I want to move my promotional outreach from manual blasts to a fully automated WhatsApp drip campaign that keeps my customers engaged. The core of the job is to build and deploy a bulk-sender powered by the official WhatsApp Business API. I currently lean toward Wapikon, but I am open to any stable provider you already master. The system must be able to: • Push both text and image messages in bulk. • Queue, schedule, and stagger sends so Meta’s limits are respected. • Pull delivery and read receipts for basic campaign analytics. • Let me load or import contact lists easily and tag them for future drops. You are free to choose the language or framework—Python, Node.js, PHP, or whatever you can maintain long-term—as long as the final code runs on my Linux VPS and can be handed over without license issues. My primary goal is higher customer engagement, not just one-off sales spikes, so clean opt-in handling and a simple dashboard for campaign configuration would be a plus. I need this ready within a month and would prefer someone in Gurgaon for occasional face-to-face discussions, but I am happy to collaborate remotely if you can walk me through testing and deployment over video. Deliverables: 1. Fully functioning sending engine connected to a verified WhatsApp Business number. 2. Source code, documented setup steps, and an .env or config file for keys. 3. Short hand-over session showing me how to create, schedule, and monitor a campaign. If you have already built similar WhatsApp bulk solutions and can show a live demo or code snippet, I would love to see it when you bid.

Hello, I reviewed your WhatsApp API Bulk Messaging project and it immediately stood out because reliable bulk messaging requires proper API integration, automation, and compliance with WhatsApp policies. Problem: Bulk messaging systems often face issues with template management, webhook handling, message delivery, and campaign tracking, leading to unreliable communication. Solution: I can integrate the official WhatsApp Business API with bulk messaging, template management, delivery tracking, webhook handling, campaign automation, contact management, and CRM integration. My experience includes PHP, Laravel, Node.js, REST APIs, webhooks, and WhatsApp Business API integration. The official WhatsApp Business Platform supports scalable business messaging using approved templates and opt-in recipients. Result: You will receive a secure, scalable, and reliable WhatsApp messaging solution that's easy to manage and extend. A few questions: • Will you be using the official WhatsApp Business Platform or a BSP such as Twilio, 360dialog, or AiSensy? • Do you need one-time bulk campaigns, recurring campaigns, or both? • Should the system include delivery reports, scheduling, and contact segmentation? • Do you need CRM, ERP, or eCommerce integration with the messaging workflow? I can start immediately and provide regular progress updates throughout the project. Thanks

Hi, I can build and deploy a compliant WhatsApp Business API drip campaign system for bulk text/image messaging, scheduling, contact tagging, delivery/read tracking, and campaign monitoring on your Linux VPS.

I’m comfortable with WhatsApp Business API, Python/Node.js/PHP, Linux VPS deployment, API integration, contact list import, tagging, scheduling, drip campaigns, webhook handling, delivery/read receipts, dashboard development, and secure `.env` configuration. Deliverables will include: * WhatsApp API integration * Text and image campaign support * Contact import and tagging * Queue and scheduled sending * Send staggering/rate control * Delivery/read receipt tracking * Basic campaign dashboard * Linux VPS deployment * Source code and setup guide * Config/.env documentation * Handover session I’ll focus on clean opt-in handling, compliant sending, reliable automation, and a maintainable system you can operate long term.

Your project requires more than a simple bulk sender — it needs a reliable campaign engine that respects WhatsApp Business API limits, supports engagement workflows, and remains maintainable long-term on your VPS environment. I can build this as a modular backend service using either Node.js or Python, connected to the official WhatsApp Business API provider you choose (including Wapikon if preferred). The system would include: • Bulk text and media messaging • Queue-based delivery with throttling and staggered sends • Scheduled campaigns and retry handling • Delivery/read receipt tracking for campaign analytics • Contact import, tagging, and segmentation • Simple web dashboard for campaign management • Secure environment-based configuration for deployment on Linux VPS For stability and scalability, I would structure the sending flow using asynchronous queues and worker processes to avoid rate-limit issues and improve delivery consistency. I would also include clean opt-in handling and logging so campaigns remain manageable over time. The handover would include complete source code, deployment documentation, environment configuration examples, and a live walkthrough covering setup, campaign creation, scheduling, and monitoring. Estimated delivery is around 3 to 4 weeks depending on dashboard complexity and provider approval timelines for the WhatsApp Business number.

I've built WhatsApp Business Cloud API integrations before, including webhook handling and delivery status tracking, so the core pieces you're asking for queued/staggered sends respecting Meta's rate limits, read/delivery receipt tracking, and contact tagging are things I've implemented previously, not theoretical. My plan: Python backend (FastAPI) as the sending engine, with a simple queue (Redis or even a lightweight DB backed queue depending on your volume) to handle staggering and scheduling without tripping Meta's limits. I'd wire in webhook listeners for delivery/read receipts so you get real campaign analytics, not just "sent" confirmations. For the dashboard, a lightweight web UI for uploading contact lists, tagging, and configuring/monitoring campaigns nothing over engineered, just functional and maintainable by you afterward. Deployment target: your Linux VPS, documented setup with a clean .env for keys, handed over with no licensing lock in. Quick question: do you already have a Meta Business/WhatsApp Business API account approved, or does provider setup (Wapikon or otherwise) need to happen first? That affects the timeline. Happy to walk through testing and deployment over video call as part of handover.

I'd love to tackle this WhatsApp API Bulk Messaging job. Here's my proposal: Building a reliable backend flow that stays clean under real API, deployment, and error-handling conditions is the real work here. With my experience in Python and FastAPI, I can deliver a scalable, maintainable, and clean backend structure that integrates seamlessly with Twilio and other APIs. My work on Jarvis AI - Personal Automation Assistant showcases my ability to orchestrate complex automated workflows and deploy production-grade cloud services. I'll focus on delivering a clean backend codebase, environment setup instructions, and a well-documented API integration flow. To ensure a smooth deployment, I'll clarify the deployment target, API boundaries, and whether this is a greenfield or existing service. Before I begin, I'd like to confirm the project's foundation: do you already have the API contracts and environment ready, or should I define that structure first?
