API Fundamentals and OpenAI Basics
Introduction to Postman and OpenAI API: Setting Up the Environment3:52
In this lesson, we will dive into the basics of using Postman as a tool to test APIs from OpenAI. We will explore how to configure the Postman environment, create workspaces and collections, and integrate the OpenAI API into our project. Starting with signing in to Postman, we will create a new workspace and collection, and then proceed to the OpenAI API playground to generate an API key. We will learn how to store the API key as a variable in Postman, set up authorization using the key, and configure the environment for seamless integration with OpenAI tools. Join us to discover the initial steps to leverage Postman and OpenAI for your projects. See you in the next lesson!
Building a Chatbot with OpenAI APIs: Model Integration and Rule7:11
In this lesson, we will continue our journey of building a chatbot using OpenAI APIs. After setting up our workspace and collection in Postman and adding the API key to the environment, we will start by fetching data from the OpenAI documentation. Navigating to the models section, we will explore the various models provided by OpenAI, with a focus on GPT-3.5 Turbo, the model we will utilize for our chatbot. We will extract the endpoint for GPT-3.5 Turbo and return to Postman to construct our API request by specifying the endpoint.
However, during our initial request, we will encounter an authorization error, reminding us to include the API key in the authorization section. We'll rectify this by adding the key to the authorization headers. Once the authorization is set, we'll encounter another error, indicating the requirement for model parameters. It's now time to start building our chatbot.

Building a Simple Chatbot Web Page with OpenAI API Integration4:07
In this lesson, we will take the next step in our chatbot development journey by building a simple web page that utilizes the OpenAI API. After successfully testing the API using Postman, we will now proceed to construct a web page with the help of ChatGPT. We'll provide ChatGPT with the necessary instructions and parameters, such as the HTML code and JSON configuration, including the endpoint URL and API key.

Deploying Your AI Chatbot on a Real Website with Custom UI5:35
In this lesson, we move from building the chatbot logic to actually deploying it as a real, styled web application that can be shared and used online. You will learn how to connect your chatbot to a ready-made front-end using three core files: HTML for structure and text, CSS for design and layout, and JavaScript for logic and API integration.

We will customize the welcome message and input hints, define the system role of the chatbot, add a loading (“thinking”) message, and securely connect the bot to the OpenAI API using your API key. Finally, you will see how changing the CSS instantly affects the look and feel of the chatbot, giving you full control over branding and user experience.

By the end of this lecture, you will have a fully functional, styled chatbot running in the browser, ready to be embedded in any website or shared with real users.
Configuring and Deploying Your Custom Chatbot: Uploading to Live Servers7:21
In this lesson, we will dive into the process of configuring and utilizing a chatbot template to create our own personalized chatbot. The template consists of HTML, JavaScript, and CSS files, and we'll focus on configuring the HTML and JavaScript components.
Starting with the HTML code, we'll open it using a text editor and explore the existing messages, such as the welcoming message and thinking message. We'll modify the welcoming message to suit our desired greeting and save the file. Returning to the chatbot template, we'll observe the updated welcoming message. However, without setting up the API key, the chatbot will display a thinking message without generating a response.
