Perplexity Security Basics

Overview

Security best practices for Perplexity API keys, tokens, and access control.

Prerequisites

  • •Perplexity SDK installed
  • •Understanding of environment variables
  • •Access to Perplexity dashboard

Instructions

Step 1: Configure Environment Variables

bash
# .env (NEVER commit to git)
PERPLEXITY_API_KEY=sk_live_***
PERPLEXITY_SECRET=***

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

Step 2: Implement Secret Rotation

bash
# 1. Generate new key in Perplexity dashboard
# 2. Update environment variable
export PERPLEXITY_API_KEY="new_key_here"

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

# 4. Revoke old key in dashboard

Step 3: Apply Least Privilege

EnvironmentRecommended Scopes
Developmentread:*
Stagingread:*, write:limited
ProductionOnly required scopes

Output

  • •Secure API key storage
  • •Environment-specific access controls
  • •Audit logging enabled

Examples

Service Account Pattern

typescript
const clients = {
  reader: new PerplexityClient({
    apiKey: process.env.PERPLEXITY_READ_KEY,
  }),
  writer: new PerplexityClient({
    apiKey: process.env.PERPLEXITY_WRITE_KEY,
  }),
};

Webhook Signature Verification

typescript
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
  • • Webhook signatures validated
  • • Audit logging enabled

Audit Logging

typescript
interface AuditEntry {
  timestamp: Date;
  action: string;
  userId: string;
  resource: string;
  result: 'success' | 'failure';
  metadata?: Record<string, any>;
}

async function auditLog(entry: Omit<AuditEntry, 'timestamp'>): Promise<void> {
  const log: AuditEntry = { ...entry, timestamp: new Date() };

  // Log to Perplexity analytics
  await perplexityClient.track('audit', log);

  // Also log locally for compliance
  console.log('[AUDIT]', JSON.stringify(log));
}

// Usage
await auditLog({
  action: 'perplexity.api.call',
  userId: currentUser.id,
  resource: '/v1/resource',
  result: 'success',
});
