Creating and Updating Tables via HTTP Request Outside Clay UI

Hello, Wanted to know if there is there a way to create a table and add rows via HTTP Request outside of the Clay UI ? And if so is there more concrete documentation on that? This is the only link I found regarding that https://docs.clay.com/en/articles/9672489-http-api-with-clay Is there any ability to create tables? Can we send a post update to said table and how do we target that table?
