# AppFolio Security Basics
## Overview
AppFolio manages property portfolios containing tenant PII (SSNs, bank accounts, lease terms), owner financial data, and maintenance vendor records. A breach exposes rent rolls, payment histories, and personally identifiable tenant information across every managed property. Secure every integration point: API credentials, webhook endpoints, and any pipeline that touches tenant or owner financial records.
## API Key Management
```typescript
import https from "https";
import axios, { AxiosInstance } from "axios";
function createAppFolioClient(): AxiosInstance {
const clientId = process.env.APPFOLIO_CLIENT_ID;
const clientSecret = process.env.APPFOLIO_CLIENT_SECRET;
const baseUrl = process.env.APPFOLIO_BASE_URL;
if (!clientId || !clientSecret || !baseUrl) {
throw new Error("Missing APPFOLIO_CLIENT_ID, APPFOLIO_CLIENT_SECRET, or APPFOLIO_BASE_URL");
}
return axios.create({
baseURL: baseUrl,
auth: { username: clientId, password: clientSecret },
httpsAgent: new https.Agent({ minVersion: "TLSv1.2", rejectUnauthorized: true }),
});
}
```
## Webhook Signature Verification
```typescript
import crypto from "crypto";
function verifyAppFolioWebhook(req: Request, res: Response, next: NextFunction): void {
const signature = req.headers["x-appfolio-signature"] as string;
const secret = process.env.APPFOLIO_WEBHOOK_SECRET!;
const expected = 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 TenantSchema = z.object({
tenant_id: z.string().uuid(),
first_name: z.string().min(1).max(100),
last_name: z.string().min(1).max(100),
email: z.string().email(),
unit_id: z.string().uuid(),
lease_start: z.string().regex(/^\d{4}-\d{2}-\d{2}$/),
rent_amount: z.number().positive().max(100000),
});
function validateTenantPayload(data: unknown) {
return TenantSchema.parse(data);
}
```
## Data Protection
```typescript
const APPFOLIO_PII_FIELDS = ["ssn", "bank_account", "routing_number", "date_of_birth", "drivers_license"];
function redactAppFolioLog(record: Record<string, unknown>): Record<string, unknown> {
const redacted = { ...record };
for (const field of APPFOLIO_PII_FIELDS) {
if (field in redacted) redacted[field] = "[REDACTED]";
}
return redacted;
}
```
## Security Checklist
- [ ] API credentials stored in secrets manager, not `.env` in production
- [ ] HTTPS enforced with TLS 1.2+ for all API calls
- [ ] Tenant SSN and bank account numbers never logged
- [ ] Webhook signatures verified on every inbound request
- [ ] API credentials rotated quarterly
- [ ] Access scoped to minimum required property endpoints
- [ ] Rent payment data encrypted at rest
- [ ] Audit trail enabled for tenant record access
## Error Handling
| Vulnerability | Risk | Mitigation |
|---|---|---|
| Leaked API credentials | Full property portfolio exposure | Secrets manager + rotation |
| Unvalidated webhook payloads | Spoofed tenant updates | HMAC signature verification |
| Tenant PII in logs | Compliance violation (state privacy laws) | Field-level redaction |
| Overly broad API scope | Lateral access to unrelated properties | Per-property credential scoping |
| Unencrypted payment data | Financial data breach | TLS 1.2+ in transit, AES at rest |
