RAML (RESTful API Modeling Language) and OpenAPI (formerly Swagger) are industry-standard, language-agnostic specification languages designed to describe RESTful APIs. They provide a structured, machine-readable format for defining API resources, methods, parameters, and response schemas. Within the SAP Integration Suite, the API Management capability explicitly supports the import of API definitions written in both OpenAPI and RAML formats to automatically generate API proxies. This allows for streamlined API design, documentation, and management.

B. CXML: This is a specific XML-based protocol for business-to-business e-commerce transactions, not a general-purpose language for describing the structure of an API.

D. HTML: This is the standard markup language for creating and structuring web pages for human display, not for defining a machine-readable API contract or specification.

SAP Integration Suite Documentation: In the section on API Management

the process for creating an API proxy is described. It states

"You can create an API proxy by importing an API specification file. The supported formats are OpenAPI (2.0 and 3.0) and RAML (0.8 and 1.0)."

2. OpenAPI Initiative Documentation: "The OpenAPI Specification (OAS) defines a standard

language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code

documentation

or through network traffic inspection."
