Administrative operations at the site or account level, such as creating or deleting members, adding products to your store, or managing orders for a site visitor, require an API key.
With a Wix API key, you can grant a custom set of permissions to a site or app for accessing or managing business data, including members, orders, products, events, bookings, and more.
You may want to use an API key in both Wix-managed and self-managed headless projects.
