SOAP API 

Part of the CloudQix Glossary of API & Integration Terms 

Definition 

A SOAP API (Simple Object Access Protocol API) is a messaging protocol that allows applications to exchange structured data using XML. 

In-Depth Explanation 

Before REST became the dominant standard, SOAP APIs were widely used for integrations. They are more rigid and complex, requiring XML formatting and strict rules for requests and responses. While older, SOAP APIs are still common in legacy financial, government, and enterprise systems. 
 
CloudQix supports SOAP APIs so businesses can integrate legacy systems alongside modern REST-based apps. 

Examples by Industry 

• Finance: A SOAP API processes secure financial transactions between banks. 

• Software: Enterprise software may expose SOAP APIs for system-to-system communication. 

• Retail: Older ERP systems often rely on SOAP APIs for inventory updates. 

• Transportation & Logistics: SOAP APIs connect legacy warehouse management systems to modern logistics tools. 

Why It Matters 

SOAP APIs are important because they still power many legacy systems. Supporting SOAP ensures businesses can integrate old and new technologies together.
