Breaking change: Support for any remaining 1.0 REST API endpoints will change for workspaces that have moved administration to admin.atlassian.com

When you move your administration from in Bitbucket Cloud to admin.atlassian.com, the following endpoints will be disabled:

• /invitations
• /1.0/users/{accountname}/invitations

The following endpoints will only support GET requests. POST, PUT, and DELETE requests will be disabled:

• /groups
• /group-privileges

Now that you are using admin.atlassian.com to administer Bitbucket Cloud, you will need to use their APIs: https://developer.atlassian.com/cloud/admin/about/

For more information on the deprecation and removal of our 1.0 APIs, refer to the following developer doc
