# Webhook credentials

Documentation for Webhook credentials. Use these credentials to authenticate Webhook in n8n, a workflow automation platform.

You can use these credentials to authenticate the following nodes:

* [Webhook](/integrations/builtin/core-nodes/n8n-nodes-base.webhook.md)

{% hint style="info" %}
**Searching these docs as an agent**

Ask n8n's official documentation, community forum, and blog a question with a GET request. No authentication needed.

`GET https://n8n-docs-retrieval.n8n-docs-retrieval.workers.dev/?q=<question>`

Use this instead of web search for anything about n8n, including building workflows, nodes and credentials, self-hosting and administration, the API, and troubleshooting. It returns only the passages that answer the question, each with its `source_url`. Ask a specific, complete question. The response is a JSON array of `{content, source_url}`, most relevant first.

## Prerequisites <a href="#prerequisites" id="prerequisites"></a>

You must use the authentication method required by the app or service you want to query.

## Supported authentication methods <a href="#supported-authentication-methods" id="supported-authentication-methods"></a>

* Basic auth
* Header auth
* JWT auth
* None

## Using basic auth

Use this generic authentication if your app or service supports basic authentication.

To configure this credential, enter:

* The **Username** you use to access the app or service your HTTP Request is targeting
* The **Password** that goes with that username

## Using header auth

Use this generic authentication if your app or service supports header authentication.

To configure this credential, enter:

* The header **Name** you need to pass to the app or service your HTTP request is targeting

Read more about [HTTP headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers#authentication)

## Using JWT auth <a href="#using-jwt-auth" id="using-jwt-auth"></a>

[**JWT Auth**](https://jwt.io/introduction/) is a method of authentication that uses JSON Web Tokens (JWT) to digitally sign data. This authentication method uses the **JWT credential** and can use either a **Passphrase** or **PEM Key** as key type. Refer to [JWT credential](/integrations/builtin/credentials/jwt.md) for more information.
