403 Forbidden Add rows to Dataset REST APP

[shri23]

I am using POSTMAN to POST POSThttps://api.powerbi.com/v1.0/myorg/datasets//tables//rows to test and then later integrate in app. I have created separate client app while testing API using http://docs.powerbi.apiary.io, I can add rows to dataset and visual does reflect the same.

Below configuration in POSTMAN for access token (i did authentiction by providing username password here). 

Can someone help why would I get 403 forbidden error?

Hi shri23, Since Postman is one of the REST clients, have you tried others, such as Fiddler, Paw?
