# Confirm a signing secret rotation (beta)

`POST /api/v1/connections/{connection_id}/trigger-ingress/signing-secret/confirm`

This endpoint is in beta. Its request and response may change.

Retires the previous signing secret, so only the new one is accepted. Call it once the app signs with the new secret. Pass `signing_secret_rotation_id` from the latest set or get response, so you confirm the rotation you checked. With no rotation in progress, the call succeeds and changes nothing.

**Path parameters**

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `connection_id` | string | Yes | ID of the connection, in this environment. Up to 64 characters. |

**Request body**

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `signing_secret_rotation_id` | string | No | The rotation to confirm: the signing_secret_rotation_id from the latest [Set a signing secret](https://docs.scalekit.com/agentkit/reference/triggers/set-a-signing-secret/) or [Get a webhook URL](https://docs.scalekit.com/agentkit/reference/triggers/get-a-webhook-url/) response. Required while a rotation is in progress; a missing or non-matching value is then refused with 400, rather than confirming a rotation you did not look at. Ignored when no rotation is in progress. |

**Response (200)**

| Name | Type | Description |
| --- | --- | --- |
| `connection_id` | string | ID of the connection this webhook URL belongs to. |
| `id` | string | Unique identifier of the connection's webhook endpoint. |
| `masked_signing_secret` | string | The stored secret with all but its last four characters replaced, or every character replaced for a secret of 8 characters or fewer. Empty when none is configured. Enough to compare against the secret the provider's app configuration shows, and never enough to sign with. |
| `previous_signing_secret_expires_at` | string | When the previous secret stops being accepted even if the rotation is never confirmed: 24 hours after the rotation started. Absent when no rotation is in progress. |
| `rotation_in_progress` | boolean | Whether the previous signing secret is still accepted alongside the current one. True from the moment a different secret replaces a stored one until the rotation is confirmed, or until previous_signing_secret_expires_at passes. |
| `signing_secret_configured` | boolean | Whether a signing secret is stored. While false, every event sent to the URL is answered with 503 so the provider retries it, and the provider's own URL verification fails. |
| `signing_secret_rotation_id` | string | Identifies the latest signing-secret rotation; it increases by one each time a rotation starts. Zero when none has ever started. Pass this value to [Confirm a signing secret rotation](https://docs.scalekit.com/agentkit/reference/triggers/confirm-a-signing-secret-rotation/) to confirm this specific rotation. A value naming a rotation that a newer one has since replaced is refused rather than confirming the wrong rotation. |
| `url` | string | The URL to paste into the provider's app configuration as the event destination. It is built on your environment's domain, using its custom domain when one is set, and ends in a random token unique to this connection, so treat it as confidential. Returned whether or not a signing secret has been set. The URL accepts request bodies up to 1 MB and answers a larger one with 413. Until a signing secret is set it answers events with 503, so the provider retries them; an event that fails signature verification is answered with 400. |

**Errors**

- `400`: Invalid request - connection_id is not a valid connection ID, or a rotation is in progress and signing_secret_rotation_id is missing or does not match it, for example because a newer rotation has started. The message names the current rotation ID; read the endpoint again with [Get a webhook URL](https://docs.scalekit.com/agentkit/reference/triggers/get-a-webhook-url/) before confirming
- `404`: Not found - no webhook URL has been created for this connection yet (error_code TRIGGER_INGRESS_ENDPOINT_NOT_CREATED; call [Create a webhook URL](https://docs.scalekit.com/agentkit/reference/triggers/create-a-webhook-url/) first), the connection does not exist in this environment (error_code RESOURCE_NOT_FOUND), or Triggers isn't turned on for your environment (error_code RESOURCE_NOT_FOUND)
- `500`: Internal error - the rotation could not be confirmed; retry the request

**Request**

```bash
curl -sS -X POST \
  "$SCALEKIT_ENVIRONMENT_URL/api/v1/connections/conn_133400101014997214/trigger-ingress/signing-secret/confirm" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "signing_secret_rotation_id": "1"
  }'
```

**Response**

```json
{
  "id": "tie_149528599802678310",
  "connection_id": "conn_133400101014997214",
  "url": "https://your-env.scalekit.dev/triggers/v1/q7Rk2mVx9TbL4nWc8YpZ3s",
  "signing_secret_configured": true,
  "masked_signing_secret": "****************************a4f9",
  "rotation_in_progress": false,
  "signing_secret_rotation_id": "1"
}
```

**Python SDK:** `scalekit_client.actions.triggers.confirm_signing_secret_rotation`

Finish a signing-secret rotation so only the new secret is accepted.

```python
scalekit_client.actions.triggers.confirm_signing_secret_rotation(
    connection_id: str,
    signing_secret_rotation_id: int | None = None,
) -> TriggerIngressEndpoint
```

Example:

```python
result = scalekit_client.actions.triggers.confirm_signing_secret_rotation(
    connection_id="conn_133400101014997214",
    signing_secret_rotation_id=1,
)
```

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `connection_id` | `str` | Yes | The connection (`conn_...`). |
| `signing_secret_rotation_id` | `int \| None` | No | `TriggerIngressEndpoint.signing_secret_rotation_id` of the rotation to confirm. Required while a rotation is in progress; ignored when none is. |

Returns `TriggerIngressEndpoint`: The endpoint after the confirmation.
