Which tool can be used to configure APIs in MuleSoft?

The option that indicates the most appropriate tool for configuring APIs within MuleSoft is the Anypoint API Designer. This tool provides a user-friendly interface for designing, documenting, and testing APIs using specifications like RAML or OpenAPI. It allows developers to visually map out the structure of their APIs, define endpoints, and establish the necessary resources and operations without needing to write extensive code. This streamlined process plays a crucial role in ensuring that APIs can be effectively integrated and utilized within MuleSoft’s ecosystem.

In contrast, the other choices serve different functions that do not focus specifically on API configuration. For instance, MuleSoft Connector is primarily used for connecting to various external systems and is focused on connectivity rather than API design. DataWeave is a powerful transformation language used to perform data transformations and format conversions but does not itself facilitate API configuration. The Mule SDK is intended for building custom components and connectors rather than directly configuring APIs. Thus, Anypoint API Designer stands out as the designated tool for configuring APIs, streamlining the API development process significantly.
