# List webhook delivery attempts

Source: https://joinsimplesms.com/docs/api/webhooks/list-deliveries
Index: https://joinsimplesms.com/llms.txt

`GET /v1/webhooks/deliveries`

Every attempt to push an event to your endpoints, newest first, kept 30 days: status code, latency, attempt number and the first 2 KB of the response body.

Send your API key as a bearer token: `Authorization: Bearer ssms_sk_...`. Test keys run this endpoint against the [sandbox](/docs/sandbox); see [Authentication](/docs/authentication) for key modes and scopes.

## Query parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `endpoint_id` | string | No |  |
| `event_id` | string | No | Every attempt for one event |
| `limit` | integer | No | Default 25. Maximum 100. |
| `cursor` | string | No |  |

Results are paged. When `has_more` is true, pass `next_cursor` from the response as `cursor` to fetch the next page.

## Responses

| Status | Meaning | Body |
| --- | --- | --- |
| 200 | Deliveries, newest first | Page of `WebhookDelivery` |
| 401 | Missing, malformed, or revoked API key | `Error` |
| 402 | Billable live calls only: the prepaid credit balance cannot cover the call (insufficient_credits); nothing was done or charged | `Error` |
| 404 | No such endpoint | `Error` |
| 429 | Rate limit or quota exceeded | `Error` |

### 200: each item in `data` (WebhookDelivery)

The body is a page: `data` (the array), `has_more`, and `next_cursor` (null on the last page).

| `latency_ms` | integer |  |
| `response_body` | string | First 2 KB of what your endpoint answered Nullable. |

## Errors

| Status | When |
| --- | --- |
| 401 | Missing, malformed, or revoked API key |
| 402 | Billable live calls only: the prepaid credit balance cannot cover the call (insufficient_credits); nothing was done or charged |

Every error has the same JSON shape, and `request_id` matches the `X-Request-Id` response header. [Errors](/docs/errors) lists every code and what to do about it.

```json
{
  "error": {
    "code": "invalid_request",
    "message": "What went wrong, in plain words.",
    "param": "the_field",
    "request_id": "req_a1B2c3D4e5F6g7H8"
  }
}
```

## Examples

### curl

```bash
curl -X GET "https://api.joinsimplesms.com/v1/webhooks/deliveries?limit=10" \
  -H "Authorization: Bearer $SIMPLESMS_API_KEY"
```

### Node.js

The Node.js SDK does not wrap this endpoint yet; call it with `fetch`.

```javascript
const res = await fetch('https://api.joinsimplesms.com/v1/webhooks/deliveries?limit=10', {
  method: 'GET',
  headers: {
    Authorization: `Bearer ${process.env.SIMPLESMS_API_KEY}`,
  },
});

if (!res.ok) throw new Error((await res.json()).error.message);
const data = await res.json();
```

### Python

The Python SDK does not wrap this endpoint yet; call it over HTTP.

```python
import json, os, urllib.request

req = urllib.request.Request(
    "https://api.joinsimplesms.com/v1/webhooks/deliveries?limit=10",
    method="GET",
    headers={
        "Authorization": f"Bearer {os.environ['SIMPLESMS_API_KEY']}",
    },
)
with urllib.request.urlopen(req) as res:
    data = json.load(res)
```
