How do internal tools connect to other systems?

Internal tools connect to other systems through integrations, APIs, and database connections. The most common integrations include email for notifications and alerts, WhatsApp for customer communication, external REST APIs for pulling or pushing data, and direct database queries for real-time reporting. Modern internal tool platforms come with these integrations built in, so teams do not need to write custom middleware or maintain separate connector services. This means a single internal tool can pull order data from your database, send a WhatsApp message to a customer, trigger an email to your warehouse, and log everything to an external API, all without complex setup or developer intervention.
