# Authorization for Go applications

Integrate Cerbos with your Go application using the gRPC-native SDK. Make strongly typed authorization checks with full context.Context support.

- **gRPC-native client** — Built directly on gRPC for efficient binary serialization and low-latency communication with the Cerbos PDP
- **Strongly typed with context.Context** — Pass context.Context for cancellation and deadlines, and work with strongly typed request and response structs throughout
- **Idiomatic Go API** — Follows Go conventions with exported types, error returns, and a builder pattern for constructing authorization requests

## What is Cerbos?

Cerbos is an enterprise authorization solution built to secure access across complex, distributed environments, SaaS products, and regulated systems.

It externalizes authorization logic from application code, making access control consistent and centrally managed across all your services. Instead of scattering permission checks throughout your codebase, you make a single API call to the Cerbos PDP.

Authorization policies are written in human-readable YAML supporting RBAC, ABAC, and conditional rules. They live outside your application and can be updated, tested, and deployed independently.

The Go SDK makes integrating Cerbos straightforward, checking authorization is as simple as calling a function, and the stateless PDP scales horizontally with your infrastructure.

### How to authorize with the Go SDK

1. **Install the Go SDK.** Add the SDK to your project with `go get github.com/cerbos/cerbos-sdk-go`.
1. **Initialize the Cerbos client.** Create a new client with `cerbos.New()`, pointing it at your Cerbos PDP instance running as a sidecar, remote service, or connected via Cerbos Hub.
1. **Call CheckResources().** Pass a `context.Context`, principal, resource, and actions. The SDK builds the gRPC request and returns a strongly typed response.
1. **Cerbos returns allow or deny.** The PDP evaluates your YAML policies and returns a decision your application can enforce immediately.

## FAQ

### How do I use the Cerbos Go SDK?

Add the SDK with `go get github.com/cerbos/cerbos-sdk-go`, create a client pointing at your Cerbos PDP, and call CheckResources with a context.Context, principal, resource, and actions. The SDK uses gRPC natively and returns strongly typed responses.

### Does the Go SDK support gRPC?

Yes. The Go SDK is built on gRPC natively, giving you efficient binary serialization and streaming capabilities. It also supports connecting over HTTP if needed.

### Is the Go SDK open source?

Yes. All Cerbos SDKs are open source and available on GitHub. They are actively maintained and kept up to date with the latest Cerbos PDP features.
