title: Zapier
description: "Sends a set of named fields to a Zapier catch-hook URL, so any Zap can act on what the agent learned during the conversation."
---

**Zapier** sends data to a Zapier webhook. You define the fields, the agent fills
them from the conversation, and the Zap on the other end does the rest: a row in a
sheet, a CRM record, a Slack message.

:::tip[When to use it]
When the destination is one of the thousands of apps Zapier reaches and you do not
want to write an endpoint. For a system with an API you control, a
[Live Webhook](/build/tools/live-webhook) gives you the response back; Zapier is
fire-and-forget.

## Before you start

In Zapier, create a Zap whose trigger is **Webhooks by Zapier**, **Catch Hook**, and
copy the URL it gives you. It starts with `https://hooks.zapier.com/hooks/catch/`.

## Configuring it

Open **Tools** under **Build**, choose **Add tool**, then **Zapier**. After the
[shared fields](/build/tools/overview#fields-every-tool-shares):

| Field | Type | Default | Notes |
|---|---|---|---|
| **Tool Title** | Text | `Zapier Webhook` | Its ID, `zapier_webhook`, is shown under the field. |
| **Description** | Text | `Send data to Zapier webhook` | Say when: `Send the lead to Zapier once the caller has given their name and phone number`. |
| **AI Response** | Text | `Let me process that information through our system.` | |
| **Zapier Webhook URL** | URL | `https://hooks.zapier.com/hooks/catch/` | Required. Your Zap's catch-hook URL. |
| **Fields** | List | 4 defaults | The data sent, one row per field. At least one is required. |

Each field row has a **Field name** and a **Field description**. The name is the
key in the payload: it starts with a letter and uses only lower-case letters,
digits and underscores. The description tells the agent what to put in it and
needs at least 3 characters. **Add Field** adds a row; **Remove field** deletes
one. The defaults:

| Field name | Field description |
|---|---|
| `caller_name` | Name of the caller |
| `caller_phone` | Phone number of the caller |
| `call_summary` | Summary of the call |
| `timestamp` | Call timestamp |

Choose **Add Tool**, then **Save** the agent.

## Behaviour and limits

- The payload is a JSON object with one key per field. Turn the Zap on and send a
  test call so Zapier can sample the fields before you map them.
- Field descriptions are instructions to the agent. `Preferred callback time, as
  the caller said it` gets a better value than `time`.
- Nothing comes back to the agent. If the conversation depends on the result, use
  a [Live Webhook](/build/tools/live-webhook).
- The send is recorded as a tool call on the call's page. See
  [Call details](/operate/call-details).

## Troubleshooting

- **The Zap never fires.** The URL is the placeholder, or the Zap is off. Paste the
  full catch-hook URL and turn the Zap on.
- **Fields arrive empty.** The agent had not collected them yet. Put the
  prerequisites in **Description** so it sends after collecting.
