🛠️ How is this done (5 simple steps!)?

This is achieved using the new Workflow Builder feature in Slack and External Services in Salesforce. Here are the steps in brief:

1. Using the Slack Workflow Builder, create and publish a Workflow that post messages into a Slack Channel and is triggered by a Webhook. Read for more info: https://slack.com/intl/en-in/help/articles/360035692513-Guide-to-Workflow-Builder.

2. Construct a Swagger Schema for the Webhook provided by Slack (in Step 1). Use the Template given below to get started.

3. Created a Named Credential in Salesforce with URL - https://hooks.slack.com. (No Auth)

4. Import the Swagger Schema constructed in Step 2 using External Services.

5. Create a Flow as shown below:

            }
          }
        ],
