Development

The most comprehensive User Management Platform

The Clerk Java library provides convenient access to the Clerk REST API from from a Java application. The library includes type definitions for all request params and response fields, and is powered by Apache Httpclient.

Summary

Clerk Backend API: The Clerk REST Backend API, meant to be accessed by backend servers.

Versions

When the API changes in a way that isn't compatible with older versions, a new version is released. Each version is identified by its release date, e.g. 2024-10-01. For more information, please see Clerk API Versions.

Please see https://clerk.com/docs for more information.

More information about the API can be found at https://clerk.com/docs

SDK Installation

Getting started

JDK 11 or later is required.

The samples below show how a published SDK artifact is used:

Gradle:

implementation 'com.clerk:backend-api:2.0.0'

Maven:

<dependency>
    <groupId>com.clerk</groupId>
    <artifactId>backend-api</artifactId>
    <version>2.0.0</version>
</dependency>

How to build

After cloning the git repository to your file system you can build the SDK artifact from source to the build directory by running ./gradlew build on *nix systems or gradlew.bat on Windows systems.

If you wish to build from source and publish the SDK artifact to your local Maven repository (on your filesystem) then use the following command (after cloning the git repo locally):

On *nix:

./gradlew publishToMavenLocal -Pskip.signing

On Windows:

gradlew.bat publishToMavenLocal -Pskip.signing

SDK Example Usage

Example

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetPublicInterstitialRequest;
import com.clerk.backend_api.models.operations.GetPublicInterstitialResponse;
import java.lang.Exception;

public class Application {

    public static void main(String[] args) throws Exception {

        Clerk sdk = Clerk.builder()
            .build();

        GetPublicInterstitialRequest req = GetPublicInterstitialRequest.builder()
                .build();

        GetPublicInterstitialResponse res = sdk.miscellaneous().getPublicInterstitial()
                .request(req)
                .call();

        // handle response
    }
}

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
`bearerAuth`	http	HTTP Bearer

To authenticate with the API the bearerAuth parameter must be set when initializing the SDK client instance. For example:

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetPublicInterstitialRequest;
import com.clerk.backend_api.models.operations.GetPublicInterstitialResponse;
import java.lang.Exception;

public class Application {

    public static void main(String[] args) throws Exception {

        Clerk sdk = Clerk.builder()
                .bearerAuth("<YOUR_BEARER_TOKEN_HERE>")
            .build();

        GetPublicInterstitialRequest req = GetPublicInterstitialRequest.builder()
                .build();

        GetPublicInterstitialResponse res = sdk.miscellaneous().getPublicInterstitial()
                .request(req)
                .call();

        // handle response
    }
}

Request Authentication

Use the authenticateRequest method to authenticate a request from your app's frontend (when using a Clerk frontend SDK) to Clerk's Backend API. For example the following utility function checks if the user is effectively signed in:

import java.net.http.HttpRequest;
import com.clerk.backend_api.helpers.jwks.AuthenticateRequest;
import com.clerk.backend_api.helpers.jwks.AuthenticateRequestOptions;
import com.clerk.backend_api.helpers.jwks.RequestState;

public class UserAuthentication {

    public static boolean isSignedIn(HttpRequest request) {
        RequestState requestState = AuthenticateRequest.authenticateRequest(request, AuthenticateRequestOptions
                .secretKey(System.getenv("CLERK_SECRET_KEY"))
                .authorizedParty("https://example.com")
                .build());
        return requestState.isSignedIn();
    }

If the request is correctly authenticated, the token's claims are made available in requestState.claims(). Otherwise the reason for the token verification failure is given by requestState.reason().

