Case Study: Gusto improves API documentation reliability and usability with ReadMe

How Gusto uses ReadMe to manage multiple APIs and keep their customers payroll-compliant

Gusto used ReadMe to manage documentation and resources across its two APIs as it expanded its developer ecosystem through Gusto Embedded and partner integrations. The team needed a reliable way to support both business and engineering users, explain payroll compliance requirements, and replace a previous documentation setup that was struggling with downtime, inconsistent updates, and limited analytics.

With ReadMe, Gusto built one developer hub with separate projects for each API, along with guides, tutorials, code samples, search, a changelog, suggested edits, and Okta integration for teammate licenses. ReadMe helped Gusto differentiate 60 shared endpoints, keep documentation current, and give developers a better way to explore and test the APIs, resulting in documentation the team describes as more reliable, streamlined, and usable.
