Create and Manage API Keys

API keys are essential for authenticating your requests to any Telnyx API. This guide shows you how to create and manage your API keys through the Mission Control Portal.

1. In the Mission Control Portal, click on your name in the upper right corner, and click API Keys.
2. Click the Create API Key button.

3. In the Create API Key dialog, add a descriptive tag (e.g., "Voice API Development", "SMS Production", etc.) and choose your expiration settings.

4. Click Create.

Security Notice

We'll show the full API key value only once at creation. If you lose the key, you'll need to generate a new one.

We recommend using a secure password manager or secrets vault once you've created it. We're doing this to reduce the risk of accidental key leaks and help keep your account secure. This approach aligns with our best-in-class security standards and helps prevent accidental key exposures.

Best Practices:

• Never commit API keys to version control (Git, SVN, etc.).
• Use environment variables in your applications.
• Rotate keys regularly for production applications.
• Use separate keys for development and production.

Example of setting an environment variable:

export TELNYX_API_KEY="YOUR_API_KEY"

Once created, you can use your API key with any Telnyx service:

curl -X GET \
  --header "Authorization: Bearer YOUR_API_KEY" \
  "https://api.telnyx.com/v2/endpoint"

// Node.js
const telnyx = require('telnyx')('YOUR_API_KEY');

// Python
import telnyx
telnyx.api_key = "YOUR_API_KEY"

// Ruby
Telnyx.api_key = "YOUR_API_KEY"
