Flexport CI Integration

Overview

Set up CI/CD pipelines for Flexport integrations with automated testing.

Prerequisites

GitHub repository with Actions enabled
Flexport test API key
npm/pnpm project configured

Instructions

Step 1: Create GitHub Actions Workflow

Create .github/workflows/flexport-integration.yml:


name: Flexport Integration Tests

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

env:
  FLEXPORT_API_KEY: ${{ secrets.FLEXPORT_API_KEY }}

jobs:
  test:
    runs-on: ubuntu-latest
    env:
      FLEXPORT_API_KEY: ${{ secrets.FLEXPORT_API_KEY }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm test -- --coverage
      - run: npm run test:integration

Step 2: Configure Secrets


gh secret set FLEXPORT_API_KEY --body "sk_test_***"

Step 3: Add Integration Tests


describe('Flexport Integration', () => {
  it.skipIf(!process.env.FLEXPORT_API_KEY)('should connect', async () => {
    const client = getFlexportClient();
    const result = await client.healthCheck();
    expect(result.status).toBe('ok');
  });
});

Output

Automated test pipeline

Flexport Cost Tuning

Overview

Optimize Flexport costs through smart tier selection, sampling, and usage monitoring.

Prerequisites

Access to Flexport billing dashboard
Understanding of current usage patterns
Database for usage tracking (optional)
Alerting system configured (optional)

Pricing Tiers

Tier	Monthly Cost	Included	Overage
Free	$0	1,000 requests	N/A
Pro	$99	100,000 requests	$0.001/request
Enterprise	Custom	Unlimited	Volume discounts

Cost Estimation


interface UsageEstimate {
  requestsPerMonth: number;
  tier: string;
  estimatedCost: number;
  recommendation?: string;
}

function estimateFlexportCost(requestsPerMonth: number): UsageEstimate {
  if (requestsPerMonth <= 1000) {
    return { requestsPerMonth, tier: 'Free', estimatedCost: 0 };
  }

  if (requestsPerMonth <= 100000) {
    return { requestsPerMonth, tier: 'Pro', estimatedCost: 99 };
  }

  const proOverage = (requestsPerMonth - 100000) * 0.001;
  const proCost = 99 + proOverage;

  return {
    requestsPerMonth,
    tier: 'Pro (with overage)',
    estimatedCost: proCost,
    recommendation: proCost > 500
      ? 'Consider Enterprise tier for volume discounts'
      : undefined,
  };
}

Usage Monitoring


class FlexportUsageMonitor {
  private requestCount = 0;
  private bytesTransferred = 0;
  private alertThreshold: number;

  constructor(monthlyBudget: number) {
    this.alertThreshold = monthlyBudget * 0.8; // 80% warning
  }

  track(request: { bytes: number }) {
    this.requestCount++;
    this.bytesTransferred += request.bytes;

    if (this.estimatedCost() > this.alertThreshold) {
      this.sendAlert('Approaching Flexport budget limit');
    }
  }

  estimatedCost(): number {
    return estimateFlexportCost(this.requestCount).estimatedCost;
  }

  private sendAlert(message: string) {
    // Send to Slack, email, PagerDuty, etc.
  }
}

Cost Reduction Strategies

Step 1: Request Sampling


function shouldSample(samplingRate = 0.1): boolean {
  return Math.random() < samplingRate;
}

// Use for non-critical telemetry
if (shouldSample(0.1)) { // 10% sample
  await flexportClient.trackEvent(event);
}

Step 2: Batching Requests


// Instead of N individual calls
await Promise.all(ids.map(id => flexportClient.get(id)));

// Use batch endpoint (1 call)
await flexportClient.batchGet(ids);

Step 3: Caching (from P16)

Implement Flexport PII handling, data retention, and GDPR/CCPA compliance patterns.

ReadWriteEdit

Flexport Data Handling

Overview

Handle sensitive data correctly when integrating with Flexport.

Prerequisites

Understanding of GDPR/CCPA requirements
Flexport SDK with data export capabilities
Database for audit logging
Scheduled job infrastructure for cleanup

Data Classification

Category	Examples	Handling
PII	Email, name, phone	Encrypt, minimize
Sensitive	API keys, tokens	Never log, rotate
Business	Usage metrics	Aggregate when possible
Public	Product names	Standard handling

