I am new to Mule and learning. I downloaded Anypoint Studio and successfully developed and deployed 3 stand alone system APIs to cloud hub. They work via Postman.
Now I want to create a 4th API which is a Process API which will call these 3 system APIs in order. My understanding of API-Led Connectivity is like APIs calling APIs for re-usability.
So I went to the palette and downloaded my 3 published APIs from the Exchange. I dragged and dropped the first one. It asked me to configure. When I provide the values it's failing. That API works fine when I test it via Postman. What mistake am I doing here?
