Integrate Gusto Into Your Product Without an API
The Integration Barrier
Gusto has a public API, but integrating it into your product means registering as a Gusto developer partner, going through OAuth 2.0 app review, handling token refresh logic, and building the data pipeline yourself. For payroll data — pay stubs, benefits, headcount — that’s a significant compliance and engineering investment before you can show a customer a single number. Deck gives you a single endpoint. Connect a customer’s Gusto account, define what you need, and get structured payroll data back without building or maintaining the integration yourself.

FAQ
Does Gusto have a public API?
Gusto offers a developer API, but getting access means registering as a partner and clearing an OAuth app review. Deck sits in front of that process so you don’t have to.
What Gusto data can Deck extract?
Payroll runs, pay stubs, benefits enrollment, contractor payments, headcount, department structure, and time-off balances — returned as structured JSON to your endpoint.
Can Deck pull Gusto data for multiple customers at once?
Yes. Each customer account gets its own authenticated session; your product calls one endpoint and gets back whichever account’s data you need.
How does Deck handle Gusto’s authentication?
Credentials go into Deck Vault, which encrypts them at rest and resolves MFA challenges automatically — no manual login required at runtime.
Is payroll data secure with Deck?
Data is extracted and forwarded to your specified endpoint within the session. Deck doesn’t store it once delivery is confirmed.
