Greenspark Authentication

Authentication

Greenspark authenticates every API call with a single API key sent in the x-api-key request header. Keys are created in the Greenspark dashboard and are environment-bound: a sandbox key only works against the sandbox host and a production key only against production. No OAuth2/OIDC is offered.

Greenspark secures its APIs with apiKey across 1 declared security scheme, as derived from its OpenAPI definitions.
