This video tutorial explains how to write code for an API endpoint that returns tweets belonging to a specific user. It involves copying an existing function, modifying it to include a user ID parameter, and implementing a filter to fetch tweets by user ID. The tutorial also covers error handling to manage cases where no tweets are found, ensuring a 404 status is returned with an empty response. The video concludes with a brief summary of the steps covered.
