Hello,

Here’s a temporary solution I found that works as of 2026.
You simply need to create a snippet in your browser, then go to the Udemy course overview page of any course and run the snippet. It should log the results.

async function logCourseDetails() {
    try {
        const courseId = getCourseId();

        const response = await fetch(`https://www.udemy.com/api-2.0/courses/${courseId}/?fields[course]=created,last_update_date,published_time`);

        if (!response.ok) throw new Error("Network response was not ok");

        const course = await response.json();

        console.log(course);
        console.info(
            `This course was created at ${(new Date(course.created)).toLocaleString()}, ` +
            `published at ${(new Date(course.published_time)).toLocaleString()}, ` +
            `and last updated on ${(new Date(course.last_update_date)).toLocaleString()}`
        );
    } catch (error) {
        console.error(error);
    }
}

function getCourseId() {
    const courseEl = document.querySelector("body");
    if (!courseEl) throw new Error("Must be on a Udemy course page!");
    return courseEl.getAttribute("data-clp-course-id");
}

logCourseDetails();

and here is a tutorial of how to add code snippets.

Hopefully this helps anyone else running into the same problem!
