Trying to create a Sharepoint List

Hi all,

I'm working on trying to create a Flow that will create a new Sharepoint list.  I've created the app registration and granted it sites.ReadWrite.all application permissions, and in my Flow i'm using the client ID, tenant ID, and secret key and successfully getting a token and parsing json to get all the returned values.  

When I try to do the POST to actually create the SPList using the Headers: Authorization with the dynamically returned values for <token_type> and <access_token> to the URI{mysiteID}/lists, I'm getting a 401 unauthorized with

"code": "InvalidAuthenticationToken",
"message": "CompactToken parsing failed with error code: 80049217",
I was able to successfully create the list using Graph explorer logged in as myself using the same URI.
What am I missing?
Thanks in advance!

Thanks!! That's what I needed, I was doing it the hard way - requesting a Graph token and authenticating via an the AAD app I created.
