Take your ChatGPT practice into web application development by learning how to work with the OpenAI API. You'll start with OpenAI concepts and personal account creation and management, then explore the Chat API and the steps involved in sending a request and parsing a response. You'll build your first web application with ChatGPT, examine function calling, and apply the GPT best practices covered in the course. You'll also review the API testing guidance included alongside these development activities. From there, you'll explore hosting a web application at home, including local hosting fundamentals and port forwarding configuration. As you move from account setup to requests, application development, and hosting, you'll connect the API concepts with practical ways to develop custom ChatGPT solutions. Module quizzes will help you check your understanding of the OpenAI foundations, API features, and hosting concepts you encounter.
