Events API doesn't seem to giving out result for section changes

Hi,

I need to track all the status/section changes in a project for each task. Due to requirements constraints I cannot go to webhooks. So I tried events api. But that doesn’t seem to give out such result (mostly empty result), I moved some tasks in board and tried with both project_id and task_id. Is there any way I can track that changes? Or Am I doing something wrong here?

Attached a screenshot of API Explorer for reference.

Hope this is not something plan specific.

Thank you
