CloudAPI confirmed, and I'll use Meta's official Cloud API exclusively. The trickiest part of this integration isn't sending messages, it's reliably handling incoming webhooks. Meta's webhook verification requires a specific GET/POST flow, and if your server doesn't respond with a 200 within a few seconds, messages get dropped silently. I'll set up a queue-based approach so webhook payloads are stored immediately and processed async, keeping nothing lost even under bulk volume. For your admin panel, I'll build the two-way chat interface with per-user conversation history, template message support, media handling, and bulk messaging. Message status callbacks (sent, delivered, read) will update in real time via Meta's status webhooks. All messages, incoming and outgoing, get stored in MySQL with proper indexing for search.

Hi, I understand your recruitment platform's existing infrastructure, including the live Flutter mobile app and PHP-based Admin Panel. To integrate WhatsApp fully with your admin panel, I'll follow a structured approach. Firstly, I'll set up the Official Meta WhatsApp Business Cloud API, configuring webhook endpoints to receive incoming WhatsApp messages in the admin panel. This will enable real-time two-way communication between WhatsApp and your platform. To ensure seamless communication, I'll implement a module that allows admin users to reply directly from the admin panel, displaying the complete chat history for each user. This will streamline your recruitment process and improve user engagement. To maintain consistency, I'll work closely with your team to design and implement a secure and scalable WhatsApp template messaging system. This will enable you to send approved template messages to users, enhancing your communication strategy. During the project, I'll maintain regular communication with your team, providing updates on progress and addressing any concerns. My goal is to ensure a smooth integration process, minimizing disruptions to your existing infrastructure. Before starting, I have a few questions to clarify the project scope: - What is the expected volume of WhatsApp messages, and how often will they be sent? - Are there any specific security or compliance requirements for the WhatsApp integration? Once these details are confirmed, I'll begin working on the project, delivering regular updates and ensuring timely completion. Best Regards, Anil Prajapati
