Microsoft Azure Functions
Azure Functions is a serverless compute platform from Microsoft Azure enabling event-driven code execution triggered by HTTP requests, timers, queues, blobs, and other Azure services. The Azure Functions management API provides programmatic access to function app lifecycle management, deployment, configuration, scaling, and monitoring through Azure Resource Manager.

Create a Function in a Function App and Verify It
Create a single function inside an existing function app, then read it back to confirm it exists.
ARAZZODeploy a Function and Sync Its Triggers
Create a function, sync the function app's triggers, and list the resulting trigger status.
ARAZZOInspect a Function App and Issue an Admin Token
Read a function app, list its functions, and issue a Functions admin token for the runtime API.
ARAZZOProvision an Azure Function App and Confirm It Is Running
Create a function app, poll until it reports a running state, then list its functions.
ARAZZOProvision a Staging Deployment Slot
Create a deployment slot on a function app, poll it until running, and ensure it is started.
ARAZZORecord a Deployment and Verify the Deployment Log
Create a deployment record on a function app, read it back, and list all deployments.
ARAZZORotate a Function Key and Confirm It
Create or update a named function key, then list the function keys to confirm the new value is in place.
ARAZZORotate a Host-Level Key and List All Host Keys
Create or update a host key (function or system) of a function app, then list all host keys to confirm.
ARAZZOPreview and Swap a Slot Into Production
Diff a staging slot against a target, swap it in, and confirm the app is running.
ARAZZOUpdate Function App Settings and Confirm Them
Read the current app settings, write a merged set, and list them back to confirm.
ARAZZOUpdate Function App Site Configuration and Restart
Read the web site configuration, apply changes, then restart the app to pick them up.
