OAuth 2.0 support was recently added to the API Editor and Code Generation engine. Now the support is added to Transformer as well as import/export in the Dashboard.
OAuth 2.0 is supported by various API description formats like RAML, Swagger, Google API, Mashery/IO Docs, etc. Our support for OAuth 2.0 was initially limited. However, we now fully support all grant types. Bring in your API description formats using OAuth 2.0 and import them on the Dashboard to make full use of our OAuth 2.0 feature or convert between different formats using the Transformer without losing OAuth 2.0 information. You can read up more details on our OAuth 2.0 feature at OAuth 2.0 Authorization.
