Inserting row into custom module dynamically in code

I built a custom module that handles some data I am retrieving from a 3rd party through an API. I am now building a custom task that will be run nightly through Kentico's scheduled tasks and am looking to rewrite all the data in the custom module. I'm not sure if I am just missing it in the documentation, but is there a way to insert data into a custom module through c# code?
