## Description

Returns the delivery status of one event, by the event id the webhook carried, for the calling API client on this tenant.

## Request Parameters

| Name | In | Required | Schema | Description |
|---|---|---|---|---|
| eventId | path | true | string:uuid | The id the delivered webhook carried |
| Thomas-Tenant-Id | header | true | string:uuid | Required for API clients: the Tenant this call acts in. Send exactly one. Signed-in users don't send it — their Tenant comes from their session. The header only selects the Tenant; your Grant for it decides access, and is checked on every call. |

## Request Body

None.

## Responses

| Status | Description | Schema refs |
|---|---|---|
| 200 | The delivery status of the event | #/components/schemas/WebhookDeliveryStatusItemResponseDto |
| 400 | The event id or the tenant selector was refused | #/components/schemas/ApiErrorResponseDto |
| 401 | Invalid or missing authentication token (AUTH_TOKEN_INVALID) | #/components/schemas/ApiErrorResponseDto |
| 403 | Only a Partner-owned API client may call this operation; a signed-in person, a service account and a Partner acting on behalf of a person are refused (PRINCIPAL_TYPE_NOT_ALLOWED). An API client is refused before any tenant data is read or changed when its tenant context, Grant or scope does not authorise the operation (AUTH_TENANT_NOT_GRANTED), or when its service membership is absent (AUTH_SERVICE_MEMBERSHIP_MISSING). An API client holds no organisation role, so AUTH_INSUFFICIENT_ROLE never applies to it. | #/components/schemas/ApiErrorResponseDto |
| 404 | No delivery with this event id belongs to the calling API client on this tenant. A delivery to a different API client, one on a different tenant, and one whose event type the calling client's Grant no longer covers are concealed behind this same response. | #/components/schemas/ApiErrorResponseDto |
| 429 | Rate limit exceeded. | #/components/schemas/ApiErrorResponseDto |
