Frequently asked questions
Eddy scores F on the API Report Card. No publicly documented API. Eddy integrates through roughly a dozen curated partners such as QuickBooks Online, Checkr, and 401GO, and Eddy Payroll itself runs on Check's APIs. There is no developer portal, OpenAPI spec, OAuth flow, webhooks, or SDKs.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
