What Are API & System Integration Services?

API and system integration services connect different software applications and systems so they can exchange data and work together. An API acts as a communication layer between applications, while system integration combines multiple applications, platforms, services, or business workflows into a connected technology ecosystem.

For example, a business may connect its website with a CRM, payment gateway, ERP, communication platform, mobile application, analytics system, or external SaaS platform through APIs and integration workflows.
