Chat with OpenAI through WhatsApp

I would like to setup an environment that allow my user to chat with a standard OpenAI Model (gpt-3.5-turbo) using WhatsApp as interface.

I would like you to use the No-Code integration platform Make.com handling messages between the WhatsApp user and the OpenAI modelo.

I will provide the WhatsApp API layer (Z-api.io) and the WhatApp number for that.

In Summary the job is to put together the pieces with the following information flow:

User --> WhatsApp Message --> Z-api.io webhook --> Make.com --> OpenAI Model

OpenAI Model Responde --> Make.com --> Z-api Send Text --> WhatsApp --> User

The conversation must mantain a historical context, so is also necessary to retain the conversation in a database.

I would like to use a PostgreeSQL DB based on the Serverless PostgreSQL service called Bit.io. All data writing and retrieving will be made using NoCode components at Make.com.

Tools to be used:
OpenAI (Chat API) : https://platform.openai.com/docs/api-reference/chat
Bit.io (Serverless Postgree): https://bit.io/
Make.com (Integration Platform): https://www.make.com/en
Z-API (WhatsApp API): https://www.z-api.io/

Please provide quote, schedule and the considerations you feel are necessary.

Please do not ask for detailed scope, provide quote with a set of assumptions making the assumptions clear in your quote.

All the best,
Michel
