Response is received in Json, Xml, Csv or CsvContent format. This is user-configurable; value of "format" parameter sent in request decides the format of the response.While data is sent in Csv as part of response, a file containing Csv values is sent when format=CsvContent.Sometimes, API can return diagnostic response in plain/text format instead of actual data. When this happens, user will need to send the request again - till they receive actual data. A list of available diagnostic responses can be found here
To receive the response, user will need to send valid "AccessKey" parameter with each request. User can get the accessKey for their use by contacting our Sales Team and making the payment for the data subscription.
