Version: 8.9 (unreleased)

Overview

You can use gRPC — a high-performance, cross-platform remote procedure call (RPC) framework — to communicate with the Orchestration Cluster.

Why use gRPC?​

Using this API may be beneficial if your use-case requires low-latency or high-throughput communication.

Benefits of gRPC include:

  • Low-latency, high-throughput communication
  • Bidirectional streaming for efficient microservices integration
  • Ideal for scalable, event-driven process automation

Key capabilities​

  • Activate jobs
  • Create and cancel process instances
  • Manage workflows and more

See Zeebe API RPCs for all available operations. Additionally, review technical error handling for a closer look at business logic errors, or Postman to experiment with the API.

Authentication​

Authentication for the Zeebe API (gRPC) depends on your environment and how you deploy Camunda 8. You can find more details in the Authentication guide.
