Embed an AI form on any WordPress page in 2 minutes

WordPress powers over 40% of the web, and Sift fits into any WordPress workflow. Whether you use the block editor, classic editor, or a page builder like Elementor, embedding the Sift widget is a one-step process.

Before you start: grab your Form ID and public API key from your dashboard. You will replace YOUR_FORM_ID and YOUR_PUBLIC_KEY in the snippets below.

Install Sift on WordPress

  1. 1

    Open the page or post in the editor

    From your WordPress admin, edit the page or post where you want the widget to appear. Both Gutenberg and the classic editor work.

  2. 2

    Add a Custom HTML block

    In Gutenberg, click the + button and search for Custom HTML. In the classic editor, switch to the Text tab. In Elementor, drag in an HTML widget.

  3. 3

    Paste the snippet and publish

    Paste the Sift embed code into the HTML block, replace the placeholders with your dashboard values, then publish or update the page.

html
<script
  src="https://siftforms.com/widget/v1.js"
  data-schema-id="YOUR_FORM_ID"
  data-api-key="YOUR_PUBLIC_KEY"
  async
></script>

Alternative install methods

Site-wide via header/footer plugin

Install a plugin like "Insert Headers and Footers" or "WPCode" and paste the snippet into the footer section. The widget will be available on every page (you control where it renders by adding it as a shortcode or block).

Direct theme edit (footer.php)

If you are comfortable editing theme files, paste the snippet into your child theme's footer.php just before the closing </body> tag. Always use a child theme to avoid losing changes on theme updates.

Tips for the best results

  • Use WordPress page builders like Elementor or Beaver Builder by dragging in an HTML widget
  • For multi-language sites with WPML, embed the same widget on translated pages — Sift handles input in any language
  • Use Sift webhooks to push extracted form data into WP Users, custom post types, or WooCommerce orders
  • Combine with Contact Form 7 by replacing the contact form entirely — Sift's free-text approach has higher completion rates

Troubleshooting

Widget code shows as plain text on the published page

You probably pasted into the Visual editor instead of the Text/HTML editor. In Gutenberg, use a Custom HTML block. In classic editor, switch to the Text tab before pasting.

Widget loads in preview but not on live site (cache)

Clear your WordPress caching plugin (WP Rocket, W3 Total Cache, etc.) and any CDN cache (Cloudflare, BunnyCDN). The widget script is fetched from siftforms.com so the script itself is not cached by your plugin.