PII Detection


const PII_PATTERNS = [
  { type: 'email', regex: /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g },
  { type: 'phone', regex: /\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g },
  { type: 'ssn', regex: /\b\d{3}-\d{2}-\d{4}\b/g },
  { type: 'credit_card', regex: /\b\d{4}[- ]?\d{4}[- ]?\d{4}[- ]?\d{4}\b/g },
];

function detectPII(text: string): { type: string; match: string }[] {
  const findings: { type: string; match: string }[] = [];

  for (const pattern of PII_PATTERNS) {
    const matches = text.matchAll(pattern.regex);
    for (const match of matches) {
      findings.push({ type: pattern.type, match: match[0] });
    }
  }

  return findings;
}

Data Redaction


function redactPII(data: Record<string, any>): Record<string, any> {
  const sensitiveFields = ['email', 'phone', 'ssn', 'password', 'apiKey'];
  const redacted = { ...data };

  for (const field of sensitiveFields) {
    if (redacted[field]) {
      redacted[field] = '[REDACTED]';
    }
  }

  return redacted;
}

// Use in logging
console.log('Flexport request:', redactPII(requestData));

Data Retention Policy

Retention Periods

Data Type	Retention	Reason
API logs	30 days	Debugging
Error logs	90 days	Root cause analysis
Audit logs	7 years	Compliance
PII	Until deletion request	GDPR/CCPA

Automatic Cleanup


async function cleanupFlexportData(retentionDays: number): Promise<void> {
  const cutoff = new Date();
  cutoff.setDate(cutoff.getDate() - retentionDays);

  await db.flexportLogs.deleteMany({
    createdAt: { $lt: cutoff },
    type: { $nin: ['audit', 'compliance'] },
  });
}

// Schedule daily cleanup
cron.schedule('0 3 * * *', () => cleanupFlexportData(30)

Instructions
Step 1: Create Debug Bundle Script

#!/bin/bash
# flexport-debug-bundle.sh

BUNDLE_DIR="flexport-debug-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$BUNDLE_DIR"

echo "=== Flexport Debug Bundle ===" > "$BUNDLE_DIR/summary.txt"
echo "Generated: $(date)" >> "$BUNDLE_DIR/summary.txt"

Step 2: Collect Environment Info

# Environment info
echo "--- Environment ---" >> "$BUNDLE_DIR/summary.txt"
node --version >> "$BUNDLE_DIR/summary.txt" 2>&1
npm --version >> "$BUNDLE_DIR/summary.txt" 2>&1
echo "FLEXPORT_API_KEY: ${FLEXPORT_API_KEY:+[SET]}" >> "$BUNDLE_DIR/summary.txt"

Step 3: Gather SDK and Logs

# SDK version
npm list @flexport/sdk 2>/dev/null >> "$BUNDLE_DIR/summary.txt"

# Recent logs (redacted)
grep -i "flexport" ~/.npm/_logs/*.log 2>/dev/null | tail -50 >> "$BUNDLE_DIR/logs.txt"

# Configuration (redacted - secrets masked)
echo "--- Config (redacted) ---" >> "$BUNDLE_DIR/summary.txt"
cat .env 2>/dev/null | sed 's/=.*/=***REDACTED***/' >> "$BUNDLE_DIR/config-redacted.txt"

# Network connectivity test
echo "--- Network Test ---" >> "$BUNDLE_DIR/summary.txt"
echo -n "API Health: " >> "$BUNDLE_DIR/summary.txt"
curl -s -o /dev/null -w "%{http_code}" https://api.flexport.com/health >> "$BUNDLE_DIR/summary.txt"
echo "" >> "$BUNDLE_DIR/summary.txt"

Step 4: Package Bundle

tar -czf "$BUNDLE_DIR.tar.gz" "$BUNDLE_DIR"
echo "Bundle created: $BUNDLE_DIR.tar.gz"

Output

flexport-debug-YYYYMMDD-HHMMSS.tar.gz archive containing:
summary.txt - Environment and SDK info
logs.txt - Recent redacted logs
config-redacted.txt - Configuration (secrets removed)

Quick Triage

# 1. Check Flexport status
curl -s https://status.flexport.com | jq

# 2. Check our integration health
curl -s https://api.yourapp.com/health | jq '.services.flexport'

# 3. Check error rate (last 5 min)
curl -s localhost:9090/api/v1/query?query=rate(flexport_errors_total[5m])

# 4. Recent error logs
kubectl logs -l app=flexport-integration --since=5m | grep -i error | tail -20

Decision Tree

Flexport API returning errors?
├─ YES: Is status.flexport.com showing incident?
│   ├─ YES → Wait for Flexport to resolve. Enable fallback.
│   └─ NO → Our integration issue. Check credentials, config.
└─ NO: Is our service healthy?
    ├─ YES → Likely resolved or intermittent. Monitor.
    └─ NO → Our infrastructure issue. Check pods, memory, network.

