# Update Webhook

`PATCH /v0/webhooks/{webhook_id}`

Update inbox or pod subscriptions, or replace the webhook's `event_types` in full when you pass a
non-empty `event_types` array (see request field docs). Inbox and pod changes use add/remove lists.

**CLI:**
```bash
agentmail webhooks update --webhook-id <webhook_id> --add-inbox-id <inbox_id>
```

## Path parameters

- `webhook_id` string, required — ID of webhook.

## Request body

- WebhooksUpdateWebhookRequest — Update an inbox-scoped webhook. It is fixed to its inbox, so only `event_types` can change.
  - `event_types` EventType[] — Event types for which to send events.

## Response `200`
