Install ASDK on Wix

Add the ASDK widget to a Wix site with Custom Code on all pages at the end of the body. Wix runs custom code only on published sites with a domain.

On this page

Wix adds third-party code through Custom Code in your site's settings.

Add the snippet

Open Custom Code

In your site's dashboard, go to Settings. Under Development & integrations, click Custom Code.

Add the snippet

Click + Add Custom Code at the top right and paste your snippet from the dashboard's Install page:

HTML

<script async src="https://cdn.asdk.com/v1/asdk.js" data-site-id="SITE_ID"></script>

Name it "ASDK" so you can find it later.

Choose where it runs

Under Add Code to Pages, choose All pages and Load code once. The widget follows page changes on its own, so it doesn't need to load again on every page.

Under Place Code in, choose Body – end. Click Apply.

Check

Open your published site (not the Editor), look for the chat button, then click Check installation on the dashboard.

If you later connect a different domain, Wix removes your custom code snippets: add the snippet again and check the installation.
