I have been running all my WhatsApp engagement through Interakt, but I’m ready to move everything onto my own infrastructure. I’m considering the CodeCanyon script “WhatsCRM – Chatbot, Flow Builder, API Access” ( https://codecanyon.net/item/whatscrm-chatbot-flow-builder-api-access-whatsapp-crm-saas-system/51122205 ) and I’m equally open to a solid open-source alternative that delivers the same depth of control. What I need is straightforward: install the chosen platform on my server, connect it to the official WhatsApp Cloud API, migrate my current contacts and opt-ins from Interakt, and make sure the flow builder, chatbot module, and public API endpoints all work flawlessly. The end product should let me create broadcast or automated flows without touching the code each time, pull message analytics through the API, and scale to multiple numbers if I decide to add them later. Deliverables • Clean deployment on my VPS, secured with SSL and best-practice hardening • Verified WhatsApp Cloud API connection and phone number setup • Migration of existing subscribers (CSV export from Interakt is ready) • Working flow builder with at least one sample automation live • Chatbot responding to keywords and fallback to live agent hand-off • API documentation or Postman collection showing common calls (send, read, list contacts) Acceptance criteria • I can log in and run a test broadcast to my own number without errors • Incoming messages appear in the inbox within two seconds on average • No console or server log errors for 48 hours after go-live If you have already deployed a similar WhatsApp CRM—whether the exact CodeCanyon package or another self-hosted stack—let’s get this rolling quickly.
