Report API return fields in different order

I was investigating the data captured by OneSpan and made available through the REST API and also, if I can use PowerBi to display the data. I am trying to use the completion report API (https://developer.esignlive.com/guides/feature-guides/completion-report/#rest-api). One issue that I am running into is the fact that OneSpan seems to reorder the columns. (See attached images). In this case, I am using the “Accept” header and its set to text/csv. A similar issue seems to be occurring with JSON. Especially with the CSV based return data, the reordering of columns causes PowerBi to not be able to read the data correctly, as the columns keep changing. I was wondering if there is parameter that can be passed to fix the column order for both the CSV and the JSON data returned?
