Hi @RoronoaHemesh, the popular endpoint doesn't support the "sort_by" option, it is sorted by popularity.desc by default. That is the whole purpose of the endpoint.

So, can you please tell me what can I do for sorting? I have a page where the popular movies are rendered and displayed, and I want to implement the sorting method like the one on the website.

If you read the doc for the popular endpoint previously referenced, there is a note at the top that explains how it is really a discover call, you can use discover to make changes to sorting and other options.
