# API Keys

{% hint style="info" %}
You can read a bit more about how to use our GrpahQL API and read some examples [here](https://docs.ergonode.com/v/graphql-api/).
{% endhint %}

{% hint style="info" %}
Once a key is created it cannot be modified, so if you need to edit it, simply delete the old one and create a new one.
{% endhint %}

{% hint style="info" %}
It's possible to create an API key without a segment to include all products.
{% endhint %}

On the API Keys page, you’ll see an option to create a new API key. Click on it. You’ll be asked to provide some information for your new API key.

Type a key name, it can be anything. There is an option to limit products that will be available with this key to one of the [segments](/products/segments.md). By default for security reasons all keys are read-only, if you need a key with write access, tick the "Allow to write" checkbox.&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://usermanual.ergonode.com/system/settings/api-keys.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.
