Access Fusion Team using REST API from external application

[akhil_mora]

Hello Autodesk Community,

I am using Fusion team. I would like to extract a given project and model on my Fusion team via REST API using the end points. I had a look at this documentation: https://aps.autodesk.com/en/docs/oauth/v2/developers_guide/overview/ 
However it always starts with creating an application. In my case, I have my own application. Is it possible to authenticate from my application and connect to the Fusion team end points?
Any help is highly appreciated.
Thanks in advance,
Akhil.

An Application in the APS portal gives you access to the client id and secret that you need to make calls to the Autodesk ecosystem. It also defines the callback URL that will be used after login to redirect the user back to your application (if you are building a web app). The tutorial that demonstrates getting a three legged token shows how you can authorize your existing web application to get data from Autodesk services:

https://aps.autodesk.com/en/docs/oauth/v2/tutorials/get-3-legged-token/

Once your application is authorized by the user, you can then use that bearer token to make further downstream calls to APIs like the Data Management API to get data from Fusion Team.