Immediate Actions by Error Type
401/403 - Authentication

# Verify API key is set
kubectl get secret flexport-secrets -o jsonpath='{.data.api-key}' | base64 -d

# Check if key was rotated
# → Verify in Flexport dashboard

# Remediation: Update secret and restart pods
kubectl create secret generic flexport-secrets --from-literal=api-key=NEW_KEY --dry-run=client -o yaml | kubectl apply -f -
kubectl rollout restart deployment/flexport-integration

429 - Rate Limited

# Check rate limit headers
curl -v https://api.flexport.com 2>&1 | grep -i rate

# Enable request queuing
kubectl set env deployment/flexport-integration RATE_LIMIT_MODE=queue

# Long-term: Contact Flexport for limit increase

500/503 - Flexport Errors

# Enable graceful degradation
kubectl set env deployment/flexport-integration FLEXPORT_FALLBACK=true

# Notify users of degraded service
# Update status page

# Monitor Flexport status for resolution

├── .env.local              # Local secrets (git-ignored)
├── .env.example            # Template for team
└── package.json

Step 2: Configure Environment

# Copy environment template
cp .env.example .env.local

# Install dependencies
npm install

# Start development server

Step 3: Setup Hot Reload

{
  "scripts": {
    "dev": "tsx watch src/index.ts",
    "test": "vitest",
    "test:watch": "vitest --watch"
  }
}

Step 4: Configure Testing

import { describe, it, expect, vi } from 'vitest';
import { FlexportClient } from '../src/flexport/client';

describe('Flexport Client', () => {
  it('should initialize with API key', () => {
    const client = new FlexportClient({ apiKey: 'test-key' });
    expect(client).toBeDefined();
  });
});

Output

Pre-Migration Assessment
Step 1: Current State Analysis

# Document current implementation
find . -name "*.ts" -o -name "*.py" | xargs grep -l "flexport" > flexport-files.txt

# Count integration points
wc -l flexport-files.txt

# Identify dependencies
npm list | grep flexport
pip freeze | grep flexport

Step 2: Data Inventory

interface MigrationInventory {
  dataTypes: string[];
  recordCounts: Record<string, number>;
  dependencies: string[];
  integrationPoints: string[];
  customizations: string[];
}

async function assessFlexportMigration(): Promise<MigrationInventory> {
  return {
    dataTypes: await getDataTypes(),
    recordCounts: await getRecordCounts(),
    dependencies: await analyzeDependencies(),
    integrationPoints: await findIntegrationPoints(),
    customizations: await documentCustomizations(),

Caching Strategy
Response Caching

import { LRUCache } from 'lru-cache';

const cache = new LRUCache<string, any>({
  max: 1000,
  ttl: 60000, // 1 minute
  updateAgeOnGet: true,
});

async function cachedFlexportRequest<T>(
  key: string,
  fetcher: () => Promise<T>,
  ttl?: number
): Promise<T> {
  const cached = cache.get(key);
  if (cached) return cached as T;

  const result = await fetcher();
  cache.set(key, result, { ttl });
  return result;
}

Redis Caching (Distributed)

import Redis from 'ioredis';

const redis = new Redis(process.env.REDIS_URL);

async function cachedWithRedis<T>(
  key: string,
  fetcher: () => Promise<T>,
  ttlSeconds = 60
): Promise<T> {
  const cached = await redis.get(key);
  if (cached) return JSON.parse(cached);

  const result = await fetcher();
  await redis.setex(key, ttlSeconds, JSON.stringify(result));
  return result;
}

Request Batching

import DataLoader from 'dataloader';

const flexportLoader = new DataLoader<string, any>(
  async (ids) => {
    // Batch fetch from Flexport
    const results = await flexportClient.batchGet(ids);
    return ids.map(id => results.find(r => r.id === id) || null);
  },
  {
    maxBatchSize: 100,
    batchScheduleFn: callback => setTimeout(callback, 10),
  }
);

// Usage - automatically batched
const [item1, item2, item3] = await Promise.all([
  flexportLoader.load('id-1'),
  flexportLoader.load('id-2'),
  flexportLoader.load('id-3'),
]);

Connection Optimization

import { Agent } from 'https';

// Keep-alive connection pooling
const agent = new Agent({
  keepAlive: true,
  maxSockets: 10,
  maxFreeSockets: 5,
  timeout: 30000,
});

const client = new FlexportClient({
  apiKey: process.env.FLEXPORT_API_KEY!,
  httpAgent: agent,
});

[ ] Monitoring/alerting configured
[ ] Circuit breaker pattern implemented
[ ] Graceful degradation configured

