Integrate Paychex Into Your Product Without an API
The Integration Barrier
Paychex has an API, but accessing it requires going through Paychex’s partner program — a certification track designed for established ISVs, not product teams that need payroll data flowing into their platform quickly. Paychex serves over 700,000 businesses, which means there’s enormous demand for Paychex integrations and a significant gap between what the official API program offers and what most products actually need. Deck pulls structured Paychex data — pay stubs, W-2s, payroll runs — for your product without partner certification.

FAQ
Does Paychex have a public API?
Paychex has an API, but it’s gated behind their partner program — a certification track designed for established ISVs, not product teams that need payroll data in the near term. Deck skips that line.
What Paychex data can Deck extract?
Pay stubs, payroll run summaries, W-2s and other tax forms, employee census records, time and attendance data, and benefits deduction details.
Does Deck work across Paychex Flex and other Paychex products?
Yes. Deck connects using the account holder’s credentials. Whichever Paychex product your customer uses, the extraction process is the same.
Can Deck pull Paychex data for multiple employer accounts?
Yes. Each employer is an isolated session in Deck. From your product’s perspective it’s a single parameterized API call.
How does Deck handle Paychex’s security requirements?
Deck Vault encrypts credentials and resolves MFA automatically at login. No one needs to manually authenticate at runtime.
