APIC-EM REST APIs
What is so great about REST?Easy to use: In mobile apps In console apps In web appsCisco APIC-EM REST APIs HostsDevicesUsers moreHow does this work?21
How does this work?Request3rd PartyAppResponseGet HostsList of Hosts3rd PartyApp
APIC-EM Example: Get HostApplication Policy Infrastructure Controller (APIC) Enterprise Module (EM)GET http://{APIC-EMController}/api/v1/hostRequest3rd PartyAppList of Hosts returned in JSONResponse23
Anatomy of a REST RequestMethod– GET, POST, PUT, DELETEURL– Example: on– Basic HTTP, OAuth, none, CustomCustom Headers– HTTP Headers– Example: Content-Type: application/jsonRequest Body– JSON or XML containing data needed to complete request24
And what is in the Response?HTTP Status Codes– http://www.w3.org/Protocols/HTTP/HTRESP.html– 200 OK– 201 Created– 500 Internal ErrorHeadersBody– JSON– XML25

Using Postman to get Network Hosts29
What about authentication? Basic HTTP: The username and password are passed to the server in anencoded string. OAuth: Open standard for HTTP authentication and session management.Creates an access token associated to a specific user that also specifies theuser rights. The token is used to identify the user and rights when making APIscalls in order to verify access and control. Token: A token is created and passed with each API call, but there is nosession management and tracking of clients which simplifies interactionbetween the server and client. APIC-EM uses Token for authentication management.30

APIC-EM Applications
APIC-EM ApplicationsPlug-and-Play (PnP)The APIC-EM Controller’s PnP (Plug and Play) application delivers on ZTD (ZeroTouch Deployment) for Cisco Enterprise Network routers, switches and wirelesscontrollers.Easy QoSThe APIC-EM Controller’s Easy Quality of Service application provides a simple wayto classify and assign application priority.Intelligent WAN (IWAN) ApplicationThe APIC-EM Controller's Intelligent WAN (IWAN) application automates theconfiguration of advanced IWAN features on Cisco 4000 Series Integrated ServiceRouters.Path TraceThe APIC-EM Controller’s Path Visualization application greatly eases andaccelerates the task of connection troubleshooting.33
