RESTful API

The purpose of this guides is two fold:

First, to provide an introduction to those unfamiliar with using the FileWave API

Second, to be a reference for commands that can be used within the API


 

Getting Started

Purpose of an API

The RESTful API is code built into FileWave server (starting with version 6.x) providing the capability of two-way communication between the FileWave Postgres database and other external systems.  Using the calls in the RESTful API, a FileWave administrator can generate queries, exchange information, and more efficiently integrate inventory data. The RESTful API is designed so that queries and tools created using the current version API will continue to function as future versions of the FileWave server and admin apps are introduced.

Many institutions using FileWave for inventory management of their various computing devices also have existing databases for tracking systems. These DB’s could range from simple, in-house SQL databases designed to keep track of institutional assets to a full-blown, commercial data engine such as SCCM. The RESTful API contains the mechanisms to integrate those databases into FileWave through an authentication system, followed by a standardized set of queries using the JSON (JavaScript Object Notation - https://json.org) format.

Possible uses could be integrating existing SCCM data into FileWave queries; sending Fileset information from FileWave back to your help desk database, such as Invgate; or integrating purchase order system data into the application license data stored in FileWave.

The RESTful API provides you, the FileWave administrator, with the ability to expand the depth of information about your managed systems. Imagine being able to integrate years of detailed inventory stored in your site’s commercial database with the ease of the FileWave Admin’s Inventory queries, or being able to create a simple front end application that alerts you to sudden changes in the software licenses you have enabled across your entire company or campus. The RESTful API provides this kind of expansion of your ability to provide in-depth asset and license management on an as-needed basis.

The Token is the Key

For security reasons, we will need a token to access the RESTful API.  Before version 12.9 there was only one token for inventory (Admin Preferences → Inventory → "Shared Key") that had total read and write access to all data.  Starting in 12.9 there can be many application tokens, each with their own rights. 

For more information on the Application Tokens see the Manual page: Managing FileWave Administrators (Application Tokens)

We will need the base64 version of the token for the rest of the activity.

Breaking down the JSON/Results

When you send (AKA POST) or receive (AKA GET) inventory information it will be sent/received in the form of JSON.

JSON is broken into keys and values. One key benefit of JSON over CSV is the ability to do lists inside of lists.

For example, doing a GET to look at a list of all the inventory queries in your server, and then the results of one of those queries would look like this:

GET all queries

Examples

Using a browser extension

Using Mod-Header (see tools section), you can make Chrome a RESTful API browser by taking advantage of the FileWave Django Framework. Allowing you to look at the URLs and how things show up by telling the browser to send a token as an "Authorization" header each place you go to.


Even if you go to a url that is typically a POST url, it provides a box below you can post with


Using the curl command

Viewing all available queries (GET)

curl -s -k -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" https://myserver.company.org:20445/inv/api/v1/query/ | python -mjson.tool

Posting a new query (POST)

curl -s -k -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" --header "Content-Type: application/json" -X POST -d @<path/name of new query.json> https://myserver.company.org:20445/inv/api/v1/query/



Removing a query (DELETE)

curl -s -k -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" -X DELETE https://myserver.company.org:20445/inv/api/v1/query/<id#>


Using PHP

Saved as a php file (like inv.php), update the url and auth code, then place the file on a web server where PHP has been enabled. This creates a webpage that is a view only version of your inventory. People can go to the URL for the query and hit refresh as many times as they like, always seeing the latest information in inventory All without having to hassle IT for the latest data.

The output of the query results isn't fancy, but this is to illustrate what can be done.
