# Send Slack Message

{% hint style="info" %}
The Gradient Works Slack app must be [installed in your workspace](/kb/integrations/slack.md) to use this action. This action runs asynchronously and does not have any result outputs.
{% endhint %}

The message body supports @ mentioning other users in a couple of ways:

1. Using a Salesforce User record or Id (The User's email must match in Salesforce and Slack)
2. Slack display name

Need to show additional record information at a glance?

Use the "Fields to Display" section of the action editor to customize what information we include about Salesforce records in the Slack message.

To add a link to a record in the Slack message, add a record in the "Linked Records" section. We'll include a "View in Salesforce" button in the Slack message.

## Configuration

{% tabs %}
{% tab title="Flow Element" %}

{% endtab %}

{% tab title="Apex Properties" %}
Please note that you will not directly interact with these input fields as you do with some Flow Actions. Instead the Gradient Works custom editor takes care of the heavy lifting.
