Currently, Statsig does not provide a direct way to send different types of notifications to different channels in Slack. When setting up the Slack integration, you select a channel to direct all project-level messages. However, once the integration is enabled, you have the option to opt-in to additional notifications such as Health Checks and Statsig system Status Reports. You can also filter change updates by the environment affected.
The notifications will include updates such as when a gate has been edited, which should provide some context about the change. However, the ability to add specific message or rule details is not explicitly mentioned in the documentation.
If you require more specific functionality, it is recommended to reach out to the Statsig team for further assistance. Please note that during the installation process, you instruct the app which channel to send all the messages.
