The file slack-invite.js implements an OpenWhisk action which uses the Slack invite API to send an email invitation to join the OpenWhisk Slack team.
The action requires a Slack token to work correctly.
The API call is made in _layouts/slack.html using Nimbella's anonymous action invocation. The token for the API call is uniquely encrypted for this action. Should this token change, the encrypted value can be regenerated with the following Nimbella encryption API, replacing the placeholder <token> with the actual Slack App token.
