Whatsapp, Openai, and Bitrix24 Integration

Project Overview: WhatsApp Cloud API Integration with n8n, OpenAI, and Bitrix24
Objective:
The goal of this project is to create an automated workflow using n8n, integrating WhatsApp Cloud API, OpenAI (ChatGPT), and Bitrix24 CRM to streamline customer interactions, automate responses, and store conversation history efficiently.

Key Components of the Workflow:
WhatsApp Cloud API (Meta):

Handles incoming and outgoing messages via a registered WhatsApp Business phone number.
The webhook receives messages from customers and triggers the n8n workflow.
Sends automated responses to customer inquiries using AI-generated text.
N8n Workflow Automation:

Acts as the central hub for orchestrating message flow between WhatsApp, OpenAI, and Bitrix24.
Listens for incoming messages via a Webhook Node from WhatsApp Cloud API.
Processes the request and forwards it to OpenAI for response generation.
Sends responses back to the customer via WhatsApp.
Logs the conversation in Bitrix24 CRM for future reference.
OpenAI (ChatGPT Integration):

Processes incoming WhatsApp messages and generates AI-powered responses.
Provides intelligent, contextual responses based on customer inquiries.
Bitrix24 CRM Integration:

Stores conversation history for each customer.
Updates existing records or creates new contacts in Bitrix24.
Tracks customer interactions for sales and support teams.
