I am putting together an in-house outreach stack and need the full source code for a WhatsApp marketing application. The build must let me broadcast messages in bulk—text, images, video, and link attachments—while keeping my contacts organised with tagging, import/export and basic CRM-style notes. Automated replies triggered by keywords or templates are required so leads get an instant response even when I am offline. A reporting layer is equally important. I want to see delivery status per message, read receipts where the API allows it, click statistics for any links sent and overall campaign summaries that I can export. I am flexible on language and framework; PHP, Node, Python, or Java are all acceptable as long as you include a clean, well-commented codebase and an install guide that takes me from fresh server to first campaign in clear steps. Deliverables • Complete, unencrypted source code • Database schema / migrations (if used) • Installation & environment setup guide • Short README explaining how to trigger broadcasts, set auto-replies, manage contacts and view analytics The project will be considered done when I can deploy the code on my own VPS, send a small test broadcast, receive automated replies, and view the metrics dashboard without errors.
