Based on what the postman does, what the codegen does, I believe it is possible, from an api specification, to perform an automatic integration of an X system with a Y system.
Imagine a virtual store, which needs to calculate freight, track objects on carriers, make payments, issue invoices, send data to price comparators, and more. All this via external systems. If there is a similar system to postman and swagger codegen, we could just import the API specification (in swagger, postman, raml ...) and at most do data transformation, point to the source of the data that should be sent in the API and ready, integration would be done.
Does anyone know something like this or next to it?
