Sends a HTTP request for each record and retrieves the response as transformation output.

For each request you can have dynamic elements in the URL or in the request body that is sent. Provide variable names that are unique to the URL and request body and reference them there. For instance:

URL:http://www.google.com/?q=${term}
Input:column1
Variable:${term}
