The Slack integration uses OAuth to connect your Slack workspace and deliver Tarkle Send notifications to your Slack channels.
The connection is active when workspace.slack_access_token is set. Unlike other integrations that use a simple ID or API key field, Slack uses an OAuth flow — clicking Connect redirects you through Slack's authorization screen and back to Tarkle Send.
Connection result: When the OAuth flow completes successfully, the settings page redirects to ?slack_connected=1, which triggers a success toast: "Slack connected." If the flow fails, a slack_error query param carries the error message.
There are no exclusivity restrictions for Slack. It can be active alongside any other integration.
