What it is

Build and manage workflows that can handle tasks in the background.

Real use case example

"A founder of a new e-commerce startup wants to automatically fulfill orders and send shipping updates to customers. They create a Conductor workflow that connects to their Stripe account, Notion database, and email service, and set it up to run whenever a new order is placed. The workflow then adds the customer to the Notion database and sends a shipping update to their email. After a few weeks, the founder notices the automation is reliable and saves them a significant amount of time."

When to use it
  • โ€ขWhen building a microservices-based application that requires reliable workflow execution
  • โ€ขWhen integrating AI agents into a larger application workflow
  • โ€ขWhen needing to ensure fault-tolerant execution of critical application tasks
Ready-to-paste prompt
curl -X POST -H 'Content-Type: application/json' -d '{"name":"my_workflow","description":"example workflow","tasks":[{"name":"task1","taskReferenceName":"task1","type":"SIMPLE"}]}' http://localhost:8080/api/metadata/workflow
Heads up: Conductor requires Java 11 or later to run, and the 'gradle' build tool must be installed and configured on the system before building and running the Conductor server
