slack user invitation to workspace

Question

while trying to send invitation to users on slack, i am going though error. i hope i get idea from here. here goes my code:

SLACK_INVITE_URL = 'https://example.slack.com/api/users.admin.invite'

def perform(email)
  uri = URI.parse SLACK_INVITE_URL
  response = Net::HTTP.post_form(uri, {
    email: email,
    channels: 'C02G8J689',
    token: ENV['token']
  })
  json_response = JSON.parse response.body
  json_response
  rescue => e
    error = e
  end
end

I am going through this error:

{"ok"=>false,
 "error"=>"missing_scope",
 "needed"=>"client",
 "provided"=>"identify,bot,incoming-webhook,channels:read,groups:read,users:read,usergroups:read,channels:write,chat:write:user,chat:write:bot,usergroups:write"}

Answer 1

You are Missing the client Scope.

You haven't added the client scope which Slack is telling you in the error.

The client scope "Receives all events from a workspace in realtime" which the users.admin.invite

You can read about it here https://api.slack.com/scopes/client and about users.admin.invite https://github.com/ErikKalkoken/slackApiDoc/blob/master/users.admin.invite.md
