# List Notification Deliveries

> Page delivery attempts for one run. Use notification_configurations for effective configuration. Delivery without a recorded receipt is unknown; run completion does not prove Slack posting. Email acceptance is not proof of inbox delivery or reading.

Required scope: `agent_runs:read`. See [API key permissions](/api/api-key-scopes) and the [pipeline dashboard guide](/api/observability/overview).

## Request

```bash theme={null}
curl "https://api.mosaic.so/agent_run/44444444-4444-4444-8444-444444444444/notifications?limit=25" \
  -H "Authorization: Bearer mk_your_api_key" \
  -H "X-Workspace-Id: 66666666-6666-4666-8666-666666666666"
```

Workspace IDs and resource IDs above are examples. Use IDs returned by your own API calls.

## Parameters

| Parameter | Location | Meaning |
| - | - | - |
| `limit` | query | Page size from 1 to 100; default 25. Progress and notification configuration pages count tiles. |
| `cursor` | query | Opaque next\_cursor from the previous page. Pass verbatim and preserve the original filters. Do not decode or construct it. |
| `from` | query | Inclusive ISO 8601 lower bound on creation time. |
| `to` | query | Inclusive ISO 8601 upper bound on creation time. |
| `updated_from` | query | Inclusive ISO 8601 update watermark. Restart pagination on each poll and fetch every page before advancing it. |
| `workspace_id` | query | Optional workspace UUID within the key organization. Must match X-Workspace-Id when both are supplied. |
| `event` | query | on\_start, on\_complete, or on\_error. |
| `channel` | query | slack or email. |
| `status` | query | Exact persisted status; for example pending for events or open for batches. |
| `node_id` | query | Runtime tile UUID; not the template tile ID. |
| `run_id` | path | run id UUID. |
| `X-Workspace-Id` | header | Restrict requests to an authorized workspace UUID. Omit to query the organization. |

## Deliveries values

| Field | Meaning |
| - | - |
| `id` | Delivery attempt ID. |
| `agent_node_id` | Runtime tile ID. |
| `event` | See nested schema in the API reference. |
| `channel` | See nested schema in the API reference. |
| `status` | Persisted delivery status. delivered requires confirmed Slack root-message acceptance or all intended email recipients accepted; partial email delivery is failed. |
| `destination_id` | Slack channel ID; null for email. Email addresses are not returned. |
| `provider_message_id` | Slack message timestamp when confirmed; may be null. |
| `error_message` | Delivery error details. Partial email failures use a summary without recipient addresses. |
| `created_at` | Attempt creation time. |
| `updated_at` | Attempt status update time. |
| `delivered_at` | Confirmed provider acceptance time, when available. |

When `next_cursor` is non-null, request the next page with the same filters and that cursor. `limit` defaults to 25 and is capped at 100. Read the [polling and error-handling guidance](/api/observability/overview#poll-without-losing-updates) before building a dashboard.
