Once you've established the employer, you are ready to register the employee (new hire) and employer administrators to the employer, which can happen at any time. As a reminder, employees must be configured before starting an I-9 for that employee.

Register Employee

To establish a new hire, register the employee by calling the /employees endpoint. A successful request will return the employee's id that can then be used to generate the employee's access link to their I-9. Registering an employee can be completed in advance for an employee with a start date in the future, or it can be completed “just in time” right before the I-9 verification process begins.

When registering employees, you will also specify if an employee should not be eligible for Remote I-9 Section 2 verification within the employeeDocumentOptions object. (note: this is only applicable if you have Remote I-9 enabled by default).

Register Administrator

This one-time step is required to set up the employer administrator (HR, Compliance, or other executive functions at the employer) within that company who will administer Forms I-9 and take action on any documentation verification or E-Verify cases. Companies may have more than one administrator and administrators can be created at any time.

To create a new administrator, call the /employers/{employerId}/admins POST endpoint with the administrator details.

A successful call will return the administrator's ID that will then be used to generate the administrator's access to employer embedded experience.
