How Zapier works
Zapier makes it easy to integrate Human in the Loop with Socket - 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 "New Approval Requested" from Human in the Loop.
Add your action
An action happens after the trigger—such as "Create Client" in Socket.
You’re connected!
Zapier seamlessly connects Human in the Loop and Socket, 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.

ActionWrite- Lead Created
Triggers when a lead is created in Socket, however it arrived - a Socket form, the API, another Zap, or a practitioner adding it by hand.
Try ItTriggerInstant - Lead Stage Changed
Triggers whenever a lead moves between pipeline stages, including your own custom stages. Also fires when a lead is won or lost - use the dedicated Lead Won and Lead Lost triggers if you only want those. Does not fire when a stage is deleted and its leads are moved on.

ActionWrite- Form Response Submitted
Triggers when a form response is submitted, on any submission route (public link, direct send, or proposal onboarding).
Try ItTriggerInstant - Lead Lost
Triggers when a lead reaches the Lost stage, whether it was marked as lost directly or its proposal was lost or deleted.
Try ItTriggerInstant - Lead Won
Triggers when a lead reaches the Won stage, which happens when its proposal is won. Leads created from an already-won proposal do not fire this - the win predates the lead.
