Inngest Events

When

Use when designing event-driven workflows, decoupling services, implementing fan-out (one trigger, many downstream handlers), implementing idempotent event handling with IDs, or handling at-least-once delivery from external sources like Stripe webhooks. Covers Inngest event schema, payload format, naming conventions, IDs for idempotency, the ts param, fan-out patterns, and system events like inngest/function.failed.
