A webhook is an outbound flow: one or more HTTP calls Callab makes to another system.
It is created from the same **Add Flow** button as an inbound automation, under the
**Webhook** tab, and listed under **Automations** with the **Outbound** filter. For
the inbound direction see [Automations](/operate/automations); for a tool the agent
calls mid-conversation see [Live Webhook](/build/tools/live-webhook).

## Templates

**Add Flow**, then the **Webhook** tab, shows **Choose Webhook Template**. Each
template is one ready-made call against a connected CRM:

| System | Templates |
|---|---|
| HubSpot | **Update Contact**, **Create Deal**, **Create Company**, **Search Companies**, **Get Deal** |
| Zoho CRM | **Create Note**, **Search Contacts**, **Create Account**, **Get Contact**, **Create Deal** |
| Pipedrive | **Get Person**, **Search Persons**, **Create Note**, **Get Deal**, **Update Person** |
| GoHighLevel | **Create Task**, **Create Contact**, **Update Opportunity**, **Get Pipelines**, **Search Opportunities** |

The list is paged (**Previous**, **Next**) and searchable.

Choosing one turns the same dialog into **Clone Webhook**, with **Webhook Name**
pre-filled (the template's name plus `(Copy)`) and one predefined variable,
`access_token`, set to `{{access_token}}`. **Clone Webhook** saves it; **Back**
returns to the list.

## Start from Scratch

**Start from Scratch** under the **Webhook** tab opens **Create Custom Webhook**, a
wizard in 2 steps.

*Create Custom Webhook: Details, then Steps.*

### Step 1: Details

**Basic Information** is the **Workspace** and the **Webhook Name**. **Predefined
Variables** are static values such as API keys, available to every step and
referenced as `{{variableName}}`; **Add Variable** adds one.

### Step 2: Steps

**Webhook Steps**: **Add Step** opens **Add Integration Step**, the same form as an
integration step: **Method**, **Depends On Step**, **URL**, **Headers**, **Timeout
(sec)**, **Retry Limit**, **Total Step Timeout (sec)** and an optional **Success
Condition** with an expected status code, a response key path and an expected value.
The fields are described in [Automations](/operate/automations#step-2-steps--variables).

**Custom Variables** pass data between steps, exactly as in an integration. A
webhook has no mandatory `results` variable and no mapping step.

Two buttons close the wizard: **Test Flow** runs the steps once so you can check the
response, **Save** creates the webhook.

## Verify

- The webhook is listed under **Automations** with the **Outbound** filter.
- **Test Flow** returns the status code you expected. It is also in the webhook
  row's actions menu under **Automations**, next to **View History**, which opens
  **Integration History Logs** with the result of every run.

## Troubleshooting

- **Add is disabled next to a header.** Both the key and the value are required
  before **Add** activates.
- **The step times out.** Raise **Timeout (sec)** for a slow endpoint, and make sure
  **Total Step Timeout (sec)** still covers every retry.
- **A template's call returns 401.** `{{access_token}}` is not set: connect the
  system under **Connections** or replace the variable's value with a token.
