Green Cart Carbon

Install Green Cart Checkout on WooCommerce

Green Cart Checkout adds a "Plant a tree" line to your checkout: the customer contributes €2.00 in one click, a tree is planted, and they receive their certificate by email.

Before you start

  • A WordPress site with the WooCommerce plugin installed and active.
  • Your Green Cart API key, in the form gcc_live_…, provided with your account.

This key is shown in clear only once: keep it somewhere safe. Lost it? Write to contact@greencartcheckout.com.

Installation in three steps

  1. Download the plugin: woocommerce-plugin.zip.
  2. Install it in WordPress: Plugins menu, "Add New Plugin", "Upload Plugin", pick the downloaded file, then click "Activate".
  3. Paste your API key: in the plugin settings (WooCommerce, Green Cart tab), paste the gcc_live_… key and save. The plugin checks the connection straight away and links your store: the "Plant a tree" line appears on your checkout page.

What happens on each order

What the contribution covers

Every order with a contribution funds the planting of one tree, tied to a partner reforestation project. The contribution also covers collection fees and the platform, invoiced monthly to the merchant: the breakdown is on the pricing page.
