API Integration

Architecture and patterns for integrating with backend services

API Integration

Overview

API integration is a critical aspect of mobile applications, providing the connection between your app and backend services. This section documents our approach to API client architecture, authentication flows, error handling strategies, request queueing patterns, and guidance for setting up multi-API configurations.

Key API Documentation

API Client Architecture

Defines our established patterns for API client implementation, covering base clients, interceptors, and how to structure domain-specific API services.

Authentication Architecture

Details token management, session handling, and secure authentication flows, building upon the core API client structure.

Error Handling Architecture

Our comprehensive strategy for managing errors, including custom error classes, propagation patterns, and user-friendly messaging.

API Client with Request Queueing

Explains the pattern for efficiently queueing and retrying API requests, especially during authentication token refresh cycles.

Multi-API Architecture

Guidance on scaling the API client architecture to integrate with multiple distinct API services using flexible authentication strategies.

API Integration Principles

Our API integration architecture follows these core principles:

  1. Separation of Concerns - Clear separation between API client, authentication, and domain-specific services
  2. Centralized Error Handling - Consistent approach to handling and propagating API errors
  3. Transparent Authentication - Authentication handled automatically through interceptors
  4. Request Resilience - Graceful handling of network issues, token expiration, and server errors
  5. Type Safety - Strong TypeScript typing for all API requests and responses

Implementation Philosophy

The API integration layer is designed with these considerations in mind:

  • Performance - Efficient request handling, caching, and data transformation
  • Security - Secure storage of tokens and credentials, protection against common vulnerabilities
  • Testability - Easily mockable API clients and services for testing
  • Developer Experience - Intuitive interfaces and minimal boilerplate for making API calls
