Documentation pages incorrectly suggest to use the your-domain.atlassian.net instead of the api.atlassian.com one.
The https://developer.atlassian.com/cloud/jira/platform/oauth-2-3lo-apps is the source of truth and provide the correct option to be used as reference while the documentation is being updated.
This is a list of the known documentation pages that are affected, more will be added as we identify them:
The correct URL (api.atlassian.com) is used in the documentation.
The incorrect URL (your-domain.atlassian.net) is used in the documentation.
Replace the your-domain.atlassian.net with the api.atlassian.com as required when using the APIs.
