The verifier that you create is available to the users who create mappings. You add a Verifier transformation to a mapping and then add a verifier asset to the transformation. The Verifier transformation applies the logic in the verifier asset to the data source that the mapping identifies.
A Verifier transformation works in a similar way to a Mapplet transformation. You connect the transformation inputs and outputs to other objects in the mapping in the same manner as a mapplet connects to other mapping objects. When you run the mapping, the Verifier transformation applies the verifier logic to the input data and generates output data for downstream objects.
