# Interface: ApiLogEventParams

Defined in: [core/query/logparams.ts:30](https://github.com/BearBin1215/types-mediawiki-response/blob/c1e25ea2ef2684b43c79e05d6e0dd36e33fbc9a3/src/core/query/logparams.ts#L30)

Structured log details — the `params` object of a log event (`leprop=details`
on `list=logevents`, `logparams` under the log-info fields of
`list=recentchanges` / `list=watchlist`).

Each log action writes its own key set, which the server normalizes for the
API. The keys below are the ones MediaWiki core itself writes; which of
them a row carries depends on its `type`/`action`.

The key space is open: extensions and site configuration can register
further log actions, and rows written by older MediaWiki versions keep
their historical key forms. Unknown keys therefore fall back to `unknown`
instead of erroring. Consumers targeting one specific log action — or a
site-custom one — can add its keys through interface merging:

## Example

```ts
declare module "types-mediawiki-response" {
  interface ApiLogEventParams {
    // a site-custom log action, or a legacy key form still in the data
    "4::target"?: string;
  }
}
```

## Indexable

> \[`key`: `string`]: `unknown`

Any other parameter a log action attaches — a log action registered by an
extension or site configuration, or a legacy key form on rows written by
an older MediaWiki version.
