API capability pack for bounded Zuora Billing v1 revenue operations. Enroll a Zuora OAuth2 bearer connection named zuora with base_url set to the tenant REST endpoint, for example https://rest.zuora.com, https://rest.na.zuora.com, or a documented sandbox endpoint. The pack reads accounts, account summaries, account subscriptions, subscriptions, invoices, product catalog, orders, product charge definitions, and bill runs through documented Zuora REST endpoints. Bundled recipes provide a scheduled revenue operations digest, an account revenue brief, a catalog readiness brief, and guarded account intake. Writes are approval-gated and limited to creating one account without payment methods or subscriptions. Subscription/order/invoice mutation, payment-method creation or authorization, bill-run creation/post/cancel/delete, invoice post/reverse/write-off/collection/delete, order activation/cancel/delete, OAuth token exchange, object CRUD, exports, files, webhooks, custom object mutation, and arbitrary Zuora API passthrough are intentionally not exposed. No credential is embedded in the manifest.
