.synopsis * Posts a message to a Microsoft Teams channel via webhook .description * Posts a message to a Microsoft Teams channel via webhook * Discord webhooks specify both the user posting it and the channel * Not sure of the max character limit, so truncating is disabled * Supports Text and Title via argument. Other Office 365 card attributes can be added via properties in a hash table passed through to the AdditionalProperties argument * See https://messagecardplayground.azurewebsites.net/ for the valid attributes, with examples * Selects the webhook to use in the following priority (first most preferred) order, with the aim of easiest use * Webhook argument passed to function * $TeamsWebhook * if none of the above, it errors. No prompting because of the automation focus .parameter Text * The text to display * Array, so works for array or single string * i.e. will send a table as easily as a line of text * Will concatenate array as new lines, not spaces .parameter Webhook * The Webhook URL of the channel to post to * To get this * right click on the channel and select 'connectors' * edit an existing webhook connector and get the url or * add a new 'webhook' connector them get the url .parameter AdditionalProperties * Construct a fancier card via additional options * See https://messagecardplayground.azurewebsites.net/ for the valid attributes, with examples .notes * TODO: * Implement AdditionalProperties * Author: Ben Renninson * Email: ben@goldensyrupgames.com * From: https://github.com/GSGBen/Posh-Notify #> function Notify-Teams { Param ( [Parameter(Position=0,Mandatory=$true,ValueFromPipeline=$true)][string[]]$Text, [Parameter(Position=1,Mandatory=$false)][string]$Title, [Parameter(Position=2,Mandatory=$false)][string]$Webhook, [Parameter(Position=3,Mandatory=$false)][System.Collections.IDictionary]$AdditionalProperties ) #Join each element that may be passed through in the pipeline Process{ #If passed through the pipeline, join to a single array $CombinedArray += $Text } #only send after joining End{ #Specified webhook or global or fail if ($Webhook) { $FinalWebhook = $Webhook } elseif ($TeamsWebhook) { $FinalWebhook = $TeamsWebhook } else { Write-Error "No webhook specified and `$TeamsWebhook not set!" return } #Join combined array into multi-line text.
