How can I Add a contact as User in a Workspace in Slack

[Stoyan_Vatov]

Hello,

there is no direct module for this, yes, but it looks like you can still do it via a generic API call:

https://api.slack.com/admins/workspaces#inviting

You will need the admin.users:write scope available in the connection and then you can call the admin.users.invite endpoint to send an invitation.
