Security and authentication
Authentication overview
Speakeasy-created SDKs have authentication automatically configured based on the securitySchemes defined in the OpenAPI specification.
APIs authenticated with simple schemes, such as Basic HTTP auth, API keys, and bearer tokens, work out of the box. For APIs using short-lived tokens (OAuth), additional configuration is required to simplify setup.
