POST
to /employees
to create an Employee,
to /vacancies
to create a Vacancy). The sequence diagram below shows the flow
for a single Employee. Its structure would be identical for other Entity types,
and adding multiple Employees is just a matter of repeating the flow.
After the initial creation, the Entity can be updated through its
Entity-specific endpoint, e.g. /employees/101
for an Employee with ID 101.
PUT
request to respectively
the /employees/{external_id}/skill_profile
and /vacancies/{external_id}/skill_profile
endpoint.
