Why am I getting 401 "scope does not match" when accessing Confluence /spaces API via OAuth 2.0?

[aqi-bagus]

I'm building an app that uses 3-legged OAuth (3LO) to publish meeting notes from my web app to Confluence Cloud. I successfully obtained access tokens via the authorization flow.

However, when I try to call:

`GET https://api.atlassian.com/ex/confluence/{cloudId}/wiki/api/v2/spaces`

I get the following error:

code 401
message Unauthorized; scope does not match

I made sure to request these scopes during login:

• read:confluence-space.summary

• read:page:confluence

• write:page:confluence

• "read:confluence-content.summary"

And I confirmed the client ID, redirect URI, and cloudId are correct.

Do I need additional scopes? Or is there something I need to configure in the Atlassian Developer Console?

Thanks!

Hi @aqi-bagus !

Hi, I recommend checking the scopes again. Also try to add read:confluence-content.all

I recommend checking this article:
