    You can potentially leverage the column filter options as listed at the top of this page, but it doesn't explicitly state the number of rows that you can retrieve: 

     

    https://developer.domo.com/docs/dataset-api-reference/dataset#Export%20data%20from%20DataSet

     

    I don't think they offer the capability to limit the row return count just yet though for the Dataset API.

    You can user the "query a dataset" version of the dataset API. It works great for aggregating data, even from large datasets. here is a powershell example of the query:

     

    $query = '{"sql": "select sum(gross_sales_less_returns) from table where fiscal_date = '+"'" +$Yesterday +"'::DATE group by fiscal_date"+'"}'

     

    The call then looks like this:

     

    $data = Invoke-RestMethod -Method POST -Uri "https://api.domo.com/v1/datasets/query/execute/$datasetId" -body $query -Headers $headers -ContentType 'application/json;charset=UTF-8'

    I check the amount of yesterday's sales in case something broke upstream and my dataset updated with nothing from yesterday before sending out reports. 

     

    Hope that helps.
