Step 1: Select a LeadPages page to update from your LeadPages dashboard and click Edit. (If your page is using the Standard Builder and not the Drag-and-Drop Builder, click here).
Step 2: In the LeadPages editor, click on the Widgets panel (located in the left sidebar) and find the HTML widget. Drag-and-drop this widget onto the desired location of your page.
Step 3: Click on the block that appears on your page and click the button HTML to open the text editor.
Step 4: In the text editor that opens, copy and paste your Interact iFrame embed code and click Save.
Step 5: Preview your LeadPages page and make sure your Interact app is embedded properly. You can always resize the embed by updating the Interact embed settings and repeating Step 4.
