Prerequisites

Before you can execute the action Post on Slack, you must first enable incoming incoming webhooks on Slack and then copy the URL for incoming webhooks. For details, see https://api.slack.com/messaging/webhooks.

Workflow

To create an action in Lucidum, follow these steps:

1. Choose Action Center from the left pane.

2. In the Action Center, choose from the action types in the Channels pane.

3. To create a configuration for the action, click the Manage Configuration button. A configuration provides the connection and authorization information to communicate with the external solution.

4. Save the configuration.

5. To create an action, click the Create a new action button. An action specifies the task to execute, the data to include in the action, and how frequently to execute the action.

6. Save the action.

7. Lucidum automatically executes the action at the time and recurrence you defined in the action.

You can apply an existing configuration to more than one action. If a configuration already exists, you might be able to re-use the existing configuration and might not need to create a new one.