Step 4: Documentation Requirements

[ ] Incident runbook created
[ ] Key rotation procedure documented
[ ] Rollback procedure documented
[ ] On-call escalation path defined

Step 5: Deploy with Gradual Rollout

# Pre-flight checks
curl -f https://staging.example.com/health
curl -s https://status.flexport.com

# Gradual rollout - start with canary (10%)
kubectl apply -f k8s/production.yaml
kubectl set image deployment/flexport-integration app=image:new --record
kubectl rollout pause deployment/flexport-integration

# Monitor canary traffic for 10 minutes
sleep 600
# Check error rates and latency before continuing

# If healthy, continue rollout to 50%
kubectl rollout resume deployment/flexport-integration
kubectl rollout pause deployment/flexport-integration
sleep 300

# Complete rollout to 100%
kubectl rollout resume deployment/flexport-integration
kubectl rollout status deployment/flexport-integration

Step 2: Implement Exponential Backoff with Jitter

async function withExponentialBackoff<T>(
  operation: () => Promise<T>,
  config = { maxRetries: 5, baseDelayMs: 1000, maxDelayMs: 32000, jitterMs: 500 }
): Promise<T> {
  for (let attempt = 0; attempt <= config.maxRetries; attempt++) {
    try {
      return await operation();
    } catch (error: any) {
      if (attempt === config.maxRetries) throw error;
      const status = error.status || error.response?.status;
      if (status !== 429 && (status < 500 || status >= 600)) throw error;

      // Exponential delay with jitter to prevent thundering herd
      const exponentialDelay = config.baseDelayMs * Math.pow(2, attempt);
      const jitter = Math.random() * config.jitterMs;
      const delay = Math.min(exponentialDelay + jitter, config.maxDelayMs);

      console.log(`Rate limited. Retrying in ${delay.toFixed(0)}ms...`);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error('Unreachable');
}

Step 3: Add Idempotency Keys

import { v4 as uuidv4 } from 'uuid';
import crypto from 'crypto';

// Generate deterministic key from operation params (for safe retries)
function generateIdempotencyKey(operation: string, params: Record<string, any>): string {
  const data = JSON.stringify({ operation, params });
  return crypto.createHash('sha256').update(data).digest('hex');
}

async function idempotentRequest<T>(
  client: FlexportClient,
  params: Record<string, any>,
  idempotencyKey?: string  // Pass existing key for retries
): Promise<T> {
  // Use provided key (for retries) or generate deterministic key from params
  const key = idempotencyKey || generateIdempotencyKey(params.method || 'POST', params);
  return client.request({
    ...params,
    headers: { 'Idempotency-Key': key, ...params.headers },
  });
}

Output

Reliable API calls with automatic retry
Idempotent requests preventing duplicates
Rate limit headers properly handled

Key Components
Step 1: Client Wrapper

// src/flexport/client.ts
export class FlexportService {
  private client: FlexportClient;
  private cache: Cache;
  private monitor: Monitor;

  constructor(config: FlexportConfig) {
    this.client = new FlexportClient(config);
    this.cache = new Cache(config.cacheOptions);
    this.monitor = new Monitor('flexport');
  }

  async get(id: string): Promise<Resource> {
    return this.cache.getOrFetch(id, () =>
      this.monitor.track('get', () => this.client.get(id))
    );
  }
}

Step 2: Error Boundary

// src/flexport/errors.ts
export class FlexportServiceError extends Error {
  constructor(
    message: string,
    public readonly code: string,
    public readonly retryable: boolean,
    public readonly originalError?: Error
  ) {
    super(message);
    this.name = 'Flexpor

                  Flexport SDK Patterns
Overview
Production-ready patterns for Flexport SDK usage in TypeScript and Python.
Prerequisites

Completed flexport-install-auth setup
Familiarity with async/await patterns
Understanding of error handling best practices

Instructions
Step 1: Implement Singleton Pattern (Recommended)

// src/flexport/client.ts
import { FlexportClient } from '@flexport/sdk';

let instance: FlexportClient | null = null;

export function getFlexportClient(): FlexportClient {
  if (!instance) {
    instance = new FlexportClient({
      apiKey: process.env.FLEXPORT_API_KEY!,
      // Additional options
    });
  }
  return instance;
}

Step 2: Add Error Handling Wrapper

import { FlexportError } from '@flexport/sdk';

async function safeFlexportCall<T>(
  operation: () => Promise<T>
): Promise<{ data: T | null; error: Error | null }> {
  try {
    const data = await operation();
    return { data, error: null };
  } catch (err) {
    if (err instanceof FlexportError) {
      console.error({
        code: err.code,
        message: err.message,
      });
    }
    return { data: null, error: err as Error };
  }
}

