About this gig
Still replying to WhatsApp messages one by one? Every unanswered lead is money walking out the door.
I build custom n8n WhatsApp AI agents that reply to customers, qualify leads, and push data to your CRM automatically 24 hours a day, no human involvement needed.
What your agent will do:
- Auto-reply to incoming WhatsApp messages using OpenAI or Claude
- Qualify leads with custom conversation logic and questions
- Push captured data to HubSpot, GoHighLevel, Airtable, Google Sheets, or Notion
- Handle FAQs, product questions, and booking requests
- Escalate to a human via Slack or email when needed
- Run on Evolution API, Meta Cloud API, or Twilio
- Lead Qualification
What you get with every package:
- Working n8n workflow (JSON file, ready to import)
- Clean documentation so you can maintain it yourself
I have deployed WhatsApp AI agents for dental clinics, e-commerce stores, transport companies, and sales teams. These are production systems, not demos.
Message me before ordering. Tell me your use case and I will confirm the right approach.

FAQ
Do I need a WhatsApp Business API account before ordering?
A: Yes, you need access to either the Meta Cloud API, Evolution API, or a provider like Twilio. If you don't have one yet, message me first and I can point you in the right direction before you spend anything.
Will the bot actually understand what customers say, or is it just menu-based?
A: It uses a real AI model (OpenAI, Claude, or DeepSeek depending on your preference), so it understands natural language, handles follow-up questions, and responds in context not a scripted decision tree.
Can it handle multiple languages?
A: Yes. The AI model handles multilingual responses natively. Just tell me which languages your customers use and I will configure the prompts accordingly.
What happens when the AI doesn't know the answer?
A: The workflow detects low-confidence or out-of-scope messages and escalates them to a human via Slack, email, or a flagged entry in your CRM whichever you prefer.
Do I need to host anything myself?
A: Not necessarily. The workflow can run on n8n Cloud (their free tier covers most use cases). If you want self-hosted for cost savings or data privacy, I can deploy on your VPS.
Can this integrate with my existing CRM?
A: I support HubSpot, GoHighLevel, Salesforce, Airtable, Notion, and any CRM with a REST API. Tell me which one you use and I will confirm compatibility before you order.
