This is a beta Integration, which lets you implement and test pre-release software. Since the integration is beta, it might contain bugs. Updates to the integration during the beta phase might include non-backward compatible features. We appreciate your feedback on the quality and usability of the integration to help us identify issues, fix them, and continually improve.

Navigate to Settings > Integrations > Servers & Services.
Search for SlackV3.

Click Add instance to create and configure a new integration instance.

Backwards Compatibility with Slack V2#

Slack V3 currently contains improvements to enhance the stability of the integration as well as the circumvention of OProxy. This version is intended to provide customers with more granular control over the Slack integration by enabling the Bring-Your-Own-App model and customizable scope-based authentication.

All commands are fully compatible with Slack V2 playbooks as their inputs and outputs have remained the same. As a customer, you should notice no significant change in the behavior of the Slack integration with your existing playbooks.

Known Limitations#

SlackV3 mirrors incidents by listening to messages being sent in channels the bot has been added to. Because of this, you may have some users in Slack who are not users in XSOAR. This will occasionally cause the module health to indicate that an error has occurred because a user was unable to be found. In this circumstance, the error is expected and is purely cosmetic in nature.

Please note: If a dedicated channel is configured, however there are no notifications being sent, please verify that the Types of Notifications to send parameter is populated.