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, you can provide a RetryConfig object through the retryConfig builder method:

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetPublicInterstitialRequest;
import com.clerk.backend_api.models.operations.GetPublicInterstitialResponse;
import com.clerk.backend_api.utils.BackoffStrategy;
import com.clerk.backend_api.utils.RetryConfig;
import java.lang.Exception;
import java.util.concurrent.TimeUnit;

public class Application {

    public static void main(String[] args) throws Exception {

        Clerk sdk = Clerk.builder()
            .build();

        GetPublicInterstitialRequest req = GetPublicInterstitialRequest.builder()
                .build();

        GetPublicInterstitialResponse res = sdk.miscellaneous().getPublicInterstitial()
                .request(req)
                .retryConfig(RetryConfig.builder()
                    .backoff(BackoffStrategy.builder()
                        .initialInterval(1L, TimeUnit.MILLISECONDS)
                        .maxInterval(50L, TimeUnit.MILLISECONDS)
                        .maxElapsedTime(1000L, TimeUnit.MILLISECONDS)
                        .baseFactor(1.1)
                        .jitterFactor(0.15)
                        .retryConnectError(false)
                        .build())
                    .build())
                .call();

        // handle response
    }
}

If you'd like to override the default retry strategy for all operations that support retries, you can provide a configuration at SDK initialization:

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetPublicInterstitialRequest;
import com.clerk.backend_api.models.operations.GetPublicInterstitialResponse;
import com.clerk.backend_api.utils.BackoffStrategy;
import com.clerk.backend_api.utils.RetryConfig;
import java.lang.Exception;
import java.util.concurrent.TimeUnit;

public class Application {

    public static void main(String[] args) throws Exception {

        Clerk sdk = Clerk.builder()
                .retryConfig(RetryConfig.builder()
                    .backoff(BackoffStrategy.builder()
                        .initialInterval(1L, TimeUnit.MILLISECONDS)
                        .maxInterval(50L, TimeUnit.MILLISECONDS)
                        .maxElapsedTime(1000L, TimeUnit.MILLISECONDS)
                        .baseFactor(1.1)
                        .jitterFactor(0.15)
                        .retryConnectError(false)
                        .build())
                    .build())
            .build();

        GetPublicInterstitialRequest req = GetPublicInterstitialRequest.builder()
                .build();

        GetPublicInterstitialResponse res = sdk.miscellaneous().getPublicInterstitial()
                .request(req)
                .call();

        // handle response
    }
}

Error Handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or raise an exception.

By default, an API error will throw a models/errors/SDKError exception. When custom error responses are specified for an operation, the SDK may also throw their associated exception. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the verify method throws the following exceptions:

Error Type	Status Code	Content Type
models/errors/ClerkErrors	400, 401, 404	application/json
models/errors/SDKError	4XX, 5XX	/

Example

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.errors.ClerkErrors;
import com.clerk.backend_api.models.operations.VerifyClientRequestBody;
import com.clerk.backend_api.models.operations.VerifyClientResponse;
import java.lang.Exception;

public class Application {

    public static void main(String[] args) throws ClerkErrors, Exception {

        Clerk sdk = Clerk.builder()
                .bearerAuth("<YOUR_BEARER_TOKEN_HERE>")
            .build();

        VerifyClientRequestBody req = VerifyClientRequestBody.builder()
                .token("<value>")
                .build();

        VerifyClientResponse res = sdk.clients().verify()
                .request(req)
                .call();

        if (res.client().isPresent()) {
            // handle response
        }
    }
}

Server Selection

Override Server URL Per-Client

The default server can be overridden globally using the .serverURL(String serverUrl) builder method when initializing the SDK client instance. For example:

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetPublicInterstitialRequest;
import com.clerk.backend_api.models.operations.GetPublicInterstitialResponse;
import java.lang.Exception;

public class Application {

    public static void main(String[] args) throws Exception {

        Clerk sdk = Clerk.builder()
                .serverURL("https://api.clerk.com/v1")
            .build();

        GetPublicInterstitialRequest req = GetPublicInterstitialRequest.builder()
                .build();

        GetPublicInterstitialResponse res = sdk.miscellaneous().getPublicInterstitial()
                .request(req)
                .call();

        // handle response
    }
}

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Feel free to open a PR or a Github issue as a proof of concept and we'll do our best to include it in a future release!
