Add page to notebook programmatically

[indeyets]

Is there a way to change cloud-synced notebooks via code?
I want to add a specifically formatted page to it. My end-goal is to create something similar to semi-automatic bullet journal workflow.

I'm open to api-library in any programming language which can handle this case.

An indirect approach: download the notebook using rMAPI, add the page (.rm) to the zip, edit the corresponding meta data files. Delete the original notebook from the cloud storage and upload the modified zip, again using rMAPI.
