.SYNOPSIS
Call a method in the Safeguard SPS Web API.
 
.DESCRIPTION
This utility is useful for calling the Safeguard SPS Web API for testing or
scripting purposes. It provides a couple benefits over using curl.exe or
Invoke-RestMethod by generating or reusing a secure session and composing
the Url, headers, parameters, and body for the request.
 
This script is meant to be used with the Connect-SafeguardSps cmdlet which
will generate and store a variable in the session so that it doesn't need
to be passed to each call to the API. Call Disconnect-SafeguardSps when
finished.
 
Safeguard SPS Web API is implemented as HATEOAS. To get started crawling
through the API, call Show-SafeguardSpsEndpoint. Then, you can follow to
the different API areas, such as configuration or health-status.
 
.PARAMETER Appliance
IP address or hostname of a Safeguard appliance.
 
.PARAMETER Method
HTTP method verb you would like to use: GET, PUT, POST, DELETE.
 
.PARAMETER RelativeUrl
Relative portion of the Url you would like to call starting after /api.
 
.PARAMETER Accept
Specify the Accept header (default: application/json), Use text/csv to request CSV output.
 
.PARAMETER ContentType
Specify the Content-type header (default: application/json).
 
.PARAMETER Body
A hash table containing an object to PUT or POST to the Url.
 
.PARAMETER JsonBody
A pre-formatted JSON string to PUT or Post to the URl. If -Body is also specified, this is ignored.
It can sometimes be difficult to get arrays of objects to behave properly with hashtables in Powershell.
 
.PARAMETER Parameters
A hash table containing the HTTP query parameters to add to the Url.
 
.PARAMETER JsonOutput
A switch to return data as pretty JSON string.
 
.PARAMETER BodyOutput
A switch to just return the body as a PowerShell object.
 
.INPUTS
None.
 
.OUTPUTS
JSON response from Safeguard Web API.
 
.EXAMPLE
Invoke-SafeguardSpsMethod GET starling/join
 
.EXAMPLE
Invoke-SafeguardSpsMethod GET / -JsonOutput
 
.EXAMPLE
Open-SafeguardSpsTransaction

$body.admin_address = "admin@mycompany.corp"
Invoke-SafeguardSpsMethod PUT configuration/management/email -Body $body

.SYNOPSIS
Open a transaction for making changes via the Safeguard SPS Web API.
 
.DESCRIPTION
This cmdlet is used to create a transaction necessary to make changes via
the Safeguard SPS API. Recent versions of SPS will open a transaction
automatically, but this cmdlet may be used to open a transaction explicitly.
 
In order to permanently save changes made via the Safeguard SPS API, you
must also call Close-SafeguardSpsTransaction or its alias
Save-SafeguardSpsTransaction. Clear-SafeguardSpsTransaction can be used to
cancel changes.
 
.INPUTS
None.
 
.OUTPUTS
JSON response from Safeguard Web API.
 
.EXAMPLE
Open-SafeguardSpsTransaction
$body = (Invoke-SafeguardSpsMethod GET configuration/management/email -BodyOutput)
$body.admin_address = "admin@mycompany.corp"
Invoke-SafeguardSpsMethod PUT configuration/management/email -Body $body

.SYNOPSIS
Close a transaction and save changes made via the Safeguard SPS Web API.
 
.DESCRIPTION
This cmdlet is used to end a transaction and permanently save the changes
made via the Safeguard SPS API. This cmdlet is meant to be used with
Open-SafeguardSpsTransaction. Save-SafeguardSpsTransaction is an alias
for this cmdlet. Clear-SafeguardSpsTransaction can be used to cancel changes.
 
To see the status of a transaction, use Get-SafeguardSpsTransaction. To
see only the changes that are about to be made via a transaction, use
Show-SafeguardSpsTransactionChange.
 
.INPUTS
None.
 
.OUTPUTS
JSON response from Safeguard Web API.

.SYNOPSIS
Get the status of a transaction using the Safeguard SPS Web API.
 
.DESCRIPTION
This cmdlet will report the status of an SPS transaction. The status 'closed'
means no transaction is pending. The status 'open' means the transaction is
pending. Close-SafeguardSpsTransaction can be used to permanently save changes.
Clear-SafeguardSpsTransaction can be used to cancel changes. The remaining
seconds is the time before the transaction will cancel automatically and the
login session will be terminated.
 
.INPUTS
None.
