# OCPI Version Support 2.1.1, 2.2.1, and 2.3.0

ENAPI supports three OCPI versions. Our translation engine handles the differences automatically, so partners on different versions can still roam with each other.

Adds hub support, richer tariffs, role-based endpoints.</td></tr><tr><td><strong>2.3.0</strong></td><td>Recommended</td><td>Latest. Improved credential management and session handling. Native HGV and PnC support. </td></tr></tbody></table>

**Note:** OCPI 2.2 (without the .1 patch) is not supported.

### Which version should I use?

If you're starting fresh, we recommend **2.2.1 or higher**.

If you already have a working 2.1.1 implementation, you don't need to upgrade. Our translation engine handles version differences between you and your partners — you can connect on 2.1.1 and roam with a partner on 2.3.0 without either side doing anything special.

## 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://docs.enapi.com/technical-documentation/ocpi-version-support-2.1.1-2.2.1-and-2.3.0.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.
