Create process to easily pull data from an API into CSV or other type of file. Simplicity preferred.

Process:
1. Connect to API interface
2. Query API for data
Query API for Project information
Query API for Employee information
Query API for Client information
Query API for Activities
2a. (Secondary) Query API for Project information with search criteria
By Department?
By Modification Date/Time
2b. (Secondary) Query API for Client information with search criteria
By Modification Date/Time
3. Save queried data. Preferably into CSV files per query.
4. Close connection

If the above can be done without installing additional software on a Windows 10 PC, that would be preferred. Source code required.
