.SYNOPSIS
    Script Automation Monkey (SAMY) is a unified MSP assistant that automates onboarding, headless offboarding,
    Datto RMM deployments, and toolkit management through a local UI, HTTP endpoints, or direct PowerShell switches.

.DESCRIPTION
    Install-DattoRMM is the core helper that handles credential retrieval (webhook or direct), OAuth token management,
    site list fetching/persistence, registry variable pushes, agent downloads/installs, and optional installer archiving.
    The UI exposes all tasks as checkboxes with select-all helpers, and each action is wrapped in detailed logging plus
    HTTP responders so callers can see success or failure.$jsContent  = Get-RemoteText -Url $Script:SamyJsUrl


    Key features:
      - Credential retrieval - securely fetches ApiUrl, ApiKey, and ApiSecretKey from a webhook when requested.
      - OAuth management - automatically acquires and refreshes bearer tokens over TLS to talk to Datto.
      - Site list fetching - returns the list of RMM sites and validates OutputFile extensions (.csv/.json).
      - Site list persistence - saves fetched site lists to the requester's desktop as CSV or JSON.
      - Registry variable push - writes site-specific variables under HKLM:\Software\SVS\Deployment.
      - Agent download & install - pulls the Datto RMM agent, launches it, and optionally saves a copy to C:\Temp.
      - HTTP endpoints - /getpw and /installDattoRMM handle UI or API-triggered workflows with failure trapping.
      - Idempotent & WhatIf support - uses ShouldProcess/SupportsShouldProcess to protect installs.
      - Headless Offboard - runs every offboarding task serially just like "Select All" in the UI.

    Throughout, secrets are never written to logs or console, and all operations produce clear success/failure messages via Write-LogHybrid.


.PARAMETER UseWebhook
    Switch that forces credential retrieval from the webhook at WebhookUrl using WebhookPassword.
    When omitted, you must supply ApiUrl, ApiKey, and ApiSecretKey directly.

.PARAMETER WebhookPassword
    Password to authenticate to the credentials-fetch webhook.  Mandatory when -UseWebhook is set.

.PARAMETER WebhookUrl
    URL of the credentials webhook endpoint.  Defaults to $Global:DattoWebhookUrl.

.PARAMETER ApiUrl
    Direct Datto RMM API base URL (used if not fetching from webhook).

.PARAMETER ApiKey
    Direct Datto RMM API key (used if not fetching from webhook).

.PARAMETER ApiSecretKey
    Direct Datto RMM secret (used if not fetching from webhook).

.PARAMETER FetchSites
    Switch to fetch the list of RMM sites and skip all install or variable-push actions.

.PARAMETER SaveSitesList
    Switch to save the fetched site list to the desktop as a file named by OutputFile.
    Must be used together with -FetchSites.

.PARAMETER OutputFile
    Name of the file to write the site list to (must end in “.csv” or “.json”).
    Defaults to 'datto_sites.csv'.

.PARAMETER PushSiteVars
    Switch to fetch site-specific variables and write them under HKLM:\Software\SVS\Deployment.

.PARAMETER InstallRMM
    Switch to download and launch the Datto RMM agent installer for the specified site.

.PARAMETER SaveCopy
    Switch to save a copy of the downloaded Datto RMM installer into C:\Temp.

.PARAMETER Offboard
    Switch that runs every off-boarding task sequentially (same behavior as checking "Select All" on the Off-Boarding tab) without launching the web UI.

.PARAMETER SiteUID
    The unique identifier of the Datto RMM site.  Mandatory when performing install or variable-push.

.PARAMETER SiteName
    The friendly name of the Datto RMM site (used in logging).  Mandatory when performing install or variable-push.

    # Fallback logger used when the SVSMSP module (and its Write-Log) is not available.
    # Mirrors the behaviour of the toolkit Write-Log (v1.5), including:
    #   - Default EventLog: "SVSMSP Events" (out of Application log)
    #   - Default EventSource: "SVSMSP_Module"
    #   - Level-based Event IDs and console colors
    #   - Global in-memory log cache

        .SYNOPSIS
            Standardized logging utility with console/file output and Windows Event Log support,
            including one-time event source initialization and optional auto-elevated creation
            of a custom log/source. (Fallback implementation for ScriptAutomationMonkey.)

        .DESCRIPTION
            Mirrors the SVSMSP toolkit Write-Log so that Write-LogHybrid can safely fall back
            when the module isn't loaded.

 <#
.SYNOPSIS
    Installs/configures the Datto RMM agent, fetches site lists, and optionally saves the site list to disk.

.DESCRIPTION
    Centralizes Datto RMM operations in one function:
      - Fetch API credentials from a webhook (-UseWebhook)
      - Acquire OAuth token
      - Fetch site list (-FetchSites)
      - Save site list to Desktop as JSON or CSV (-FetchSites + -SaveSitesList)
      - Write site variables to registry (-PushSiteVars)
      - Download & launch the RMM agent installer (-InstallRMM)
      - Save a copy of the installer (-SaveCopy)

.PARAMETER UseWebhook
    Fetches ApiUrl, ApiKey, and ApiSecretKey from the webhook when used with WebhookPassword.

.PARAMETER WebhookPassword
    Password for authenticating to the credentials webhook.

.PARAMETER WebhookUrl
    URL of the credentials webhook. Defaults to $Global:DattoWebhookUrl.

.PARAMETER ApiUrl
    Direct Datto API endpoint URL (if not using webhook).

.PARAMETER ApiKey
    Direct Datto API key (if not using webhook).

.PARAMETER ApiSecretKey
    Direct Datto API secret (if not using webhook).

.PARAMETER FetchSites
    Fetches the list of sites and skips all install steps.

.PARAMETER SaveSitesList
    Saves the fetched site list to Desktop using OutputFile. Must be used with -FetchSites.

.PARAMETER OutputFile
    Filename for saving the site list (.json or .csv). Defaults to 'datto_sites.csv'.

.PARAMETER PushSiteVars
    Writes fetched site variables into HKLM:\Software\SVS\Deployment.

.PARAMETER InstallRMM
    Downloads and runs the Datto RMM agent installer.

.PARAMETER SaveCopy
    Saves a copy of the downloaded agent installer to C:\Temp.

.PARAMETER SiteUID
    Unique identifier of the Datto site (required for install and registry push).

.PARAMETER SiteName
    Friendly name of the Datto site (used for logging).

.EXAMPLE
    # Fetch and save site list via webhook
    Install-DattoRMM -UseWebhook -WebhookPassword 'Tndmeeisdwge!' -FetchSites -SaveSitesList -OutputFile 'sites.csv'

.EXAMPLE
    # Headless install with site variables
    Install-DattoRMM -ApiUrl 'https://api.example.com' -ApiKey 'KeyHere' -ApiSecretKey 'SecretHere' \
      -SiteUID 'site-123' -SiteName 'Acme Corp' -PushSiteVars -InstallRMM

.EXAMPLE
    # Download and save installer to C:\Temp without installing
    Install-DattoRMM -ApiUrl 'https://api.example.com' -ApiKey 'KeyHere' -ApiSecretKey 'SecretHere' \
      -SiteUID 'site-123' -SiteName 'Acme Corp' -SaveCopy
