Workflows
Durable workflow execution
Build complex, long-running workflows that survive failures. Each step is tracked, with automatic retries and the ability to resume from where you left off.

Workflows survive server restarts and failures automatically.
Step Tracking
Monitor progress with detailed step-by-step execution logs.
Automatic Retries
Failed steps are automatically retried with exponential backoff.
Manual Triggers
Start workflows manually or automatically from events.
Workflow Definition
Define multi-step workflows with automatic durability.

onboarding: {
handler: async ({ input, step }) => {
