Mailchimp automations, customer journeys, templates and folders, file manager, landing pages, surveys, connected sites, conversations, exports, batches, batch webhooks, verified domains, authorized apps, and account metadata 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.
