Distribute Slack Apps
As an ISV or Salesforce partner, you can package Slack apps and distribute them to other Salesforce users and orgs on AppExchange.
We recommend using second-generation packaging (2GP) to distribute Slack apps. A Dev Hub org can own multiple packages and they can use the same namespace. See Second-Generation Managed Packages.
Packaging is available in beta. Distribution of Slack Apps is available only after the beta phase is complete. Users operating under the beta agreement can't distribute Slack apps using the Apex SDK.
