# Event Log API

Learn about the APIs for searching and retrieving event logs.

> **VERSION:** Available since `1.6.0`

The Event Log contains messages that are not easy to convey to user at runtime - logs and errors from asynchronous code execution. These messages include:

*   SMTP transport errors
*   Lambda execution exceptions
*   Lambda execution console logs
*   SAML IdP integration errors and debug
*   Webhook event errors
*   Runtime exceptions due to email template rendering issues

This page contains the APIs that are used to retrieve Event Logs. Here are the APIs:

## Retrieve an Event Log

### Request

[Global API Key Authentication](https://fusionauth.io/docs/apis/authentication.md#global-api-key-authentication)

Retrieve an Event Log by Id

`GET /api/system/event-log/{logId}`

#### Request Parameters

`logId`

*   Long
*   required

The unique Id of the Event Log to retrieve.

### Response

*Response Codes*

`GET /api/system/event-log/search?message={message}&start={start}&end={end}&type={type}?message={message}&start={start}&end={end}&type={type}`

When calling the API using a `GET` request you will send the search criteria on the URL using request parameters. In order to simplify the example URL above, not every possible parameter is shown, however using the provided pattern you may add any of the documented request parameters to the URL.

#### Request Parameters

The number of results to return from the search.

`orderBy`

*   `insertUser` - the user that create the Event Log
*   `message` - the message of the Event Log
