Also, the JSON response includes the “array” property. So to get “Thomas Edison” here, you would need to get the property “author” of the first item of the “array” property of the JSON object. Or put another way, the property “array[1].author” of the JSON object.
You also need to convert your JSON response to an object! I recommend you watch my tutorial video so that you understand how to parse JSON in Thunkable: API JSON Tutorial (Video).
