Processout Authentication

Authentication

ProcessOut authenticates every API request with HTTP Basic auth using two project keys: the project ID as the username and a secret API key as the password. Sandbox and production keys are fully separate — the sandbox project ID carries a `test-` prefix and the secret is `key_sandbox_`/`key_test_`; production uses the un-prefixed project ID and a `key_live_` secret. API keys carry per-project permissions set at creation and cannot be edited afterward. The audit-logs endpoint authenticates with the organization ID as username and the API secret as password. Dashboard sign-in additionally supports SAML and OIDC SSO (enterprise).

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