Advanced WhatsApp Sales Automation System Development

Job ID: 40175654

Budget: $10 – $30 USD

Custom WhatsApp Automation System: Hotmart Integration, AI Agent & Multi-API Contingency

Context: Currently, I use ManyChat for sales automation via Hotmart, but the platform frequently experiences instability. I'm looking for a developer to create a proprietary, scalable, and robust system using n8n as the main orchestrator.

The Challenge: I need a solution that connects Hotmart webhooks to multiple official WhatsApp APIs (Cloud API, Twilio, 360dialog, etc.) to ensure contingency. If one provider fails, the system should automatically switch to the next.

Technical Requirements and Functionalities:

Orchestration via n8n: Centralize the sending and receiving logic.

Hotmart Integration: Process events such as:

Purchase Approved

Boleto/Pix Generated

Abandoned Cart

Card Declined

API Contingency (Failover): Support for 2 or 3 official API providers.

AI Agent (OpenAI/Anthropic):

The system sends a template (HSM) to open a 24-hour window.

If the user responds, the AI ​​takes over the conversation to answer access questions, provide support, and overcome objections (focus on conversion).

Analytics Dashboard (Essential):

Delivery, read, and response rates by provider.

Conversion tracking (recovered sales).

Real-time API health status.

What I'm looking for: A professional with experience in WhatsApp APIs, LLM (AI) integration, and databases for the dashboard. Please detail which technology stack you suggest for the dashboard and how you would structure the switching between APIs.
