Working With APIs

Getting Started

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

Command Line API refers to the original RESTful API.  Recognisable both by the port used and URL paths commencing:  

  • /inv/ 

FileWave Anywhere API v2 refers to the newer web admin, FileWave Anywhere, API and recognisable by paths commencing:

  •  /api/

Purpose of an API

As described, APIs are designed to communicate with systems.  As such, FileWave may be leveraged by other systems, e.g. SCCM data engines, in-house databases, etc.  To maintain security, there must be an authentication method to allow such communication to take place.  The API provides this kind of ability to provide in-depth integration on an as-needed basis.

Basic, non-specific command line examples:

macOS shell

curl -s -H "Authorization: $auth" \
    https://$server_dns:20445/inv/api/v1/query_result/ \
    --data $query \
    -H "Content-Type: application/json"

Windows PowerShell

$header = @{Authorization=“$auth"}

Invoke-RestMethod -Method POST \ 
    -Headers $header \
    -ContentType application/json \
    -Uri https://$server_dns:20445/inv/api/v1/query_result/ \
    -Body $query

The macOS 'Authorization' or Window's 'Headers' make use of base64 tokens.  From the above code, $auth would need to be set as one of these tokens.

Each user generated will have their own unique base64 token automatically generated.  This token can be revoked and new tokens created.  Each user may have multiple tokens.

The Token is the Key

The token allows access to any API calls from anything that has access to the FileWave Server.  It should not be shared unnecessarily and otherwise should be kept secret.

Tokens may be viewed from FileWave Central App:

  • Assistants > Manage Administrators

Select a desired Administrator and choose the 'Application Tokens' tab.  The token value to copy is the 'Token (base64)'


Token value from above image:


When choosing accounts and tokens for API interaction, consider making dedicated users for the task(s) required.  Set the permissions of that user to limit their ability to the required task alone.  If the token is compromised, this will limit not only the scope of how that token could be used by an attacker, but when revoking and generating a new token, minimal impact would be experienced.

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

API Requests

Requests could be one of:

Command Type Description
GET Returns a resource value
PUT Replaces a resource
PATCH Updates a resource
POST Creates a resource
DELETE Removes a resource

Data sent with requests are in the form of a JSON, as are the responses from those requests.

JSON data is broken into keys/value pairs, where values could even be lists inside of lists.


Below examples are using a python tool to reformat the returned response.  Python must be installed to benefit from this. If not, remove the piped section of the command or instal Python.

For example, actioning a GET to list of all FileWave Server Inventory Queries, could return a JSON similar to the below:

List Existing Inventory Queries

1) Get all Queries

curl -s  -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" \ | python3 -mjson.tool

API Application 

Browser Extensions


Remember:  All URLs start with

Must include the authorization header

Below are the possible options:


URL Use Options
query Show all queries GET POST
query/# Show information on a single query

Where # is the query ID
query_group/ Show all query group GET POST
query_group/# Detail information on a single group

Where # is the group ID
query_result/# Show the results of one query

Where # is the query ID
query_count   POST
component Show all component options on your instance GET
field_type Show all fields on your instance GET
license_definition Show all query GET
license_definition/# Show information on a single license

Where # is the license ID
Custom Fields
custom_field/ Show all custom fields  
custom_field/get_association   POST
custom_field/set_association   POST
custom_field/upload   POST
custom_field/usages/<Field_Name> Where <Field_Name> is the Internal Name (E.G "battery_cycle_count") GET
custom_field/values/   POST
custom_field/edit/   POST


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. Leveraging URLs and authorisation token to return Query Results.


Even if the URL is typically a POST, it provides an output similar to the following


Using the curl command

Viewing all available queries (GET)

curl -s -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" \ \
  | python3 -mjson.tool

Posting a new query (POST)

curl -s -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" \
  --header "Content-Type: application/json" \
  -X POST \
  -d @<path/name of new query.json> \

Removing a query (DELETE)

curl -s -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" \
  -X DELETE<id#>

Self-Signed Certificates

Hopefully everyone is using official certificates. However, if the FileWave Server does have a self-signed certificate, the above commands should fail.  To ignore the warnings the following is required.


Add the -k option to the command.  E.g.

curl -s -k -H "Authorization: e2FjYzRkYmQzLTI3ZjYtNDEyMi1iMGVhLTI1YmY0OGNmYWM0NX0=" \ \
  | python3 -mjson.tool

PowerShell requires somewhat more code to ignore the warning.  Add the below to the beginning of any script calling an API to a server with a self-signed certificate:

# Required for self-signed certs only
function Ignore-SSLCertificates
    $Provider = New-Object Microsoft.CSharp.CSharpCodeProvider
    $Compiler = $Provider.CreateCompiler()
    $Params = New-Object System.CodeDom.Compiler.CompilerParameters
    $Params.GenerateExecutable = $false
    $Params.GenerateInMemory = $true
    $Params.IncludeDebugInformation = $false
    $Params.ReferencedAssemblies.Add("System.DLL") > $null
        namespace Local.ToolkitExtensions.Net.CertificatePolicy
            public class TrustAll : System.Net.ICertificatePolicy
                public bool CheckValidationResult(System.Net.ServicePoint sp,System.Security.Cryptography.X509Certificates.X509Certificate cert, System.Net.WebRequest req, int problem)
                    return true;
    ## We create an instance of TrustAll and attach it to the ServicePointManager
    $TrustAll = $TAAssembly.CreateInstance("Local.ToolkitExtensions.Net.CertificatePolicy.TrustAll")
    $AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
    [System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols
    [System.Net.ServicePointManager]::CertificatePolicy = $TrustAll


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 'view only' web page version of the inventory. People can enter the URL for the query, hit refresh as many times as they like and will always see 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 achieved.
