Here you’ll find instructions for how to connect the ActiveCampaign API key to the Nimble website, and then how to connect the popup form we’ll use for each lead magnet (see here for the 4 lead magnets) to its respective ActiveCampaign funnel.
Each subscription form is in a popup. You’ll find them, from the WP Sidebar, under Templates > Popups. Then hover over the name of each Popup and click “Edit with Elementor” (open it in a new tab), and that will take you to the page where you’ll be able to edit that subscription form’s settings per the instructions at the link above.
