How to install the accessibility widget using Google Tag Manager

Step 1: Register your site and obtain a token

If you are installing the plugin for the first time, register (opens in a new tab) using Google, Facebook, GitHub or your own e-mail address and password.

After creating an account, go to the “My sites” tab and click the “Add site” (opens in a new tab) button.

In the form for adding a new site, enter the addresses of the websites where you want to use the token. If your site runs on a domain such as example.com and also www.example.com, add both addresses. Read more about this in the documentation (opens in a new tab).

Finally, click “Save” and copy the generated token from the “Your token” field.
