What does a Slack integration do?

A Slack integration is designed to connect third-party applications to the Slack platform, enabling a seamless flow of information and functionality between the apps. This connection allows users to receive notifications, update tasks, or access data directly within Slack, enhancing productivity and collaboration. Integrations can automate workflows, streamline processes, and bring relevant external content into the Slack workspace, making it a powerful tool for teams that rely on various applications for their daily operations.
