Develop with Dapr APIs
Dapr exposes reusable building blocks — service invocation, state management, pub/sub messaging, jobs, secrets, and more — through language SDKs and an HTTP/gRPC API. On Diagrid Catalyst, these APIs are backed by managed components, so your code can swap state stores or message brokers through configuration rather than code changes.
Pick your language below to see SDK-specific guides. If you're new to Dapr's building blocks, the Dapr API quickstarts walk through service invocation, state, and pub/sub in under 15 minutes each.
