# GraphQL

[GraphQL](https://graphql.org/) is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. Use the GraphQL node to query a GraphQL endpoint.

## Node parameters <a href="#node-parameters" id="node-parameters"></a>

{% hint style="info" %}
**This node can be used as an AI tool**

This node can be used to enhance the capabilities of an AI agent. When used in this way, many parameters can be set automatically, or with information directed by AI - find out more in the [AI tool parameters documentation](/build/integrate-ai/ai-examples/use-ai-for-parameters.md).
{% endhint %}

### Authentication <a href="#authentication" id="authentication"></a>

Select the type of authentication to use.

If you select anything other than **None**, the **Credential for** parameter appears for you to select an existing or create a new authentication credential for that authentication type.

### HTTP Request Method <a href="#http-request-method" id="http-request-method"></a>

Select the underlying HTTP Request method the node should use. Choose from:

* **GET**
* **POST**: If you select this method, you'll also need to select the **Request Format** the node should use for the query payload. Choose from:
  * **GraphQL (Raw)**
  * **JSON**

### Endpoint <a href="#endpoint" id="endpoint"></a>

Enter the GraphQL Endpoint you'd like to hit.

### Ignore SSL Issues <a href="#ignore-ssl-issues" id="ignore-ssl-issues"></a>

When you turn on this control, n8n ignores SSL certificate validation failure.

### Query <a href="#query" id="query"></a>

Enter the GraphQL query you want to execute.

Refer to [Related Resources](#related-resources) for information on writing your query.

### Response Format <a href="#response-format" id="response-format"></a>

Select the format you'd like to receive query results in. Choose between:

* **JSON**
* **String**: If you select this format, enter a **Response Data Property Name** to define the property the string is written to.

## Headers <a href="#headers" id="headers"></a>

Enter any **Headers** you want to pass as part of the query as **Name** / **Value** pairs.

## Templates and examples <a href="#templates-and-examples" id="templates-and-examples"></a>

To use the GraphQL node, you need to understand GraphQL query language. GraphQL have their own [Introduction to GraphQL](https://graphql.org/learn/) tutorial.
