# HTTP API overview for Webhook Debugger & Logger

> Full HTTP API surface for Webhook Debugger & Logger: base URLs, all endpoints at a glance, authentication model, and runtime discovery via /info.

The Webhook Debugger & Logger exposes a compact HTTP API for capturing incoming webhook traffic, querying and replaying stored events, streaming live activity, and probing the service's health. All endpoints are available from the same base URL, whether you are running on Apify or self-hosting on `localhost:8080`.

## Base URL

<CodeGroup>
  ```text Apify hosted theme={null}
  https://<run-id>.runs.apify.net
  ```

  ```text Self-hosted theme={null}
  http://localhost:8080
  ```
</CodeGroup>

Replace `<run-id>` with the identifier of your Apify run. When self-hosting with Docker or Node.js directly, the server binds to port `8080` by default. You can override the port with the `ACTOR_WEB_SERVER_PORT` environment variable.

## Endpoints

| Method | Path                         | Description                                               |
| ------ | ---------------------------- | --------------------------------------------------------- |
| `GET`  | `/`                          | Built-in dashboard page (HTML or plain-text summary)      |
| `GET`  | `/info`                      | Runtime metadata, active webhooks, and endpoint discovery |
| `ANY`  | `/webhook/:id`               | Capture incoming webhook traffic for any HTTP method      |
| `GET`  | `/logs`                      | Query captured events with filtering and pagination       |
| `GET`  | `/logs/:logId`               | Fetch a single captured event by ID                       |
| `GET`  | `/logs/:logId/payload`       | Retrieve the raw payload for a captured event             |
| `GET`  | `/log-stream`                | Server-Sent Events live feed of captured events           |
| `POST` | `/replay/:webhookId/:itemId` | Replay a captured event to a new destination URL          |
| `GET`  | `/system/metrics`            | Dataset-to-DuckDB sync service metrics                    |
| `GET`  | `/health`                    | Liveness probe                                            |
| `GET`  | `/ready`                     | Readiness probe                                           |

## Runtime endpoint discovery

You can discover the full set of live endpoint URLs at runtime by calling [`GET /info`](/api-reference/info). The response includes an `endpoints` map with fully-qualified URLs built from the running base URL, so you do not need to hard-code paths when integrating programmatically.

## Authentication

Authentication is **optional**. When you supply an `authKey` in the Actor input, management endpoints and (optionally) webhook ingest require that key via a Bearer token header or `?key=` query parameter. The `/health` and `/ready` probes are never protected. See [Authentication](/api-reference/authentication) for full details.
