Send Slack Notifications From Marketing Cloud

You can use Slack Incoming Webhooks into a script automation, a landing page or email to send a notification to one of your Slack channel.

For example, setting reminders addressed to MC users or send a notification with a data extension records counts...

Steps:

Setup Slack's Incoming Webhooks
Setup an AMPscript block
Setup a script automation (if not using it from email or landing page)

Setup Slack's Incoming Webhooks

You can refere to Slack's Incoming Webhooks documentation. You will need to:

Create a Slack app
Enable Incoming Webhooks if you already have an app, you can edit your apps page directly
Create an Incoming Webhook

💡 you can use one of the nice SLDS icons to make to app friendly with Einstein for instance

Setup an AMPscript block

The AMPscript code block can be used in : an email, a landing page, then a script activity. In this example, we will use it into a script activity, but this would work with the other versions. We will use the TreatAsContent and HTTPPost2 functions.

SIMPLE EXAMPLE

%%[
set @url = "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"
/* "mrkdwn" parameter enables the slack markdown option */
set @contentLoad1 = '{"attachments": [{"title": "Msg title :smiley code:","mrkdwn": true,"text": "'
set @slackMsg = '*Bold Text*
- Some text here: %%=DataExtensionRowCount("MyDe")=%%

*OTHER BOLD TEXT*
- Some other text here: %%=DataExtensionRowCount("MyDe2")=%%'
/* "Color" of the attachment line*/
set @contentLoad2 = '","color": "#7CD197"}]}'
/* prepare the payload for the HTTPPOST */
set @contentLoad = TreatAsContent(concat(@contentLoad1,@slackMsg,@contentLoad2))
var @statusCode
var @response
  /* Posts the message*/
set @post = HTTPPost2(@url,"application/json", @contentLoad, false,@statusCode, @response)
]%%

You can insert mpre personalisation thanks to AMPscript functions or add dyn images or formatted contents.

EXAMPLE WITH ATTACHED IMAGE

%%[
set @url = "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"
set @contentLoad1 = '{"attachments": [{"title": "CONTACT DELETION REMINDER :warning:","mrkdwn": true,"text": "'
set @slackMsg = 'Reminder - Today we have *%%=DataExtensionRowCount("DeleteDE")=%%* extra contacts to delete !
1. Go to Contact Builder in All Contacts
2. Click on `delete` from data extension
3. Select the data extension from `Data Extensions > path > path`
4. Click On delete contacts'
set @contentLoad2 = '","color": "#d91e18", "image_url": "https://www.fillmurray.com/460/300"}]}'
set @contentLoad = TreatAsContent(concat(@contentLoad1,@slackMsg,@contentLoad2))
var @statusCode
var @response
set @post = HTTPPost2(@url,"application/json", @contentLoad, false,@statusCode, @response)
]%%

💡 Choose what you prefer and style your message thanks to Slack formating documentation and use the Message Builder to prepare your JSON

Setup a script automation

First save the AMPscript above into a content builder HTML block
Create a Script Activity into the *Automation Studio

Call the AMPscript block into your SSJS script

<script runat="server">
Platform.Load("Core", "1.1.1");
try {
    var ampscriptCode = Platform.Function.ContentBlockByID("ContentBlockByID");
    var textBlock = TreatAsContent(ampscriptCode);
} catch (ex) {
    Write("error message: " + ex);
}
</script>
