REST API get dataset data - Datasets - Execute Queries

Hi. How do you want to connect? I mean, you can open Power Bi Desktop and get data from PowerBi Datasets to build new reports from a current dataset. The admin must have the connection across datasets turned on.

If you just want to use a language code to get specific thing from a dataset, you can use the rest api. It would be this request:
https://docs.microsoft.com/en-us/rest/api/power-bi/datasets/execute-queries-in-group

If you find hard to use the API you can use libraries depending on the language. For example you can import SimplePBI for python or use cmdlets for power bi on PowerShell.

Be sure to read the Considerations and Limitations on the link above.

I hope that helps,
