RN if your instance is OS Cloud hosted, you will have to use a hard-coded "Personal Access Token" provided by the OneStream IdentityServer - see page 59 of Identity_and_Access_Management_Guide.pdf

It appears the design intent of the REST API is automation of processes run by a machine account.  

REST API comes in two flavors(versions): 5.2.0 and 7.2.0.  5.2.0 is send a request and wait for it to complete, Get.  7.2.0 is more fire and forget, though the docs are not clear when this (asynchronous) topology is used.  I think we can assume DM can be called Asynchronously using Post.

It's possible that 8.2.2 is not the right version to use in the API call.  Try 5.2.0 or 7.2.0

Thanks for your quick response. I'm getting the same error when I tried with 7.2.0 but when I tried to with 5.2.0, I'm getting below error.

Request Status: 401 Unauthorized 

Result: Non-200 response code received: 401

401 response typically means it did not like/accept the token you passed it in the authorization header.  

Did you create the token request in a prior request?
