# Authentication

> This section explains what Giro's secret keys are and how to obtain them.

#### Giro Secret Key

Giro uses secret keys to authenticate all API requests. Without including the correct key in your request, Giro will return an error. The key must be valid to ensure successful communication with our APIs. Always append the secret key to your request headers using the "x-giro-key" field.

To obtain your secret key:

<Steps>
  <Step title="Log in to your Giro dashboard." />

  <Step title="Navigate to Settings, then go to the API Keys and Webhook URL tab." />

  <Step title="Click the reveal icon in the Secret Key section to view your Giro secret key." />

  <Step title="Optionally, update your webhook url in the same section. We send events to the provided webhook. Click the link below for more information.">
    [Events](/additional-reference/events#webhook-events)
  </Step>

  <Step title="Copy the revealed key and store it securely." />
</Steps>

Protect your keys to prevent unauthorized access. If compromised, regenerate them immediately.
