Today, we released an update to the platform API. The recipe details endpoint(https://docs.workato.com/workato-api.html) returns a new field called version_author_name. This endpoint is available in the OEM API also.
You can implement single action patern (much like the Create record pattern in Saleforce connector) to avoid generating a large scaffolding code. This way the code generated will be smaller and easier to manage/debug etc.
