MuleSoft: Client Apps vs Connected Apps
Comparison Study of two types of Apps
In this blog, let’s explore the differences between Client Apps and Connected Apps in the context of MuleSoft and API management. Both concepts are integral to how applications interact with MuleSoft APIs and Services, yet they serve distinct purposes and operate differently.
Client Apps
Client Apps are applications that consume APIs managed by Anypoint Platform. These are typically external applications (end-user applications or services) that rely on APIs to accessdata and services.
Key Characteristics
API Consumers: Client Apps are typically the API consumers. They could be web applications, mobile apps, or other services interacting with APIs to retrieve or send data.
Identification: Each Client App is identified uniquely, usually by an API key or a set of credentials (Client ID/Secret), to manage access to the APIs.
Access Control: Permissions & access levels can be defined for different Client Apps, determining what data and operations they can access through the API.
Rate Limiting and Throttling: Policies such as rate limiting and throttling are often applied to Client Apps to control the number of API requests they can make within a certain period.
Monitoring & Analytics: Usage data, performance metrics, and analytics are often tracked per Client App to understand how the APIs are consumed.
Use Cases
- A mobile banking app using APIs to access user account details and transactions.
- A web application integrating weather APIs to display real-time weather data.
Connected Apps
Connected Apps are applications registered within Anypoint Platform to interact with the Platform’s APIs andservices securely. They are designed to provide controlled access to Anypoint Platform resources using OAuth 2.0.
Key Characteristics
Platform Integration: Connected Apps are designed to integrate with the Anypoint Platform, enabling secure access to various Platform’s services and APIs.
OAuth 2.0 Authorization: These apps use OAuth 2.0 for secure, token-based access to the Platform’s APIs and services.
Granular Permissions: Connected Apps can be configured with specific scopes and permissions, defining precisely what they can access and perform within the Anypoint Platform.
Security: Enhanced security features are available, such as token expiration, scopes, and refresh tokens, to ensure secure interactions with the platform.
Single Sign-On (SSO): Connected Apps can leverage SSO capabilities, allowing seamless access across multiple services with a single authentication.
Use Cases
- A custom dashboard application that integrates with Anypoint Monitoring to display API performance metrics.
- An automation tool that interacts with the Runtime Manager API to deploy and manage Mule applications.
Key Differences
Primary Role
Client Apps primarily act as consumers of APIs.
Connected Apps serve as integrators with the Anypoint Platform.
Authentication
Client Apps typically use API keys, Basic Authentication, or OAuth tokens.
Connected Apps utilize OAuth 2.0 for secure token-based authentication.
Authorization
With Client Apps, access is controlled at the API level, with permissions defined for different endpoints and operations.
With Connected Apps, we employ granular permission settings, allowing precise control over what platform resources and operations the app can access and perform.
Purpose
With Client Apps, the purpose is to access and interact with APIs managed by the platform for various functionalities, such as retrieving data, performing transactions, or invoking services.
Connected Apps aimsto provide secure, authorized access to platform resources, enabling external applications to perform tasks like deployment, monitoring, and management.
Scope of Access
Client Apps are limited to consuming APIs managed by theplatform. They focus on accessing data and executing predefined API operations.
For Connected Apps, it is a broader access to platform resources. They can perform various tasks, including deploying Mule applications, monitoring performance, managing environments, etc.
Security Features
With Client Apps typically involve rate limiting, throttling, and basic security policies to protect APIs.
With Connected Apps, we have enhanced security features like OAuth scopes, token expiration, refresh tokens, and Single Sign-On (SSO).
Integration Points
Client Apps integrate directly with APIs managed by the platform, typically for specific business functions or data retrieval. They are used by end-user applications such as mobile apps, web apps, and other external services.
Connected Apps integrate with the Anypoint Platform’s APIs and services. They are used by tools and applications that need to interact with the platform itself for tasks like automation, deployment, and monitoring.
Management and Configuration
Client Apps are managed primarily through API Manager, where APIs and their access policies are configured. Their configuration focuses on API-level configurations, such as endpoints, request/response formats, and security policies.
Connected Apps are managed within the platform and configuredfor platform resource access. Their configuration involves setting up OAuth clients, defining scopes, and configuring permissions for accessing platform APIs.
Key Commonalities
- Both Client Apps and Connected Apps are designed to ensure secure access to APIs & resources. They implement security protocols such as OAuth 2.0 to authenticate and authorize users and applications.
- Both Client Apps and Connected Apps have permissions to control the dataand services they can access. This ensures they operate within their defined scopes and stay withintheir bounds.
- Both maintain audit logs to track access and activities, providing transparency and accountability in using APIs and platform resources.
- Both apps can be subject to security policies such as rate limiting, IP allowlisting, and data encryption to protect the APIs and the underlying data.
- MuleSoft provides tools and interfaces to simplify the development and management of both Client Apps and Connected Apps, making it easier for developers to work with APIs and platform services.
Conclusion
Understanding the distinct roles of Client Apps and Connected Apps within the MuleSoft ecosystem is essential for optimizing API and platform management strategies.
Organizations can enhance their integration capabilities by appropriately leveraging both Client Apps and Connected Apps, ensuring secure interactions, and maintaining robust control over their APIs and platforms.
