View the response schema fields that the REST API returns on the
Response Fields
tab. The response schema fields capture the predictions that you can pass to downstream transformations.
The response schema fields come from the response schema in the REST API request from the API collection. The working field name is the key that the Machine Learning transformation reads from the REST API response. The working field name might replace special characters that the REST API can't process. The field name is the corresponding output field that the Machine Learning transformation uses to represent the response data in the mapping.
Additionally, the ouput fields that are passed to downstream transformations can't contain special characters except for the following characters:
@ # ( )
. The Machine Learning transformation replaces the special characters with an underscore (_).
