App instances need to explicitly call asOAuthApp(true) to turn on them. As the OAuth flow handling features are unnecessary for many custom apps, those are disabled by default.

Here is a Bolt app demonstrating how to implement OAuth flow. The URLs are usually somewhere else but Bolt has simple functionality to serve them.Provide the endpoints to navigate installers for the completion/cancellation of the installation flow.Complete the installation by calling oauth.v2.access (or oauth.access if you maintain legacy OAuth apps) method and store the acquired tokens.Make sure if the state parameter is valid.Provide an endpoint to handle user redirection from Slack.Append client_id, scope, user_scope (only for v2), and state to the URL.Generate a state parameter value to verify afterwards.Provide an endpoint starting OAuth flow by redirecting installers to Slack’s Authorize endpoint with sufficient parameters.What Your Bolt App DoesĪll your app needs to do to properly handle OAuth Flow are: Org wide installations can be enabled in your app configuration settings under Org Level Apps. To know how to configure such settings, consult the list of the available env variables below in this page.īolt for Java automatically includes support for org wide installations since version 1.4.0. To enable App Distribution, visit the Slack App configuration page, choose the app you’re working on, go to Settings > Manage Distribution on the left pane, and follow the instructions there.įor Redirect URL, Bolt apps respond to app's public URL domain}/slack/oauth/callback if you go with recommended settings. By setting an OAuth Redirect URL and enabling App Distribution, the app becomes to be ready for installation in any other workspaces. A newly created Slack app can only be installed in its development workspace in the beginning.
