# Flexport Security Basics
## Overview
Flexport manages global freight logistics containing shipping manifests, customs declarations, commercial invoices, and supply chain partner data. A breach exposes trade routes, commodity values, importer/exporter identities, and customs brokerage details. Secure API credentials, webhook endpoints, and any pipeline that processes shipment tracking or purchase order data.
## API Key Management
```typescript
function createFlexportClient(): { apiKey: string; baseUrl: string } {
const apiKey = process.env.FLEXPORT_API_KEY;
if (!apiKey) {
throw new Error("Missing FLEXPORT_API_KEY — store in secrets manager, never in .env in production");
}
// Never log the key; log only a hash suffix for debugging
console.log("Flexport client initialized (key suffix:", apiKey.slice(-4), ")");
return { apiKey, baseUrl: "https://api.flexport.com/v2" };
}
```
## Webhook Signature Verification
```typescript
import crypto from "crypto";
import { Request, Response, NextFunction } from "express";
function verifyFlexportWebhook(req: Request, res: Response, next: NextFunction): void {
const signature = req.headers["x-hub-signature"] as string;
const secret = process.env.FLEXPORT_WEBHOOK_SECRET!;
const expected = "sha256=" + crypto.createHmac("sha256", secret).update(req.body).digest("hex");
if (!signature || !crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected))) {
res.status(401).send("Invalid signature");
return;
}
next();
}
```
## Input Validation
```typescript
import { z } from "zod";
const ShipmentQuerySchema = z.object({
shipment_id: z.string().regex(/^FLEX-\d+$/),
container_number: z.string().regex(/^[A-Z]{4}\d{7}$/).optional(),
origin_port: z.string().length(5).optional(),
destination_port: z.string().length(5).optional(),
hs_code: z.string().regex(/^\d{6,10}$/).optional(),
});
function validateShipmentQuery(data: unknown) {
return ShipmentQuerySchema.parse(data);
}
```
## Data Protection
```typescript
const FLEXPORT_SENSITIVE_FIELDS = ["customs_value", "commercial_invoice", "importer_tax_id", "broker_credentials", "hs_code"];
function redactFlexportLog(record: Record<string, unknown>): Record<string, unknown> {
const redacted = { ...record };
for (const field of FLEXPORT_SENSITIVE_FIELDS) {
if (field in redacted) redacted[field] = "[REDACTED]";
}
return redacted;
}
```
## Security Checklist
- [ ] API keys stored in secrets manager, `.env` files in `.gitignore`
- [ ] Webhook signatures verified on every inbound request
- [ ] Different keys for dev/staging/prod environments
- [ ] Key rotation scheduled quarterly with dual-key transition
- [ ] Git history scanned for leaked keys
- [ ] HTTPS enforced for all API calls
- [ ] Request/response logging redacts auth headers and customs values
- [ ] Least-privilege access: read-only tokens for dashboards, run tokens for operations
## Error Handling
| Vulnerability | Risk | Mitigation |
|---|---|---|
| Leaked API key | Full shipment and customs data exposure | Secrets manager + quarterly rotation |
| Unverified webhooks | Spoofed shipment status updates | HMAC-SHA256 signature verification |
| Customs data in logs | Trade compliance violation | Field-level redaction pipeline |
| Overly broad API scope | Access to unrelated shipment data | Role-scoped tokens per team |
| Unencrypted commercial invoices | Financial data breach | TLS 1.2+ in transit, AES at rest |
