 Some advantages of creating an OData interface through an API provider are automatic creation of a Swagger UI and an openAPI specification. A Swagger UI is a web-based tool that allows you to interact with the OData service and test its functionality. An openAPI specification is a standard format for describing the OData service and its metadata, which can be used by other tools and applications. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

A Content Modifier is a step in an integration flow that allows you to modify the message header or body using expressions or constants. You can use a Content Modifier to delete namespaces from a message by using expressions that remove the namespace declarations or prefixes from the XML elements or attributes. For example, you can use the expression replace($body,"xmlns:ns[0-9]+=\"[^\"]+\"","") to remove all namespace declarations from the message body. An XSLT mapping is a step in an integration flow that allows you to transform the message body using an XSLT stylesheet. You can use an XSLT mapping to delete namespaces from a message by using XSLT instructions that strip or exclude the namespace information from the output XML document. For example, you can use the instruction  to exclude all namespace prefixes from the output document. References: Content Modifier | SAP Help Portal, XSLT Mapping | SAP Help Portal

An API proxy is an API that acts as a proxy for another API, which is usually the backend service that provides the actual functionality. An API proxy can be used to add security, monitoring, caching, transformation, and other features to the backend API. An API provider is a logical grouping of APIs that share a common connection to the backend service. An API provider can be used to discover and import APIs from the backend service into the API Management capability within SAP Integration Suite. The relationship between an API provider and an API proxy is that the API proxy uses the API provider as a source of information and configuration for accessing the backend service. The API proxy also provides a unique URL that can be used by clients to invoke the API without exposing the details of the backend service. References: SAP Integration Suite | SAP Community, Create an API Proxy | SAP Tutorials
