Custom WA sender with AI replies, image support, pacing, admin

Description

Timeline: 5-10 daysYou are developing a custom WhatsApp automation application, hosted on my own server, to replace the current WAChatbot-ACWBot system. The app must:• Send automated WhatsApp messages triggered by ActiveCampaign tags, without using Twilio or WAChatbot or paid apps.• Integrate with my OpenAI Assistant ("Charlie") to:o Automatically respond to user messages based on conversation history.o Attach and send images intelligently when relevant.• Provide an admin panel to create, manage, monitor, and cancel campaign messages.• Ensure message pacing (only when triggered by ActiveCampaign) between 1m10s and 2m10s, randomly spaced.• Be scalable to support multiple WhatsApp numbers (1-5 accounts), each with its own queue and assistant.
