Authentication error when trying to get dynamic refresh token using Power Query

[atharsana]

Hi Community, 

I am connecting my data through Web(using advanced section) in PowerBi. The data can be fetched using the Bearer type access token generated from postman. Since the Access token is valid only for short period of time, I have used a query to have the refresh token dynamic. 

But on applying the query, it throws a error like cannot authenticate with credentials provided, despite the credentials given are correct. Also it says the data can only be fetched by Anonymous method.

Help me to overcome this error
Thankyou

Hi @atharsana 

What is your data source? 

Maybe you can try other types of Authentication, like windows or organizational account.
If the above one can't help you, could you please provide more detailed description of your connection flow.

Best Regards
