First, from the GreenLeaze dashboard, create a new integration.
Click on “Connexion logiciel externe” in the left menu, then select “WooCommerce.”

Here you will need to provide the following information:

Your shop URL (e.g., example.com) without the https:// prefix;
The API URL of your shop using the following format (with the https this time):
https://your-shop.com/wp-json/wc/v3;
An email address so the GreenLeaze technical team can contact you if needed;
The API keys of your WooCommerce shop (see documentation).
