Retrieving information from REST Api with loop from input list

This script is a simple example of communication with a REST API using ETL studio.

An input list is read - an for each entry the REST API is called and information retrieved - so the script contains an example of looping through reading a file until a certain value is reached of EOF (end of file).

Note: The REST API in question needs a token which is not included in this example. The input list is not included either.
