I am implementing service in  APIC  which send a request through a RESTfull API a  containing both string data and binary (file as attachment) to the customer back-end service which is a SOAP-based WS. In my case API Connect is offering the RESTfull API end-point. Could you kindly share with me a little bit more information about how you manage to deal with?

Is a key point for our customer and unfortunately I didn't manage to find too much information.

Thanks in advance for your time and support.
