F5 BIG-IP AS3 (Application Services 3 Extension)

AS3 is BIG-IP's declarative application-services API — one document describes tenants, applications, virtual servers, pools, monitors, profiles and WAF policies, and AS3 converges the device to it. 13 operations over /mgmt/shared/appsvcs. Two properties make it unusually good for automation: controls.dryRun runs the full validation chain without touching the device (and is wired to the delete path as well as create), and GET /declare?age=0-15 keeps a bounded history of prior declarations that can be re-deployed as an undo. The declaration body itself is governed by a separately published JSON Schema, not by this OpenAPI, and no operation in the contract declares an operationId.

F5 BIG-IP AS3 (Application Services 3 Extension) is one of 22 APIs that F5 publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Tagged areas include BIG-IP, Application, Load Balancing, Declarative, and Infrastructure-as-Code. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a changelog.

This API exposes 13 operations across 7 paths, organized into 4 resource areas, and defines 3 schemas. It is described by OpenAPI 3.0.0, at version 3.56.0.

Requests are made against a single base URL, /mgmt/shared/appsvcs.
