How to simulate series of actions in rest api?

How can i simulate a series of actions that user do in simple CRUD REST API? I'm implemented a simple blog CRUD REST API(Nodejs with nestJs) and i want to test it. I'm want to simulate 100 new posts and then read it, and then maybe delete 20 posts and then again adding another 30 posts.

Is there any tool that can help me do it? I know that jest is a tool to unitesting but unitest isn't the case here.
