 5,000–10,000 users, a serverless backend or containerized app on cloud hosting (like AWS or Azure) is ideal, with webhook support ready to connect your custom backend. To clarify, do you expect mostly text messages, or will users send files or voice notes? Also, should memory reset after inactivity or be long-term? I can handle everything from API integration, conversation state, hosting, to documentation. Once I get detailed requirements, I can provide a clear onboarding timeline and demo. Ready to start building your WhatsApp AI assistant as soon as you’re set.

Hi there, We will connect your Jurisplus IA assistant to WhatsApp Business using Meta's Cloud API, your own OpenAI key, and a webhook-driven backend that handles conversation memory and scales to your 10,000-user target. To handle that volume without drops, we will put a message queue between the WhatsApp webhook and OpenAI calls so traffic spikes get processed reliably instead of timing out under load. Before we scope the build, does your GPT assistant use a custom system prompt we can extract, or will we need to reverse-engineer its behavior? Also, is Meta Business Manager verified on your end, or should we factor that into the timeline? Let us discuss further via chat. Best regards, STALLYONS Technologies
