Confluence OAuth 403 Error

[rjbrown1]

Greetings All,

We have been attempting to utilize OAuth to access the Confluence API via Alteryx and Curl commands. The OAuth tutorial presented here: https://developer.atlassian.com/cloud/jira/platform/jira-rest-api-oauth-authentication/ works successfully, and I am able to complete REST requests. However when we attempt to use the Access Token that was generated in a CURL command or in Alteryx we are presented with the following error:

Command:
curl -H "Authorization: Bearer <Access_Token>" "https://confluence.url.com/confluence/rest/api/content/78757429/child/attachment?filename=attachment.xlsx"

Response:
{"statusCode":403,"data":{"authorized":false,"valid":true,"errors":[],"successful":false},"message":"User not permitted to view attachments on content: ContentId{id=78757429}"}

I have been able to verify that I can log into Confluence and access the files, as well as confirmed that when I access the API after logging in via a browser and accessing the above link that I receive the JSON data I expect.

I exhausted my knowledge on what i"m sure is a simple fix. There must be something missing in my request header or body that is causing issue. I am hoping that the community may be able to assist.

For reference, I have tried adding the following during my troubleshooting attempts with no success:

-X GET

-H "Content-Type: application/json"

Authorization: Token <Access_Token>

Authorization: OAuth <Access_Token>

Thank you.