Step 3: Implement Retry Logic

async function withRetry<T>(
  operation: () => Promise<T>,
  maxRetries = 3,
  backoffMs = 1000
): Promise<T> {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      return await operation();
    } catch (err) {
      if (attempt === maxRetries) throw err;
      const delay = backoffMs * Math.pow(2, attempt - 1);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error('Unreachable');
}

Output

Type-safe client singleton
Robust error handling with structured logging
Automatic retry with exponential backoff
Runtime validation for API responses

  if (!clients.has(tenantId)) {
    const apiKey = getTenantApiKey(tenantId);
    clients.set(tenantId, new FlexportClient({ apiKey }));

                  Flexport Security Basics
Overview
Security best practices for Flexport API keys, tokens, and access control.
Prerequisites

Flexport SDK installed
Understanding of environment variables
Access to Flexport dashboard

Instructions
Step 1: Configure Environment Variables

# .env (NEVER commit to git)
FLEXPORT_API_KEY=sk_live_***
FLEXPORT_SECRET=***

# .gitignore
.env
.env.local
.env.*.local

Step 2: Implement Secret Rotation

# 1. Generate new key in Flexport dashboard
# 2. Update environment variable
export FLEXPORT_API_KEY="new_key_here"

# 3. Verify new key works
curl -H "Authorization: Bearer ${FLEXPORT_API_KEY}" \
  https://api.flexport.com/health

# 4. Revoke old key in dashboard

Step 3: Apply Least Privilege

    apiKey: process.env.FLEXPORT_READ_KEY,
  }),
  writer: new FlexportClient({
    apiKey: process.env.FLEXPORT_WRITE_KEY,
  }),
};

Webhook Signature Verification

import crypto from 'crypto';

function verifyWebhookSignature(
  payload: string, signature: string, secret: string
): boolean {
  const expected = crypto.createHmac('sha256', secret).update(payload).digest('hex');
  return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected));
}

Security Checklist

[ ] API keys in environment variables
[ ] .env files in .gitignore
[ ] Different keys for dev/staging/prod
[ ] Minimal scopes per environment

                  Flexport Webhooks & Events
Overview
Securely handle Flexport webhooks with signature validation and replay protection.
Prerequisites

Flexport webhook secret configured
HTTPS endpoint accessible from internet
Understanding of cryptographic signatures
Redis or database for idempotency (optional)

Webhook Endpoint Setup
Express.js

import express from 'express';
import crypto from 'crypto';

const app = express();

// IMPORTANT: Raw body needed for signature verification
app.post('/webhooks/flexport',
  express.raw({ type: 'application/json' }),
  async (req, res) => {
    const signature = req.headers['x-flexport-signature'] as string;
    const timestamp = req.headers['x-flexport-timestamp'] as string;

    if (!verifyFlexportSignature(req.body, signature, timestamp)) {
      return res.status(401).json({ error: 'Invalid signature' });
    }

    const event = JSON.parse(req.body.toString());
    await handleFlexportEvent(event);

    res.status(200).json({ received: true });
  }
);

Signature Verification

function verifyFlexportSignature(
  payload: Buffer,
  signature: string,
  timestamp: string
): boolean {
  const secret = process.env.FLEXPORT_WEBHOOK_SECRET!;

  // Reject old timestamps (replay attack protection)
  const timestampAge = Date.now() - parseInt(timestamp) * 1000;
  if (timestampAge > 300000) { // 5 minutes
    console.error('Webhook timestamp too old');
    return false;
  }

  // Compute expected signature
  const signedPayload = `${timestamp}.${payload.toString()}`;
  const expectedSignature = crypto
    .createHmac('sha256', secret)
    .update(signedPayload)
    .digest('hex');

  // Timing-safe comparison
  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expectedSignature)
  );
}

Event Handler Pattern

type FlexportEventType = 'resource.created' | 'resource.updated' | 'resource.deleted';

interface FlexportEvent {
  id: string;
  type: FlexportEventType;
  data: Record<string, any>;
  created: string;
}

const eventHandlers: Record<FlexportEventType, (data: any) => Promise<void>> = {
  'resource.created': async (data) => { /* handle */ },
  'resource.updated': async (data) => { /* handle */ },
  'resource.deleted': async (data) => { /* handle */ }
};

async function handleFlexportEvent(event: FlexportEvent): Promise<void> {
  const handler = eventHandlers[event.type];

  if (!handler) {
    console.log(`Unhandled event type: ${event.type}`);
    return;
  }

  try {
    await handler(event.data);
    console.log(`Processed ${event.type}: ${event.id}`);
  } catch (error) {
    console.error
