Post excel using PowerBI import mode

Hi,

I am trying to POST excel to Power BI as per the import mode specified in https://msdn.microsoft.com/en-us/library/mt243840.aspx.
My requirement is to Post an excel on the local machine to PowerBI. I tried but was facing a 403 i.e Forbidden Response.

I am not really sure of the implementation.

As per https://msdn.microsoft.com/en-us/library/mt243840.aspx the URL to post is https://api.powerbi.com/v1.0/myorg/imports.

But as per http://docs.powerbi.apiary.io/#reference/imports/imports-collection/list-all-imports the URL to post is https://api.powerbi.com/undefined
