Factorial Keys and OAuth API is one of 22 APIs that [Factorial](https://apis.io/providers/factorial-hr/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication and APIKeys. The published artifact set on APIs.io includes API documentation.

Two authentication methods. OAuth2 (authorization code flow at /oauth/authorize and /oauth/token) is used to act on behalf of a user; Credentials/API Keys (x-api-key header) are used to act on behalf of the company with full admin access. API Keys overrule OAuth tokens when both are present on the same request.
