XML API Gateway

Every API Gateway can transport XML messages. The question is does the gateway understand XML and does it offer XML related functions that help to route, integrate and secure API traffic? XML is often considered legacy technology but there are still today application where XML is the best choice. For API JSON is mostly the simpler and better choice. But either you have to integrate old legacy XML services or you need to support standardized XML formats in new projects an API Gateway that supports XML technologies can be valueable.
