Symmetrical Payroll rails is RESTful and follows REST conventions.
POST request is used for creating new resources, read data using GET, update with PUT/PATCH and delete with DELETE.

Entities identifiers
Most resources are identified by an ID string, which is in the UUIDv4, i.e. fffca4aa-a801-4807-a4b0-9993273f3ab9

IDs appear in query paths or payload to identify resources.
