Following this similar question, posted a year ago, Where is the official documentation on how to retrieve an access token? I saw the two answers to the prior question were vastly different in methods. Other APIs I've worked with had a much simpler way to obtain a bearer/access token.
Could someone currently working with Sharepoint API provide how they request an access token for requests like this:
GET https://{site_url}/_api/web/lists/GetByTitle('List Title')
Authorization: "Bearer " + accessToken
Accept: "application/json;odata=verbose"
