Automating Slack Notifications from Salesforce Using OmniStudio

Problem Statement

At Astrea IT Services, our compact yet capable team of developers oversees multiple Salesforce applications listed on AppExchange. Managing several apps simultaneously makes it difficult to manually track each one for client-reported issues. This becomes especially critical when High Priority Cases are raised — any delay in response can lead to customer dissatisfaction or potential business loss.

Objective

Automatically send a message to a designated Slack channel whenever a High Priority Case is created in Salesforce — all achieved using OmniStudio’s Integration Procedures without writing any Apex code.

Key Goals:

Immediate alerting for faster response to critical issues
Elimination of manual monitoring for urgent cases
Seamless communication via Slack, where the support team is already active

Why Is This Important for Astrea IT Services?

Tools & Technologies Used

Slack Webhook Integration
Salesforce Named Credential
OmniStudio Integration Procedures
OmniScript (for manual testing or inputs)
HTTP Action with conditional logic

Implementation Steps

1. Slack Setup

Created a new Slack App
Enabled Incoming Webhooks
Added the webhook to a dedicated Slack channel (e.g., #case-alerts)
Generated the Webhook URL for external integrations

incoming webhooks

2. Salesforce Named Credential

Created a Named Credential: SlackWebhook
Set the endpoint:
https://hooks.slack.com/services/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
Authentication Type: None (as it’s a public webhook URL)

3. OmniStudio Integration Procedure

Procedure Name: Slack_Case_Alert_IP
Inputs: Case Subject, Case Number, Priority, Contact Name, and Description
Used a Conditional Block to check if Priority is 'High'
Constructed a JSON body for Slack message
Used HTTP Action to post data to Slack via the Named Credential

4. OmniScript UI

Built a form to enter Case details manually
Linked the Integration Procedure
Can be used for testing, training, or operational input

When I create a new Case through the OmniScript and the Case Priority is set to High, a message is automatically sent to Slack.

5. Trigger for Integration

The starting trigger is the creation of a new Case record in Salesforce with the Priority set to 'High'. This initiates the Integration Procedure that sends an alert to Slack.

Trigger for Integration

Example Slack Message Sent

High-Priority Case Alert!  
Subject: Portal Not Loading  
Case Number: 000234  
Customer: Shainki  
Description: User is not able to log in after password reset.

Outcomes

Support team receives Slack alerts in real time
No Apex or third-party middleware is required

Future Enhancements

Add Slack buttons for in-message actions like "Assign", "Acknowledge", or "Close"
Include Slack user mentions for escalation
Implement Slack-to-Salesforce updates for two-way communication
