Integrate Justworks Into Your Product Without an API
The Integration Barrier
Justworks is a PEO platform — it handles payroll, benefits, compliance, and HR for small and mid-size businesses. Unlike Gusto or ADP, Justworks does not offer a broadly accessible public API for third-party products to build on. If your product serves customers who run on Justworks and you need payroll, benefits, or employee data, there’s no official integration path — only manual exports. Deck changes that. It logs into Justworks using your customer’s credentials and pulls the data your product needs, structured and ready to use.

FAQ
Does Justworks have a public API?
No. Justworks doesn’t expose an integration API for third-party products, which leaves manual CSV exports as the only option — until Deck. Deck reads directly from the Justworks portal.
What Justworks data can Deck extract?
Payroll summaries, pay stubs, benefits enrollment across health and retirement plans, PEO compliance documents, employee profiles, and time-off balances.
Does Deck work for products serving small businesses on Justworks?
Yes. Even without a native API, Deck can cover an entire customer base running Justworks — each account handled in its own session.
How does Deck handle Justworks’ authentication?
Deck Vault encrypts credentials and manages the login sequence, including any MFA steps Justworks requires.
Can Deck pull Justworks data on a recurring schedule?
Yes — daily, weekly, or on-demand. Set the cadence once; Deck handles the rest without any manual intervention.
