The Atlassian (Jira & Confluence) app uses OAuth 2.0 (3LO). Instead of pasting keys, you authorize the connection from the Dex admin console and grant Dex the right scopes.
Steps
1In Dex, go to Settings → Integrations / Connected Providers → Atlassian.
2Click Connect (or Reconnect) and complete the Atlassian consent screen.
3On the consent screen, make sure to select the site(s) you want Dex to access.
4Grant the Jira scopes: read:jira-work, write:jira-work, read:jira-user, manage:jira-project.
5Grant the Confluence scopes: read:confluence-space.summary, read:confluence-content.summary, read:confluence-content.all, write:confluence-content, search:confluence, read:confluence-user.
6Once the OAuth flow completes and the token is stored, Dex continues with discovery (projects, issue types, and Confluence spaces).
Paste into Dex
Nothing to paste — this connection is authorized directly through the OAuth consent flow from the Dex admin console (see the steps above).
