Hi Klaviyo,

I’m trying to setup a honeypot field using custom properties.

<form action="https://manage.kmail-lists.com/subscriptions/subscribe" method="POST">
  <!-- Hidden inputs for Klaviyo form settings -->
  <input type="hidden" name="g" value="YOUR_KLAVIYO_LIST_ID"> <!-- Klaviyo List ID -->
  <input type="hidden" name="l" value="1">
  <input type="hidden" name="boolean" value="true">

  <!-- Name input -->
  <label for="first_name">First Name</label>
  <input type="text" id="first_name" name="first_name" required>

  <!-- Email input -->
  <label for="email">Email</label>
  <input type="email" id="email" name="email" required>

  <!-- Honeypot field (hidden from users but sent as a custom property) -->
  <input type="text" name="propertiesihoneypot]" style="display:none;" value="">

  <!-- Submit button -->
  <button type="submit">Subscribe</button>
</form>

It doesn’t seem to capture the custom property using https://manage.kmail-lists.com/subscriptions/subscribe.

Do I need to setup the API with private keys to do so?

  // Send form data to Klaviyo to subscribe the user to a list
  const response = await fetch('https://a.klaviyo.com/api/v2/list/YOUR_LIST_ID/subscribe', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      api_key: 'YOUR_PRIVATE_API_KEY',
      profiles: i
        {
          email,
          $first_name: first_name,
          honeypot // Custom property sent to Klaviyo
        }
      ]
    })
  });

Thank you so much for your time.
