ElevenLabs Security Basics

Overview

Security best practices for ElevenLabs API key management, webhook HMAC signature verification, and protecting cloned voice data. ElevenLabs uses a single API key (xi-api-key) and HMAC webhook authentication.

Prerequisites

• ElevenLabs SDK installed
• Understanding of environment variables
• Access to ElevenLabs dashboard (Settings > API Keys)

Instructions

Step 1: API Key Management

# .env (NEVER commit to git)
ELEVENLABS_API_KEY=sk_your_key_here

# .gitignore — MUST include these
.env
.env.local
.env.*.local

Git pre-commit hook to prevent accidental key commits:

#!/bin/bash
# .git/hooks/pre-commit
if git diff --cached | grep -qE 'sk_[a-zA-Z0-9]{20,}'; then
  echo "ERROR: ElevenLabs API key detected in staged changes!"
  echo "Remove the key and use environment variables instead."
  exit 1
fi

Step 2: Environment-Specific Keys

// src/elevenlabs/config.ts
interface ElevenLabsSecurityConfig {
  apiKey: string;
  webhookSecret: string;
  environment: "development" | "staging" | "production";
}

export function getSecurityConfig(): ElevenLabsSecurityConfig {
  const env = (process.env. || )  [];

   apiKey = process..;
   (!apiKey) {
      ();
  }

  
   (env ===  && apiKey.()) {
    .();
  }

   {
    apiKey,
    : process.. || ,
    : env,
  };
}
