The.com BasicsCommunity's Web App
You can add a Community sign-in unit to your site via embed code.
The first thing you'll need to do is create and configure the sign-up unit from within the Community web app.
Go to Settings > Integrations.
Customize the popup forms look, then click Continue.
Customize the sign-up experience with Send Additional Confirmation (optional). Note: this is where online stores can place discount codes. The Additional Confirmation message will automatically be sent after a new Member completes registration. When you're done, click Continue.
From "Behavior" you can configure your pop-up display (or not display) on certain URLs. Note: your Community Sign-Up Unit will only display for web visitors in US and Canada. When you're ready, click Save Changes.
From the "Installation Instructions," copy the required code snippet.
Installing the code snippet
In The.com editor:
Create a new Raw HTML element at the bottom of a page where you want to include the sign-up unit.
Paste the code in the Text attribute.
Deploy your page.
The popup won't work in the editor, so you'll need to deploy and view the live site to confirm that it is working. The popup will appear after the number of seconds specified when configuring its behavior in your Community account.
