Integrate the Symmetry I-9 API (Symmetry I-9, powered by WorkBright) to run remote Section 1/Section 2 Form I-9 verification and E-Verify case management from a partner HR platform.

Steps

1. Authenticate by POSTing your Symmetry-provided api-key to https://api.symmetry.com/authentication/login to obtain a Bearer access token for system-level calls.
2. Register the employer via the /employers POST endpoint (including a webhook.callbackUrl for event notifications) to receive an employerId, then register the employee and administrator records.
3. Configure E-Verify for the employer if the employer participates, then generate a one-time employee session token via POST /employers/{employerId}/employees/{employeeId}/generateToken.
4. Embed the returned embeddedUri in an <iframe> with allow="geolocation *; camera *" and sandbox tokens (allow-scripts, allow-same-origin, allow-popups, allow-forms, allow-storage-access-by-user-activation) so the employee can complete Section 1/Section 2 with in-browser document scanning.
5. Subscribe to webhooks (employee.section1Complete, employee.i9Complete, employee.everifyCaseUpdate, employee.upcomingExpiration) instead of polling to track workflow progress.
6. On an employee.everifyCaseUpdate webhook with status pending_referral, fetch full case detail via GET /employers/{employerId}/everifyCases/{id} to retrieve the fanUrl and deadlineOn, then launch the administrator embedded UI via the everifyCases/generateUri endpoint to present the Further Action Notice.
