Most HR teams run into the same wall: their HCM platform — whether it's UKG, SAP, ADP, Workday, or something else — has a built-in I-9 module. It generates the form. But that's where it stops.
HR still manually enters new hire data into a second system — or doesn't, and falls behind
I-9 status lives in a silo that nobody checks until there's a problem
Remote and multi-location hires need Section 2 verification that no HCM module provides
Expiring documents aren't tracked — reverification deadlines get missed
Terminated employee I-9s aren't retained automatically, creating gaps in your audit trail
When ICE shows up with 3 days' notice, pulling audit-ready reports or even a print-view I-9 from your HRIS is a scramble
Making corrections to a completed I-9 is difficult or impossible in most built-in modules
Start date changes, rehires, and terminations create compliance gaps every time someone forgets to update both systems
The fix isn't a better form. It's a connected workflow.
Our API connects your HRIS directly to the i9 Intelligence platform. When a new hire is confirmed in your system, the I-9 process starts automatically. Status updates sync back.
The entire I-9 lifecycle — from Section 1 initiation through E-Verify submission to audit-ready storage — happens without anyone switching between systems or manually entering data.
A new hire triggers in your HRIS. Our API creates the I-9 record, routes it to the right workflow based on hire type (remote, in-person, or partial remote), and sends the employee their Section 1 instructions — all without HR lifting a finger.
Your HRIS always knows where every I-9 stands. Status updates flow back automatically — from Section 1 initiation through completion — so downstream workflows like benefits enrollment and payroll activation aren't waiting on compliance.
Start date changes, location transfers, rehires, terminations — every event in your HRIS triggers the right update in i9 Intelligence. No manual sync. No compliance gaps. No orphan records.
New hires anywhere in the U.S. complete Section 2 over a live video call with a trained i9 Intelligence agent. No notary, no travel, no delay.
Full lifecycle I-9 integration — from new hire initiation through termination. Every hire routed automatically to remote verification.
Complete bidirectional integration covering the full I-9 lifecycle. Audit-grade logging built into the data flow.
Workday and SAP are the two most complex HRIS platforms to integrate with. We've done both. If your platform is simpler — and most are — the integration is even more straightforward.
Every integration starts simple and can grow. Most clients begin with Easy and expand as their needs evolve.
You might be here if: You're doing your first HRIS integration, you have a single location or are fully remote, most hires follow the same process, or you just want to stop manually entering new hires into two systems.
You might be here if: You have multiple locations with a mix of remote and in-person employees, your HRIS tracks work location and remote status, you're tired of manually handling start date changes and rehires, or you've outgrown Easy and keep running into edge cases.
You might be here if: You operate across multiple subsidiaries or business units, you hire at high volume with seasonal ramps, you use separate ATS and HRIS platforms, your compliance team requires audit-grade logging and reconciliation, or your integration team is building middleware and wants full control over the data flow.
Our API handles every event in the employee lifecycle that affects I-9 compliance — not just the initial hire.
1. New Hire I-9 Initiation — HRIS confirms a hire, API creates the I-9 and sends Section 1 instructions
2. Hire Type Routing — Automatically assigns remote, in-person, or partial remote workflow
3. Rehire — Creates a new I-9 record while preserving the prior one for retention
4. Duplicate Prevention — Validates SSN, Employee ID, and Application ID on every create call
5. I-9 Status Sync — Writes current I-9 status back to the employee's HRIS profile
6. Custom Email Domain & Branding — I-9 notifications sent from your company's domain
7. Start Date / Hire Date Change — Adjusts the record and compliance deadlines automatically
8. Location / Unit Transfer — Updates organizational assignment, including backdated transfers
9. Remote Flag Change — Handles workflow re-routing when a hire switches between remote and in-person
10. Record Updates — Name corrections, email changes, SSN fixes — all with full audit trail
11. Data Sovereignty — Clear rules for which system owns which fields. No overwrites.
12. Cancel Onboarding — Removes the record and cancels Section 1 invites for rescinded offers
13. Employee Termination — Sets status to TERMINATED, records date, closes open E-Verify cases
14. Retention Management — I-9 retention periods are calculated automatically from Key dates
“What I love most is how the system handles remote hires. With more teammates working from different locations, this feature has become invaluable for my team to keep everything compliant. The E-Verify integration is seamless, which is a huge time-saver too.”
