Hello, I can integrate and manage WhatsApp API for your system so you can send and receive messages, handle customer inquiries, and automate workflows directly within your platform. The integration will support secure authentication, message templates, notifications, and two-way communication, all aligned with WhatsApp Business API policies. I’ll also provide an admin view to manage conversations, track usage, and ensure smooth scaling as your message volume grows. Questions: – Do you already have a WhatsApp Business API provider (e.g., Meta Cloud API, Twilio, 360dialog), or should I set that up for you? – Should the integration include advanced features like chatbots and auto-responses, or focus only on message sending/receiving? – Would you like chat history to be stored in your database for reporting and analytics? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran.

Hello, I’m an experienced developer with a strong background in WhatsApp Business API integration and automation.

@ahmedmubshar1

Hi, Do you want each client’s WhatsApp Business API account isolated under its own verified setup, or should I build a centralized multi-tenant system where you can manage campaigns across brands from a single dashboard? That choice will shape scalability and long-term management. I’ve worked on WhatsApp Business API integrations where account creation, template management, webhooks, and customer database connections had to be secure and compliant. For your project I’d build a robust Node.js/Python backend on AWS, integrate it with your existing CRM for personalized campaigns, and set up automated flows for welcome messages, updates, and support. Ongoing maintenance, troubleshooting, and detailed documentation would ensure uptime and reliability. This won’t just be an integration it will be the foundation of a scalable service you can offer clients with confidence. The kind of infrastructure that builds trust and drives long-term growth. Ahmed
