Pull data from a REST API which has Authentication


New to PowerBI so please forgive me if query does not make complete sense!

I have PowerBI Desktop and want to get date from a REST web service.


The issue I have is the web service requires an authentication first, before I can call the methods for data I want.

The product is Traverse.


So, to logon I first have to issue command like;



This authenticates me and returns success if logged on, I see in POSTMAN that a cookie is created for session.


Once I have done that I can call upon its many methods to pull data out, these are the methods I need access to for PowerBI



to get me json back with report data I want to pull into PowerBI to then produce charts and such


What I cannot see is a method to call the second URL without the authentication. The Get Data from Web source does not seem to accomodate this type.

Is there a way to do this with the Advanced Editor?


Thanks in advance

Re: Pull data from a REST API which has Authentication


Please verify that if your web service supports "Basic" authentication or some headers such as subscription key, it is possible to use these authentication types in Advanced Editor.

There is a blog for your reference.

Re: Pull data from a REST API which has Authentication

I have posted query on Traverse community site but not had a response. From their developer guide it looks like the only option I have is the URL to logon as a pre step to the data URL request as described in opening post.


I may have to write a wrapper web service so I can send request through, do the URL authentication and request before returning data. Didnt want to do that as time consuming and additional overhead.
