# URL Decode
The `urldecode` processor specifies a list of fields to decode from URL encoded format. Under the `fields` key, each entry contains a `from: source-field` and a `to: target-field` pair, where:
- `from` is the source field name
- `to` is the target field name (defaults to the `from` value)

```yaml
processors:
  - urldecode:
      fields:
        - from: "field1"
          to: "field2"
      ignore_missing: false
      fail_on_error: true
```

In the example above:
- field1 is decoded in field2

The `urldecode` processor has the following configuration settings:
<definitions>
  <definition term="ignore_missing">
    (Optional) If set to true, no error is logged in case a key which should be URL-decoded is missing. Default is `false`.
  </definition>
  <definition term="fail_on_error">
    (Optional) If set to true, in case of an error the URL-decoding of fields is stopped and the original event is returned. If set to false, decoding continues also if an error happened during decoding. Default is `true`.
  </definition>
</definitions>
