How to connect Power BI to AWS in Power BI?

[Analitika]

Hi,

I would like to ask how I could connect to AWS Power BI. I mean I have an API REST API and it can be authenticated using AWS Signature. But how to authenticate it in Power BI. I have tried to get data API with paramters like access_key_id, secret_key_id, session token etc. But still getting access is forbidden. So  how I could resolve this issue?
