# Webhooks

## Create Organization Webhook Endpoint

`BetaNewOrganizationWebhookEndpoint Beta.Organization.Webhooks.Create(parameters, cancellationToken = default)`

**POST** `/v1/organizations/webhooks`

Create an organization webhook endpoint.

An organization webhook endpoint belongs to the organization rather than to one of its workspaces. An organization can have at most 32 organization
webhook endpoints, enabled or disabled.

The response includes the endpoint's signing secret. No read returns it, so store
it when you receive it.

Every request must include the beta header `anthropic-beta: webhooks-2026-10-07`. A request without it returns `404`, exactly as if this API did not exist. Anthropic turns organization webhook endpoints on for each organization; until yours is on, requests also return `404`. Organization webhook endpoints are in beta and are not available to organizations with HIPAA readiness enabled.

### Parameters

  - `required IReadOnlyList<EnabledEvent> enabledEvents`

    The event types to deliver to the endpoint. Must list at least one.

    - `UserProfileEnforcementActionOpened("user_profile.enforcement_action_opened")`

    - `UserProfileEnforcementActionResolved("user_profile.enforcement_action_resolved")`

  - `required string url`

    minLength: 1

  - `string description`

    Notes about the endpoint.

  - `string name`

    A short label for the endpoint.

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

## List Organization Webhook Endpoints

`WebhookListPage Beta.Organization.Webhooks.List(parameters, cancellationToken = default)`

**GET** `/v1/organizations/webhooks`

List the organization's webhook endpoints.

An organization webhook endpoint belongs to the organization rather than to one of its workspaces. The list does not include webhook endpoints that
belong to a workspace.

Every request must include the beta header `anthropic-beta: webhooks-2026-10-07`. A request without it returns `404`, exactly as if this API did not exist. Anthropic turns organization webhook endpoints on for each organization; until yours is on, requests also return `404`. Organization webhook endpoints are in beta and are not available to organizations with HIPAA readiness enabled.

### Parameters

- `WebhookListParams parameters`

  - `string? afterID` (query parameter)

    ID of the object to use as a cursor for pagination. When provided, returns the page of results immediately after this object.

  - `string? beforeID` (query parameter)

    ID of a webhook endpoint to use as a cursor. Returns the first `limit` endpoints that come before it in list order, not the `limit` endpoints just before it.

  - `long limit` (query parameter)

    Number of items to return per page, up to `100`. The default, `0`, means `20`.

    minimum: 0, maximum: 100

  - `Order? order` (query parameter)

    Sort order by `created_at`. Defaults to `desc`, newest first.

    - `Asc("asc")`

    - `Desc("desc")`

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

    This endpoint is in beta: requests must send `webhooks-2026-10-07` in this header.

## Update Organization Webhook Endpoint

`BetaOrganizationWebhookEndpoint Beta.Organization.Webhooks.Update(parameters, cancellationToken = default)`

**POST** `/v1/organizations/webhooks/{webhook_endpoint_id}`

Update an organization webhook endpoint. Only the fields you send are changed.

Every request must include the beta header `anthropic-beta: webhooks-2026-10-07`. A request without it returns `404`, exactly as if this API did not exist. Anthropic turns organization webhook endpoints on for each organization; until yours is on, requests also return `404`. Organization webhook endpoints are in beta and are not available to organizations with HIPAA readiness enabled.

### Parameters

- `WebhookUpdateParams parameters`

  - `required string webhookEndpointID` (path parameter)

    ID of the webhook endpoint.

    maxLength: 2048

  - `string description`

    Notes about the endpoint.

  - `IReadOnlyList<EnabledEvent> enabledEvents`

    The event types to deliver to the endpoint. Replaces the whole set; an empty list leaves it unchanged.

    - `UserProfileEnforcementActionOpened("user_profile.enforcement_action_opened")`

    - `UserProfileEnforcementActionResolved("user_profile.enforcement_action_resolved")`

  - `string name`

    A short label for the endpoint.

  - `State state`

    `disabled` stops deliveries. `enabled` resumes them and clears `disabled_reason`. Events that happen while the endpoint is disabled are never delivered.

    - `Disabled("disabled")`

    - `Enabled("enabled")`

  - `string url`

    The HTTPS URL that deliveries are sent to.

    minLength: 1

  - `IReadOnlyList<AnthropicBeta> betas` (header parameter)

    This endpoint is in beta: requests must send `webhooks-2026-10-07` in this header.

```csharp
using System;

WebhookRegenerateSigningSecretParams parameters = new()
{
    WebhookEndpointID = "webhook_endpoint_id"
};

var betaOrganizationWebhookEndpointSigningSecret = await client.Beta.Organization.Webhooks.RegenerateSigningSecret(parameters);

Console.WriteLine(betaOrganizationWebhookEndpointSigningSecret);
```
