Mailchimp ecommerce carts, cart lines, customers, orders, order lines, products, variants, images, promo rules, promo codes, and store operations not retained in the compatibility core. Generated from the hash-anchored official Mailchimp Marketing API 3.0.91 Swagger. The us1 base is only an enrollment default; the connection base_url must use the account data-center prefix. Reads are grant-controlled and approval-free. Mutations are grant-off and approval-gated; destructive and administrative operations require approval every run.
