How Merge uses Fern to ship SDKs

Merge is a company that provides Unified APIs for B2B organizations. They offer categories of integrations such as CRM, file storage, HRIS, and ATS. By leveraging Merge's maintenance support and management tooling, organizations can offer more reliable and high-performing integrations. However, building an in-house SDK is time-consuming, error-prone, and ultimately distracting for Merge. They initially used OpenAPI’s SDK Generator but switched to a Fern-based SDK workflow due to its advanced code automation capabilities. This allowed them to create a robust, well-documented SDK that appeals to modern developers. The adoption of Fern has brought numerous benefits such as better and more consistent SDK code generation, cleaner SDK experience, improved documentation, support for unions, and minimized backward compatibility issues.
