# Base-Wide Webhooks

> Watch all record or schema changes in an Airtable base with a single webhook registration.

Instead of registering separate webhooks for each event type, you can use **base-wide** events to monitor an entire Airtable base with one registration.

## Overview

| Registration event    | What it watches                                                    | Outgoing payload `event` values                                                                   |
| --------------------- | ------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------- |
| `base_records_change` | New, updated, and deleted records in **all tables**                | `create`, `update`, `delete`                                                                      |
| `base_schema_change`  | Table and column create, update, and delete in the **entire base** | `table_create`, `table_update`, `table_delete`, `column_create`, `column_update`, `column_delete` |

<Info>
  The registration event type (e.g. `base_records_change`) does **not** appear in outgoing payloads. You always receive the granular event that actually occurred.
</Info>

## Register via API

Use the [Register Webhook](/docs/api-reference/post/webhooks/register) endpoint and select the **Watch Base Record Changes** or **Watch Base Schema Changes** schema.

### Base record changes

```json theme={null}
{
  "baseId": "appkGlXEiufQLn1Qd",
  "event": "base_records_change",
  "coalesceUpdates": true,
  "webhookUrl": "https://hook.eu1.make.com/your-unique-hook-id"
}
```

* Do **not** pass `tableId` or `columnId`.
* Set `coalesceUpdates: true` to group rapid updates to the same record into one webhook (saves Make/Zapier/n8n task usage).

### Base schema changes

```json theme={null}
{
  "baseId": "appkGlXEiufQLn1Qd",
  "event": "base_schema_change",
  "webhookUrl": "https://hook.eu1.make.com/your-unique-hook-id"
}
```

* Do **not** pass `tableId`, `columnId`, or `coalesceUpdates`.

## Register via Dashboard

1. Open the dashboard and click **Add Webhook**.
2. Choose **Base Record Changes (all tables)** or **Base Schema Changes (all tables/columns)**.
3. Select the base and enter your webhook URL.
4. For base record changes, optionally enable **Coalesce rapid updates**.

## Important notes

<Warning>
  **Duplicate deliveries:** If you also have table-specific webhooks (e.g. `record_create` on the same table), you will receive **two** webhooks for the same change.
</Warning>

<Warning>
  **High traffic:** `base_records_change` on large bases can generate many webhooks. Use `coalesceUpdates` to reduce update bursts; it does not affect create or delete events.
</Warning>

## When to use base-wide events

* **Sync pipelines** that need every record change across a base without maintaining per-table webhooks.
* **Schema sync** to external databases or documentation when any table/column change should trigger a rebuild.
* **Audit logging** of all structural changes in a base.

For single-table or single-column precision, use the individual event types documented in [Table Events](/docs/table-events) and [Column Events](/docs/column-events).
