My mission is seemingly simple, at least it has that appearance.  I simply need to upload CSV files to an AWS server.  I am registered with account.
First I need to obtain an access token and use that to upload the files. I have not coded anything yet, trying to understand the best approach, I so hope to use Camel-Rest-DSL. It is required to communicate with JSON. But, the authentication part has me stuck, I’m pretty sure it uses OAuth2 auth, RestFul web service and JSON, this should just be a client, I was looking at WSS4J for JAX-RS OAuth2 but I don’t know.  I really appreciate you guys and gals out there that know, please suggest my best approach to accomplish this so I don’t go down too many paths. Thank you!!!

I’ve done it with postman, this is the scenario. The username and password are fictional
*Get Access Token
                uses POST verb
                requires Token Request URL
uses Basic Auth  requires Username = Client ID of tenant ( needs to be encoded base64 )
HEADER parm Content-Type = x-www-form-urlencoded
Content-Type': 'application/x-www-form-urlencoded',
               'Authorization': 'Basic ' + encoded Client ID
Access Token body - grant_type, username, password
Body = username = 5c0642fe-a495-44db-93f7-67034556fa2c061_ingestor
                password = 154f0252d166f27b5e21ef171b03212a79f41a0daf3
                grant_type = password

#returns the access_token as JSON

POST or upload files
uses POST verb
requires Ingestion URL UploadURL

UploadURL=https://apm-ts-query-svc-prd.app-api.aws-usw02-pr.something.io/v2/time_series/

headers =
key Authentication  "Bearer + access Token" (from request access token above)
key Tenant = TenantUUID
key X-GE-CsvFormat = ODB

               authorization: "" + token
