  title: Inngest REST Account Events API
  description: 'The Inngest REST API spans two surfaces: the v1 event ingestion and run inspection API used by SDKs and ad-hoc clients, and the v2 management API that covers accounts, environments, apps, webhooks, keys, function invocation, run summaries, and trace trees. Together these endpoints expose Inngest''s event-driven, durable execution platform for background jobs, workflows, and AI agent orchestration.'
