  title: Authlete Authorization Endpoint Grant Management Endpoint API
  description: "Welcome to the **Authlete API documentation**. Authlete is an **API-first service** where every aspect of the \nplatform is configurable via API. This documentation will help you authenticate and integrate with Authlete to \nbuild powerful OAuth 2.0 and OpenID Connect servers.\n\nAt a high level, the Authlete API is grouped into two categories:\n\n- **Management APIs**: Enable you to manage services and clients.\n- **Runtime APIs**: Allow you to build your own Authorization Servers or Verifiable Credential (VC) issuers.\n\n## \U0001F310 API Servers\n\nAuthlete is a global service with clusters available in multiple regions across the world:\n\n- \U0001F1FA\U0001F1F8 **US**: `https://us.authlete.com`\n- \U0001F1EF\U0001F1F5 **Japan**: `https://jp.authlete.com`\n- \U0001F1EA\U0001F1FA **Europe**: `https://eu.authlete.com`\n- \U0001F1E7\U0001F1F7 **Brazil**: `https://br.authlete.com`\n\nOur customers can host their data in the region that best meets their requirements.\n\n## \U0001F511 Authentication\n\nAll API endpoints are secured using **Bearer token authentication**. You must include an access token in every request:\n\n```\nAuthorization: Bearer YOUR_ACCESS_TOKEN\n```\n\n### Getting Your Access Token\n\nAuthlete supports two types of access tokens:\n\n**Service Access Token** - Scoped to a single service (authorization server instance)\n\n1. Log in to [Authlete Console](https://console.authlete.com)\n2. Navigate to your service → **Settings** → **Access Tokens**\n3. Click **Create Token** and select permissions (e.g., `service.read`, `client.write`)\n4. Copy the generated token\n\n**Organization Token** - Scoped to your entire organization\n\n1. Log in to [Authlete Console](https://console.authlete.com)\n2. Navigate to **Organization Settings** → **Access Tokens**\n3. Click **Create Token** and select org-level permissions\n4. Copy the generated token\n\n> ⚠️ **Important Note**: Tokens inherit the permissions of the account that creates them. Service tokens can only \n> access their specific service, while organization tokens can access all services within your org.\n\n### Token Security Best Practices\n\n- **Never commit tokens to version control** - Store in environment variables or secure secret managers\n- **Rotate regularly** - Generate new tokens periodically and revoke old ones\n- **Scope appropriately** - Request only the permissions your application needs\n- **Revoke unused tokens** - Delete tokens you're no longer using from the console\n\n### Quick Test\n\nVerify your token works with a simple API call:\n\n```bash\ncurl -X GET https://us.authlete.com/api/service/get/list \\\n  -H \"Authorization: Bearer YOUR_ACCESS_TOKEN\"\n```\n\n## \U0001F393 Tutorials\n\nIf you're new to Authlete or want to see sample implementations, these resources will help you get started:\n\n- [Getting Started with Authlete](https://www.authlete.com/developers/getting_started/)\n- [From Sign-Up to the First API Request](https://www.authlete.com/developers/tutorial/signup/)\n\n## \U0001F6E0 Contact Us\n\nIf you have any questions or need assistance, our team is here to help:\n\n- [Contact Page](https://www.authlete.com/contact/)\n"
