post https://app.nayya.com/api/employees//additional_benefit_eligibility
This endpoint exposes eligibility management for additional plan benefits for employees. Additional Benefits are different from plans, as they exist at the employer level.
Through this endpoint, you specify a unique set of additional benefits per employee.
Also note that if eligibility changes in your system, then you will need to update any and all employees, one-by-one, in the Nayya system to get things consistent.