"The API integration with i9 Intelligence has made a huge difference for our team. Every new hire in the U.S. now receives the same communication and follows a consistent, compliant process pre-day one. It's taken a lot of the manual work and guesswork off our plate. Knowing our I-9s are standardized and audit-ready gives us real peace of mind."
"i9 Intelligence has made compliance so much easier for our team! The platform is intuitive and keeps us organized with automated reminders, which has really helped reduce our risk. It integrates well with our HR systems, and their support team is always SO quick to assist."
Our REST API gives your integration team full control over I-9 lifecycle management — from new hire initiation to termination handling. Every integration includes a sandbox environment, dedicated engineering support, and access to the only I-9 platform with built-in remote Section 2 verification.
Our REST API connects to any HRIS platform that supports outbound API calls — Workday, SAP SuccessFactors, ADP, UKG, Paycor, Paychex, Paylocity, Rippling, Gusto, BambooHR, Ceridian, Oracle HCM, and custom-built systems. We have enterprise-grade production integrations with Workday and SAP, which are the two most complex platforms on the market. If your HRIS can make an HTTP request, we can integrate.
It depends on the complexity. An Easy-tier integration (new hire initiation, status sync, termination) can be live in days. A Medium-tier integration covering the full lifecycle typically takes 2–4 weeks. Enterprise-grade Advanced integrations with bidirectional data flow, bulk operations, and custom routing may take 4–8 weeks. Our team works alongside your IT staff throughout.
Not necessarily. For Easy and Medium integrations, a single developer or integration specialist is usually sufficient. We provide documentation, field mapping guides, and a sandbox environment for testing. For Advanced enterprise integrations, your middleware or integration team will want to be involved, and we'll work directly with them.
Yes. We provide a full sandbox environment with separate credentials that mirrors production functionality. Your team can build and test the entire integration before going live.
Existing I-9 records in i9 Intelligence are not affected by the integration. New records created through the API coexist with records created through the web interface. The duplicate prevention logic ensures that records aren't accidentally duplicated across entry methods.
Yes. The API supports three hire type configurations: Remote (employee completes Section 1 from home, Section 2 via our remote verification service), In-Person (both sections completed at the worksite), and Partial Remote (Section 1 from home, Section 2 on-site). Your HRIS controls which workflow each hire follows.
i9 Intelligence is SOC 2 certified. The API uses JWT Bearer authentication with 60-minute token expiration and environment-specific credentials. All operations are logged in a tamper-evident audit trail. Data is encrypted in transit and at rest. For details on our full security posture, see our Security & Compliance page.
Yes. We support single sign-on through Microsoft Entra ID, Okta, and Auth0, with other providers available upon request. Your team can authenticate into i9 Intelligence using their existing identity provider.
Yes. If your organization has requirements that go beyond our standard API — custom endpoints, specialized workflows, or features specific to your compliance process — we can build them. We work with enterprise clients regularly on custom development, and many of those features become part of the platform for all clients over time.
Built-in I-9 modules from Workday, SAP, and ADP prioritize feature breadth — not deep regulatory compliance. I-9 is a bolt-on for them, not a core capability. Under ICE audit scrutiny, the cracks show up fast: incomplete audit trails, no expiring document tracking, no automatic retention for terminated I-9s, and limited ability to edit or correct a completed form. Even pulling a print-view I-9 or running compliance reports can be a challenge. And none of them provide trained authorized representatives to conduct Section 2 verification on your behalf or handle remote verification.
With our integration, you don't choose between your HRIS and us — you get both. Your HRIS stays your system of record. i9 Intelligence handles the compliance: the verification calls, the audit trail, the E-Verify submission, 27 years of expertise on the edge cases that trip up HR teams. The API connects the two so nothing falls through the cracks. Read more about why most HRIS systems fail at I-9 compliance.
