Trigger Zaps when Human in the Loop steps run in Zapier

Zapier now lets you trigger Zaps from Human in the Loop steps, so you can launch follow-up workflows whenever a human reviews, approves, or updates data inside your automations.

This how-to guide explains how to enable the Human in the Loop feature, create Human in the Loop steps, and use them to trigger other Zaps in Zapier. You will also see the event data that is sent to the trigger and how to build practical automations on top of it.

What is Human in the Loop in Zapier?

Human in the Loop is a feature in Zapier that pauses a Zap and routes data to a person for review, correction, or decision-making before the workflow continues. This is useful when AI or automated systems need oversight, or when you want a final human approval step.

When enabled, a Zap can send information to a reviewer, wait for their input, then resume or branch the workflow based on their response.

How Human in the Loop triggers work in Zapier

Human in the Loop triggers are special Trigger events that fire whenever a Human in the Loop step runs in any Zap in your account or folder (depending on your settings). That means you can build separate Zaps that listen for those events and react automatically.

The trigger collects key metadata about the Human in the Loop event, including who handled it, what they decided, and the data they reviewed.

Supported Human in the Loop trigger types in Zapier

When you set up a Human in the Loop trigger in Zapier, you can typically choose from several event types, such as:

• When a Human in the Loop task is created
• When a Human in the Loop task is completed
• When a decision or response is submitted
• When a Human in the Loop task is updated or reassigned

The exact set of trigger events depends on your account features and any updates to the Human in the Loop tools.

Prerequisites for using Human in the Loop triggers in Zapier

Before you can trigger Zaps from Human in the Loop steps, make sure you have the following:

• An active Zapier account with access to Human in the Loop features.
• At least one Zap that contains a Human in the Loop step.
• Permissions to manage and edit Zaps in the relevant folder or workspace.

You should also be familiar with creating and publishing Zaps, and with basic Zap editor concepts like triggers, actions, and paths.

Step 1: Enable Human in the Loop in your Zapier workspace

If Human in the Loop is not already available, you may need to enable it in your Zapier account or workspace settings.

1. Sign in to your Zapier account.
2. Open your Settings or workspace configuration page.
3. Locate the section for Human in the Loop or similar experimental features.
4. Turn on the option to enable Human in the Loop for your Zaps.
5. Save your settings and refresh the Zap editor if needed.

Once enabled, you will be able to add Human in the Loop steps directly in the Zap editor.

Step 2: Add a Human in the Loop step to a Zap in Zapier

Next, create or edit a Zap where you want to pause for human review.

1. In Zapier, create a new Zap or open an existing one.
2. Set up your usual trigger (for example, a form submission, CRM event, or webhook).
3. Click + to add a new action step at the point where you want a human review.
4. Choose the Human in the Loop app or step type in the editor.
5. Configure the information that will be sent to the reviewer, such as:

• Fields and values to inspect
• Suggested actions or choices
• Any AI-generated output that needs checking

6. Save the step and continue configuring the rest of your Zap, including what happens after the review is completed.
7. Turn the Zap on once you have tested it.

Every time this Human in the Loop step runs, Zapier can now emit an event that other Zaps can use as a trigger.

Step 3: Create a Zap with a Human in the Loop trigger in Zapier

Now you will create a separate Zap that starts whenever a Human in the Loop event occurs.

1. In Zapier, click Create Zap.
2. In the trigger search box, type and select Human in the Loop (or the internal app/connector that exposes these events).
3. Choose a specific trigger event, such as:

• “Human in the Loop step completed”
• “Human in the Loop task created”
• “Human in the Loop decision submitted”

4. Connect the appropriate account or workspace if prompted.
5. In the trigger settings, filter or scope which Human in the Loop steps should fire this Zap, for example by:

• Folder or project
• Zap name or ID
• Specific step identifiers or labels

6. Test the trigger to pull in a recent Human in the Loop event.
7. Confirm that you see the expected sample data.

This new Zap will run every time the selected Human in the Loop event type is triggered in your account.

Step 4: Review the Human in the Loop trigger data in Zapier

Each Human in the Loop trigger in Zapier includes structured fields that describe the event. While the exact payload can evolve, it commonly includes:

• Task or step ID: Unique identifier for the Human in the Loop step instance.
• Zap name or ID: The Zap that produced the Human in the Loop step.
• Reviewer details: Email or ID of the person who reviewed the data, if applicable.
• Status: Information like created, in progress, or completed.
• Decision or outcome: Choices selected by the reviewer, such as approve, reject, or custom options.
• Comments or feedback: Free-text feedback from the reviewer.
• Original data: The payload that the reviewer saw and potentially edited.

When you map this data into later steps in the Zap, you can create conditional logic, notifications, and system updates based on human decisions.

Step 5: Add actions that respond to Human in the Loop events in Zapier

After setting up the trigger, build the rest of your Zap to respond to the Human in the Loop event.

1. Click + to add an action step after the Human in the Loop trigger.
2. Choose the app or service you want to update, such as:

• Email, chat, or notification tools
• CRMs and databases
• Project management platforms
• AI tools and custom APIs

3. Map fields from the Human in the Loop trigger data to your action inputs, for example:

• Use the decision outcome to set a status field.
• Include reviewer comments in internal notes.
• Pass corrected data to your database or downstream system.

4. Optionally add Filter or Path steps so the Zap only continues for certain decisions.
5. Test the Zap by running through a full Human in the Loop flow in the original Zap, then verifying that the new Zap runs as expected.
6. Turn the Zap on when testing is complete.

Common use cases for Human in the Loop triggers in Zapier

Using Human in the Loop triggers in Zapier opens up many workflow possibilities, such as:

• Approval workflows: Trigger downstream processes when a human approves or rejects a request.
• Quality assurance: Log corrections made by reviewers and feed them into reporting or training sets.
• Escalations: Notify a manager or create a task when a reviewer flags an item for escalation.
• Compliance checks: Record manual compliance reviews and store structured decisions for audits.

By combining Human in the Loop with other automations in Zapier, you can keep humans in control of critical steps without losing the benefits of automation.

Best practices for configuring Human in the Loop triggers in Zapier

To get the most out of Human in the Loop triggers, consider these tips:

• Use clear labels for each Human in the Loop step so you can easily filter which events should trigger other Zaps.
• Limit each trigger Zap to a specific event type or workflow to keep logic simple and maintainable.
• Log all key decisions in a central system (like a spreadsheet or database) for later analysis.
• Combine triggers with conditional logic so that only certain decision outcomes proceed to follow-up actions.
