Cisco APIC REST API
The Application Policy Infrastructure Controller REST API is the single programmatic interface into the ACI Management Information Tree. GET, POST and DELETE against /api/mo/.json (managed-object addressing) or /api/class/.json (class queries) read and write policy — tenants, application profiles, EPGs, bridge domains, VRFs, contracts, filters, L3Outs — plus statistics, faults and audit records. Query scoping, filtering, ordering and pagination are expressed as URI parameters (query-target, target-subtree-class, rsp-subtree, order-by, page, page-size). The same endpoints support ?subscription=yes to open a WebSocket push-notification channel.
