Nested json of all projects, tasks, subtasks, and fields for each task

Hello! I'm trying to create an overview for all projects, their status, and the status of their tasks, using python -- creating a json file from the below structure

The structure would look something like this:

|____active_projects
____|____prj1
________|____title
________|____custom_field1
________|____custome_field2
________|____start_date
________|____ship_date
________|____status
________|____tasks
____________|____task1
____________|____task2
________________|____title
________________|____status
________________|____due_date
________________|____assignee
________________|____comments
____________________|____comment1
____________________|____comment2
________________________|____author
________________________|____time_posted
________________________|____content
____________________|____comment3
____________|____task3
____|____prj2
____|____prj3
...

the plan is to scrape this information and create an "executive view" for people who want to just go view basic information on each project quickly, without having to go between pages/projects in wrike. this page would be read-only.

I could really use some help getting started on the basics of just getting a project started and viewing project data - how to view projects in python terminal, in what cases would I need to use oauth, and what to be aware of from a security point of view?

thank you in advance for the help!
