Protocol Reference

This section provides a deep dive into the internal workings of the Dapr runtime. It is intended for maintainers, contributors, and anyone interested in the low-level implementation details of Dapr’s building blocks.

Unlike the user-facing API reference, these documents focus on:

• How the runtime processes requests.
• Internal state transitions.
• Interaction with component interfaces.
• Protocol-level details (gRPC and HTTP).
