Application Integration supports Swagger files of the JSON format. It does not support other formats such as YAML.
Application Integration supports only single-document Swagger files. If you import a multi-document Swagger file, Application Integration does not load the dependencies.
If you create a service connector by importing a Swagger file that has a large number of complex types and operations, the service connector editor might be affected, because the generated service connector will be complex and bulky in size.

You can use a Swagger splitter tool to split the Swagger file. For more information, see the following community article:
