Getting 404 and 403 using Rest API and Rest API V2

[Mohammad Zaman]

Hello, 

I am trying to call Confluence Cloud V2 Rest API using the access token by using 3LO Authentication mechanism (code grant). 

I can generate an Access_Token and also see correct scopes.

I tried using the REST API and REST API (v2). 

I get the pageId from the Page Information
{ATLASSIAN_DOMAIN}/wiki/pages/viewinfo.action?pageId=2654211

Using Rest API V1:  (DEPRECATED)

curl --location --request GET 'https://{ATLASSIAN_DOMAIN}/wiki/rest/api/content/{id}' \

--header 'Authorization: Bearer {ACCESS_TOKEN}


RESPONSE:

{

"message": "Current user not permitted to use Confluence",

"statusCode": 403

}

Using Rest API V2: There is no API documentation for v2 for getting content by pageId.
However, I tried using the V2 GET Page By Id:

Get Page By Id V2 

curl --location --request GET 'https://{domain-name}.atlassian.net/wiki/api/v2/pages/2654211' \
--header 'Authorization: Bearer {ACCESS_TOKEN}' \
--header 'Accept: application/json'

Response: 

{
  "errors": [
    {
       "status": 404,
       "code": "NOT_FOUND",
       "title": "Not Found",
       "detail": null
    }
  ]
}

 
I can retrieve and see the scopes by calling 
https://api.atlassian.com/oauth/token/accessible-resources
with the Access_Token:

curl --location --request GET 'https://api.atlassian.com/oauth/token/accessible-resources' \
--header 'Authorization: Bearer {ACCESS_TOKEN}' \
--header 'Accept: application/json'
