Downloading a CSV file through the API is a 2 step process. The first step prepares the download and provides a URL in the response body that can be used for downloading the CSV file. The next step (this one) is to download the file using a GET request with the response body URL. With this endpoint, you can download the credentials, accounts, meters, statements or associated metadata when it is ready.
The first step can be performed using any of the endpoints below.
