Cannot call feature flag APIs using OAuth 2.0 tokens

Jira Development

I’m developing an application that needs to interact with the feature flag APIs to read/write information, and am getting a 403 response for my calls.

Could someone please guide me on how to make these calls work? I couldn’t find more information about what “Provider not installed” means in this context.

Request:

POST https://api.atlassian.com/ex/jira/<cloud id>/rest/featureflags/0.1/bulk

[
  {
    "message": "The request failed: Provider '<oauth client id>' not installed in for cloudId '<cloud id>' for types '[FEATURE_FLAGS]'"
  }
]

Looking at the scopes, just in case, the documentation states these are needed:

write:feature-flag-info:jira
delete:feature-flag-info:jira
read:feature-flag-info:jira

And I see them in the access token generated after granting access to my Atlassian account:

  "scope": "delete:feature-flag-info:jira offline_access read:feature-flag-info:jira read:feature-flag:jira-software write:feature-flag-info:jira write:feature-flag:jira-software",
  "https://id.atlassian.com/atl_token_type": "ACCESS",

When I get a list of accessible resources using the same token, I find those scopes as well:

GET https://api.atlassian.com/oauth/token/accessible-resources  

{
    "id": "<cloud id>",
    "url": "https://<my url>.atlassian.net",
    "name": "<name>",
    "scopes": [
      "delete:feature-flag-info:jira",
      "read:feature-flag-info:jira",
      "read:feature-flag:jira-software",
      "write:feature-flag-info:jira",
      "write:feature-flag:jira-software"
    ],
  }

Am I missing more steps?

Thank you in advance!
