[Notice] Full Renewal Guide: Transitioning from OAuth to API Key Method
Hello, students.
As Anthropic officially discontinued the OAuth method for both business and individual users as of April 4th, our course has also been completely renewed from OAuth to the API Key method.
Not much has changed significantly, and the major changes are as follows.
The permission handling part has been changed to the API Key method.
Features related to plan usage do not exist in the API Key, so they have been deleted.
All 55 source codes for the entire course have been updated to the API Key standard, so you can download and use them as they are.
You don't need to worry just because it changed from OAuth to an API Key. The core of this course is building an agent from scratch, and that essence hasn't changed at all.
If you build it from scratch, you will be able to see the entire flow of the agent. In fact, many people have recently provided feedback saying they were "surprised that the structure and concepts are identical to Claude Code." As such, more than 90% of the concepts covered in this lecture are the same as Claude Code, and once you understand these concepts, you will be fully capable of developing agents using MCP or the Agent SDK.
Please do not be discouraged and continue to study hard as you have been doing. Thank you!
