How to connect Lark and Slack
Create a New Scenario to Connect Lark and Slack
In the workspace, click the โCreate New Scenarioโ button.

Add the First Step

Triggers can be scheduled, called by a Lark, triggered by another scenario, or executed manually (for testing purposes). In most cases, Lark or Slack will be your first step. To do this, click "Choose an app," find Lark or Slack, and select the appropriate trigger to start the scenario.

- Branching: Create multiple branches within the scenario to handle complex logic.
- Merging: Combine different node branches into one, passing data through it.
- Plug n Play Nodes: Use nodes that donโt require account credentials.
- Ask AI: Use the GPT-powered option to add AI capabilities to any node.
- Wait: Set waiting times, either for intervals or until specific dates.
- Sub-scenarios (Nodules): Create sub-scenarios that are encapsulated in a single node.

Save and Activate the Scenario
After configuring Lark, Slack, and any additional nodes, donโt forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking โRun onceโ and triggering an event to check if the Lark and Slack integration works as expected. Depending on your setup, data should flow between Lark and Slack (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Lark and Slack
Lark + Jira + Slack: When a new message containing a keyword indicating a critical issue is posted in a Lark group chat, a Jira issue is automatically created. The relevant Slack channel is then notified about the new Jira issue.
Slack + Lark + Google Calendar: When a message in Slack indicates a meeting and its date/time, this flow creates corresponding events in both Lark and Google Calendar. The Lark and Google Calendar events will mirror the information from the Slack message.
