IT-Glue-API-PowerShell-Wrapper

This PowerShell module acts as a wrapper for the IT Glue API.

Introduction

IT Glue's API offers the ability to read, create, and update much of the data within IT Glue's documentation platform. That includes organizations, contacts, configuration items, and more. Full documentation for IT Glue's RESTful API can be found here.

This module serves to abstract away the details of interacting with IT Glue's API endpoints in such a way that is consistent with PowerShell nomenclature. This gives system administrators and PowerShell developers a convenient and familiar way of using IT Glue's API to create documentation scripts, automation, and integrations.

Function Naming

IT Glue features a REST API that makes use of common HTTP(s) GET, POST, PATCH, and DELETE actions. In order to maintain PowerShell best practices, only approved verbs are used. As such, the following mapping should be utilized:

GET -> Get-
POST -> New-
PATCH -> Set-
DELETE -> Remove-

Additionally, PowerShell's verb-noun nomenclature is respected. Each noun is prefixed with ITGlue in an attempt to prevent any naming problems.

For example, one might access the /users/ API endpoint by running the following PowerShell command with the appropriate parameters:

Get-ITGlueUsers

Installation

This module can be installed directly from the PowerShell Gallery with the following command:

Install-Module -Name ITGlueAPI

If running an older version of PowerShell, or if PowerShellGet is unavailable, one can manually download the Master branch and place the "ITGlueAPI" folder into the (default) C:\Program Files\WindowsPowerShell\Modules folder.

After installation (by either methods), load the module into your workspace:

Import-Module ITGlueAPI

Initial Setup

The first time you run this module, you will need to configure the base URI and API key that are used to talk with IT Glue. Doing so is as follows:

Run Add-ITGlueBaseURI. By default, IT Glue's api.itglue.com uri is entered. If you have your own API gateway or proxy, you may put in your own custom uri by specifiying the -base_uri parameter, as follows: Add-ITGlueBaseURI -base_uri http://myapi.gateway.example.com.
Run Add-ITGlueAPIKey. It will prompt you to enter your API key (please refer to IT Glue's documentation here for generating an API key).
[optional] If you would like the IT Glue module to remember your base uri and API key, you can run Export-ITGlueModuleSettings. This will create a config file at %UserProfile%\ITGlueAPI that securely holds this information. Next time you run Import-Module, this configuration will automatically be loaded.

⚠️ Exporting module settings encrypts your API key in a format that can only be unencrypted with your Windows account. It makes use of PowerShell's System.Security.SecureString type, which uses reversible encrypted tied to your principle. This means that you cannot copy your configuration file to another computer or user account and expect it to work.

⚠️ Exporting and importing module settings requires use of the ConvertTo-SecureString cmdlet, which is currently unavailable in Linux and Mac PowerShell core ports. Until PS Core 6.0.0 is available, this functionality only works on Windows.

Note, table entries with - indicate that the functionality is not supported by the IT Glue API.

Each Get- function will respond with the raw data that IT Glue's API provides. Usually, this data has at least three sub-sections:

data - The actual information requested (this is what most people care about)
links - Links to specific aspects of the data
meta - Information about the number of pages of results are available and other metadata.

Each resource allows filters and parameters to be used to specify the desired output from IT Glue's API. Check out the wiki article on Using Filters and Parameters.

A full list of functions can be retrieved by running Get-Command -Module ITGlueAPI. Help info and a list of parameters can be found by running Get-Help <command name>, such as:

Get-Help Get-ITGlueUsers
