When to use this.

The "List Leads by Campaign ID (Smartlead)" action allows users to efficiently retrieve all leads associated with a specific campaign ID within the Smartlead platform. Key input parameters include "campaign_id," which is essential for identifying the campaign, and optional filters such as "status" to narrow down leads by their current status, and "limit" to control the number of leads returned. The output includes a comprehensive set of data fields such as lead IDs, first and last names, emails, phone numbers, company names, LinkedIn profiles, lead statuses, and more, providing a detailed overview of each lead's information. This action is particularly useful for marketing teams and sales professionals looking to analyze campaign performance, manage lead follow-ups, and enhance targeted outreach efforts. As part of the integration category, it streamlines lead management processes and supports data-driven decision-making.
