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.
