Which API is used to perform a transformation in the Transformation Service plugin?

• A. transform()
• B. transformerDefinition()
• C. transformerRuelList()
• D. getTransformer()

Answer: (A)

In the Transformation Service plugin, the function you call to actually run a transformation is the transform() API. This method takes your input data and applies the configured transformer definition—the set of mapping rules, field conversions, and logic—to produce the transformed output. The transformer definition is like the blueprint for how data should be transformed, and transform() executes that blueprint on the given data.

Other options are about accessing or configuring the transformation setup rather than performing it. For example, retrieving a transformer definition or the transformer itself is about getting the components you’ll use, not applying them to data. So transform() is the entry point that executes the transformation using the defined rules.
