Maven Central

Installation

Gradle

implementation group: 'dev.warrant', name: 'warrant-java', version: '4.2.0'

Maven

<dependency>
  <groupId>dev.warrant</groupId>
  <artifactId>warrant-java</artifactId>
  <version>4.2.0</version>
</dependency>

Usage

public static void main(String[] args) throws WarrantException, IOException {
    String apiKey = "YOUR_KEY";
    WarrantClient client = new WarrantClient(WarrantConfig.withApiKey(apiKey));

    // Create users, roles, permissions
    User user = client.createUser();
    Role adminRole = client.createRole(new Role("admin", "Admin", "Admin role"));
    Permission createPermission = client.createPermission(new Permission("create-report", "Create Report" "Permission to create reports"));

    // RBAC example
    client.assignPermissionToRole(createPermission, adminRole);
    client.assignRoleToUser(adminRole, user);
    client.checkUserHasPermission(user, "create-report"); // returns true
}

Configuring API Endpoints

By default, the SDK makes requests to api.warrant.dev. You can override this endpoint, as well as a check endpoint (if using Warrant Edge) via a WarrantConfig object passed to the client:

public static void main(String[] args) throws WarrantException, IOException {
    String apiKey = "YOUR_KEY";
    // Initialize api endpoint to https://api.warrant.dev and check endpoint to "http://localhost:3000" (local Edge instance)
    WarrantClient client = new WarrantClient(new WarrantConfig(apiKey, "https://api.warrant.dev", "http://localhost:3000"));
}

We’ve used a random API key in these code examples. Replace it with your actual API keys to test this code through your own Warrant account.

For more information on how to use the Warrant API, please refer to the Warrant API reference.

Note that we may release new minor and patch versions of this library with small but backwards-incompatible fixes to the type declarations. These changes will not affect Warrant itself.
