Notice which element in each JSON object within the API endpoint response contains the name of the university. Look at the first JSON object that is the list of universities:
"country": "United States",
"name": "Marywood University",
name element contains the name of each university in this JSON object. Make note of the element's name that contains relevant data from a data source, as the ProcessMaker asset requires this element name when configuring which data that asset requires from the Data Connector's Resource response. In this example, the Screen containing the Select List control is the ProcessMaker asset.
