When attempting to delete a file using a token retrieved from the new create token method of authentication, a 403 forbidden is returned.
Here is a screen shot from Postman showing this: https://shibumi.box.com/s/769268e4bf726b5ee20a
The file that is a candidate for deletion is in the root 'sandbox' folder of the application. The file was uploaded via the v2 api using the 'instant mode' token for authorization.
Two screen shots, Slide1.jpg and Slide2.jpg are at this link: https://shibumi.box.com/s/5c0601d18060910410ca.
Slide1.jpg shows a call to create a file in Postman. The folder id specified in the call is for the root 'sandbox' folder. The auth_token passed in the Authorization header is the 'instant mode' token created by a previous call to create-token.
Slide2.jpg shows a call to delete the file which was created by the request in Slide1.jpg. The same Authorization header is being used which includes the 'instant mode' auth token. The 403 response is shown.
