Zapier makes it easy to integrate LASSO with Slack - no code necessary. See how you can get setup in minutes.
Choose a trigger
A trigger is the event that starts your Zap—like a "List Client Addresses" from LASSO.
Add your action
An action happens after the trigger—such as "Add Reaction" in Slack.
You’re connected!
Zapier seamlessly connects LASSO and Slack, automating your workflow.
Supported triggers and actions
Zapier helps you create workflows that connect your apps to automate repetitive tasks. A trigger is an event that starts a workflow, and an action is an event a Zap performs.
