I came across the Gravitee API Manager, in their documentation they mention converting SOAP to REST and vice versa. I am working with legacy systems and I only need pure SOAP integrations. So my question is, does Gravitee support pure SOAP API integrations?
You can use gravitee just as a gateway to relay SOAP calls to your backend without transformation (It is not the main purpose of Gravitee but it works fine). Or you can use the "Rest to SOAP transformer" policy, so the WS clients will be able to call it with REST calls which will be transformed to SOAP calls to your backend by the gateway component.
