Workday SOAP APIs (also known as Workday Web Services) serve as the foundation for enterprise-level, system-to-system integrations and large-scale data exchanges. They are suited for scheduled, batch-based processes, such as importing or exporting large volumes of worker records, financial transactions, or payroll information. Within Extend and Integration apps, developers can use Orchestration Builder to visually connect SOAP services with REST APIs, handling the complex XML payloads and transforming them into formats like JSON. This framework enables apps to retrieve background data and feed it directly into transactional workflows.
