Overview

Build robust integrations with external services using standardized patterns for API calls, error handling, authentication, and data transformation.

When to Use

• Integrating payment processors (Stripe, PayPal)
• Using messaging services (SendGrid, Twilio)
• Connecting to analytics platforms (Mixpanel, Segment)
• Syncing with storage services (AWS S3, Google Cloud)
• Integrating CRM systems (Salesforce, HubSpot)
• Building multi-service architectures

Quick Start

Minimal working example:

const axios = require("axios");

class ThirdPartyClient {
  constructor(config) {
    this.apiKey = config.apiKey;
    this.baseUrl = config.baseUrl;
    this.timeout = config.timeout || 30000;
    this.retryAttempts = config.retryAttempts || 3;
    this.retryDelay = config.retryDelay || 1000;
    this.client = axios.create({
      baseURL: this.baseUrl,
      timeout: this.timeout,
      headers: {
        Authorization: `Bearer ${this.apiKey}`,
        "Content-Type": "application/json",
      },
    });
  }

  async request(method, endpoint, data = null, options = {}) {
    let lastError;

    for (let attempt = 0; attempt < this.retryAttempts; attempt++) {
      try {
        const response = await this.client({
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Implement retry logic with exponential backoff
• Validate webhook signatures
• Log all API interactions
• Use environment variables for secrets
• Transform API responses to internal models
• Implement circuit breakers for critical services
• Monitor API quota and rate limits
• Add proper error handling
• Use timeouts appropriately
• Test with sandbox/test API keys

❌ DON'T

• Hardcode API keys
• Retry all errors indefinitely
• Log sensitive data
• Trust unvalidated webhook data
• Ignore rate limits
• Make synchronous blocking calls
• Expose vendor-specific details to clients
• Skip error handling
• Use production keys in tests
