We really MUST have a way to provide access to our Knowledge Base in Confluence for customers by domain name.  If there is a way to embed access in our web app (asp.net) via an API which could grant view-only access this would be good.  We MUST have a way to provide a read-only access to customers without having to manage them individually.  We have about 25 domains which are manageable, but a thousands of users are not manageable.  

We don't want a work-around or something that is cumbersome to us or to our users.  Providing public access does not work for us.  

There appears to be a undocumented api that lets you add a user to a space and it works with api tokens.  For inviting a guest you can use the Jira api to add them to the guest group.  for adding them to a space you can use http request below to invite user 12345:12345678901234567890 to the space with the key DEMO.

curl --request POST \
  --url 'https://adminuser%40domain.com:apitoken@site.atlassian.net/cgraphql?q=ResetExCoSpacePermissionsMutation' \
  --data '[
    {
        "operationName": "ResetExCoSpacePermissionsMutation",
        "variables": {
            "accountId": "12345:12345678901234567890",
            "spaceKey": "DEMO"
        },
        "query": "mutation ResetExCoSpacePermissionsMutation($accountId: String!, $spaceKey: String) {\n  resetExCoSpacePermissions(input:

) {\n    status\n    __typename\n  }\n}\n"
    }
]'

There is another request that lets you list the guest users on the site and their space associations there is a filter to limit it to users that don't have an assigned space.

curl --request POST \
  --url 'https://adminuser%40domain.com:apitoken@site.atlassian.net/cgraphql?q=WebItemLocationQuery%3Asystem.help%2Fpages' \
  --data '[
    {
        "operationName": "GuestDataQuery",
        "variables": {
            "includeSpacesAssigned": false,
            "first": 25,
            "offset": 0,
            "spaceIds": [],
            "spaceAssignmentType": "UNASSIGNED"
        },
        "query": "query GuestDataQuery($first: Int, $offset: Int, $name: String, $email: String, $spaceIds: [ID], $spaceAssignmentType: SpaceAssignmentType, $includeSpacesAssigned: Boolean = true, $groupIds: [String]) {\n  externalCollaboratorsByCriteria(\n    first: $first\n    offset: $offset\n    name: $name\n    email: $email\n    spaceIds: $spaceIds\n    spaceAssignmentType: $spaceAssignmentType\n    groupIds: $groupIds\n  ) {\n    count\n    nodes {\n      accountId\n      displayName\n      email\n      profilePicture

\n      spacesAssigned @include(if: $includeSpacesAssigned) {\n        nodes {\n          id\n          key\n          name\n          icon

\n          {}typename\n        }\n{}        _typename\n      }\n      _typename\n    }\n    pageInfo

\n_    _typename\n  }\n}\n"
    }
]'

No workaround, this is a MUST please... Today, as Atlassian Admin in my company, I have to manage guest in a very time consuming way.

This would save me having to type out hundreds if not thousands of emails. This should be a thing.

This would be super valuable!

This will be very helpful as we need to manage thousands of users.
