An NLog target for Slack - your logs in one place and instantly searchable, everywhere.


Note: it is no longer possible to pass in a custom channel, username or icon. This must be defined by your Slack App.


Via NuGet: Install-Package NLog.Slack

... or just build it your self!


  1. Create a new Slack App in the correct Workspace.
  2. Add the Incoming Webhooks functionality to your App.
  3. Generate a new Webhook URL and Authorize it to post to a channel.
  4. Copy your Webhook URL and configure NLog via your NLog.config file or programmatically, as below.


<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns=""

    <add assembly="NLog.Slack" />

  <targets async="true">
    <target xsi:type="Slack"

			<field name="Machine Name" layout="${machinename}" />
			<field name="Process Name" layout="${processname}" />
			<field name="Process PID" layout="${processid}" />

    <logger name="*" minlevel="Debug" writeTo="slackTarget" />

Note: it's recommended to set async="true" on targets so if the HTTP call to Slack fails or times out it doesn't slow down your application.


var config = new LoggingConfiguration();
var slackTarget = new SlackTarget
      Layout = "${message}",
      WebHookUrl = "",

config.AddTarget("slack", slackTarget);

var slackTargetRules = new LoggingRule("*", LogLevel.Debug, slackTarget);

LogManager.Configuration = config;

And you're good to go!
