Create multi-party channel on behalf of another user (slack API)

I have an application in which I need to create multi-party im groups in slack, and then provide a url to the user to access the group.

First, user A in a given client organization A_org registers their license of the app with slack using slacks Oauth2 method.

Later on, user B (not the user who originally registered the app / created the auth token), needs to access a multi-party group messaging channel.

Currently, I am creating the group as so:

const response = await callSlackApiMethod('mpim.open', {
  token: access_token, // <-- access token of authorizing user (user A)
  users: slackIds.join(',') // <-- group of users including B, not including A
});

where callSlackApiMethod simply GETs the REST method from slack with provided params.

The Problem:

The group returned in response always includes the slackId of user A. Is there a way to create a mpim channel for user B (and other users), not including user A, and without having to seprately authorize each user?

Thanks in advance!

No, that is not possible with mpim.open. Using the token of user A to create the mpim channel is the same as user A inviting other users into a group conversation.

But you can create a new private channel with groups.create instead and invite user B to it. It will also include user A at first, but user A can leave the private channel so that only user B (and any other invited users) remains.

Please note though, that by leaving the private channel with user A you loose control over it in your script. You will not be able to re-enter or manage it in any way. A workaround that I have been using is to have a admin user account (e.g. slackadmin) which can stay in private channel without appearing as a "spying user".
