# Building your own pluggable SerDe

### Custom pluggable serde registration

You can implement your serde and register it in the UI. To do so:

1. Add `serde-api` dependency, [link to maven central](https://central.sonatype.com/artifact/io.kafbat.ui/serde-api)
2. Implement `io.kafbat.ui.serde.api.Serde` interface. See javadoc for implementation requirements.
3. Pack your serde into an uber jar, or provide a directory with no-dependency jar and its dependencies jars

Example pluggable serdes : [kafka-smile-serde](https://github.com/kafbat/ui-serde-smile), [kafka-glue-sr-serde](https://github.com/kafbat/ui-serde-glue)

Sample configuration:

```yaml
kafka:
  clusters:
    - name: Cluster1
      serde:
        - name: MyCustomSerde
          className: my.lovely.org.KafkaUiSerde
          filePath: /var/lib/kui-serde/my-kui-serde.jar
          
        - name: MyCustomSerde2
          className: my.lovely.org.KafkaUiSerde2
          filePath: /var/lib/kui-serde2
          properties:
            prop1: v1
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ui.docs.kafbat.io/configuration/serialization-serde/pluggable-serdes/building-your-own-pluggable-serde.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
