# Vanilla JS SDK

For simple implementations that do not require a backend, you can use the Vanilla JS SDK. This SDK allows you to create user sessions in your game to securely interact with the Open Game Protocol API.

{% hint style="warning" %}
We **highly recommend** using the Server SDK, however, if using the Vanilla JS SDK, you should pair it with session restrictions to mitigate bots and malicious players from tampering with points submission.
{% endhint %}

### Requirements

* Creator Credentials from the [OGP Dashboard](https://app.opengameprotocol.com/dashboard)
* A registered game on the platform

## 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.opengameprotocol.com/build-on-og/open-game-sdk/vanilla-js-sdk.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.
