Examples and SDKs for ZITADEL

You can integrate Zitadel quickly into your application and be up and running within minutes. To achieve your goals as fast as possible, we provide you with SDKs, Example Repositories and Guides.

The SDKs and integration depend on the framework and language you are using.

In addition to our officially maintained examples, we also list community-contributed implementations. These examples are provided by external developers and are not maintained by us. While we believe they can be valuable resources and showcase diverse approaches, we cannot guarantee their completeness, functionality, or continued support. If you encounter issues with a community-contributed example, please contact the respective maintainers directly. We provide this list for informational purposes and to foster community engagement, but we do not assume responsibility for these external implementations.

Management Clients

Automate and manage your ZITADEL instance programmatically. These clients are built for Machine-to-Machine (M2M) communication, allowing your backend services to perform administrative tasks without human intervention.

ZITADEL SDKs

ZITADEL SDKs are purpose-built to provide a deep, idiomatic integration into your specific framework. While standard OIDC libraries handle basic authentication, Zitadel SDKs act as a powerful abstraction layer, streamlining complex identity tasks and providing direct access to the ZITADEL core platform.

OIDC Libraries

OIDC is a standard for authentication and most languages and frameworks do provide an OIDC library which can be easily integrated into your application. If we do not provide a specific example, SDK, or guide, we strongly recommend using existing authentication libraries for your language or framework instead of building your own. Certified libraries have undergone rigorous testing and validation to ensure high security and reliability. There are many recommended libraries available, this saves time and ensures that users' data is well-protected.

Example Applications

• B2B customer portal: Showcase the use of personal access tokens in a B2B environment. Uses Next.js Framework.
• Introspection: Python examples for securing an API and invoking it as a service account
• Fine-grained authorization: Leverage actions, custom metadata, and claims for attribute-based access control

Missing Management Client

Is your language/framework missing? Fear not, you can generate your gRPC API Client with ease.

1. Make sure to install buf
2. Create a buf.gen.yaml and configure the plugins you need
3. Run buf generate https://github.com/zitadel/zitadel#format=git,tag=v2.23.1 (change the versions to your needs)

Let us make an example with Ruby. Any other supported language by buf will work as well. Consult the buf plugin registry for more ideas.

Example with Ruby

With gRPC, we usually need to generate the client stub and the messages/types. This is why we need two plugins. The plugin grpc/ruby generates the client stub and the plugin protocolbuffers/ruby takes care of the messages/types.

version: v1
plugins:
  - plugin: buf.build/grpc/ruby
    out: gen
  - plugin: buf.build/protocolbuffers/ruby
    out: gen

If you now run buf generate https://github.com/zitadel/zitadel#format=git,tag=v2.23.1 in the folder where your buf.gen.yaml is located you should see the folder gen appear.

If you run ls -la gen/zitadel/ you should see something like this:

ffo@ffo-pc:~/git/zitadel/ruby$ ls -la gen/zitadel/
