# Webhook status

A [Webhook](/api/smartsheet/openapi/webhooks/webhook) object's `enabled` attribute indicates whether a webhook is enabled or disabled, while the `status` attribute describes the *reason* that the webhook is enabled or disabled.

> **Note:**
* When a Webhook object's `enabled` attribute is set to `true`, Smartsheet is monitoring for the specified events and sends a callback (see the **Event Callbacks** section) to the `callbackUrl` when the events occur.
* When a Webhook object's `enabled` attribute is set to `false`, Smartsheet is not monitoring for the specified events and does not send a callback to the `callbackUrl` when the events occur. Depending on the value of the `status` attribute, it may be possible to (re-)enable the webhook. (See below for details).



The following table lists all possible combinations of `enabled` and `status` attribute values.

| Webhook.enabled | Webhook.status | Meaning | Notes |
|  --- | --- | --- | --- |
| `true` | `ENABLED` | Webhook is active. |  |
| `false` | `NEW_NOT_VERIFIED` | Webhook has been created but is not enabled because it has not yet been verified. | Owner can re-enable the webhook by using the [Update webhook](/api/smartsheet/openapi/webhooks/updatewebhook) operation to set `enabled` to `true`. Once the subscriber successfully acknowledges the verification request (see the **Webhook Verification** section), the webhook is enabled. |
| `false` | `DISABLED_ADMINISTRATIVE` | Webhook has been disabled by Smartsheet support. | A webhook in this state can only be re-enabled by Smartsheet (contact Support).  Attempting to re-enable a webhook in this state results in error code 1154. |
| `false` | `DISABLED_APP_REVOKED` | Webhook has been disabled because the third-party app associated with the webhook has had its access revoked. | This is a terminal state (that is, webhook in this state cannot be re-enabled, and attempts to do so result in error code 1153). If the third-party app's access is subsequently restored, it must create new webhooks. |
| `false` | `DISABLED_BY_OWNER` | Webhook has been disabled by the owner. | Owner can re-enable the webhook by using the [Update webhook](/api/smartsheet/openapi/webhooks/updatewebhook) operation to set **enabled** to **true**. Once the subscriber successfully acknowledges the verification request (See the **Webhook Verification** section), the webhook is enabled. |
| `false` | `DISABLED_CALLBACK_FAILED` | Webhook has been disabled because callback was not successfully delivered to the callback URL. | Owner can re-enable the webhook by using the [Update webhook](/api/smartsheet/openapi/webhooks/updatewebhook) operation to set `enabled` to `true`. Once the subscriber successfully acknowledges the verification request (see the **Webhook Verification** section), the webhook is enabled. |
| `false` | `DISABLED_EXCEEDED_GRID_LIMITS` | Sheet webhook has been disabled because the sheet has 20,000 rows, 400 columns, or 500,000 cells. | Owner can enable the webhook by first reducing the sheet size to within the specified limits and then executing the [Update webhook](/api/smartsheet/openapi/webhooks/updatewebhook) operation with the `enabled` body attribute set to `true`. |
| `false` | `DISABLED_SCOPE_INACCESSIBLE` | Webhook has been disabled because its owner lost access to the corresponding data in Smartsheet (either because the object was deleted or sharing permissions were revoked). | Webhook is automatically re-enabled if access to data is restored (for example, if deleted object is restored or sharing permissions are restored). |
| `false` | `DISABLED_VERIFICATION_FAILED` | Webhook verification has failed. | Owner can re-enable the webhook by using the [Update webhook](/api/smartsheet/openapi/webhooks/updatewebhook) operation to set **enabled** to **true**. Once the subscriber successfully acknowledges the verification request (see the **Webhook Verification section), the webhook is enabled. |
