Connect API overview - Darwin

The Connect API is the application control plane for products that put Darwin behind their own interface. It manages applications, Sign in with Darwin, linked-agent grants, enrollment, service accounts, app-funded ephemeral work, application balances, and webhooks.

Architecture

The split is intentional: Connect establishes who may act, who funds the work, and where events go. The Product API operates a granted user’s agent.

Integration models
