# ServiceNow credentials

You can use these credentials to authenticate the following nodes:

* [ServiceNow](/integrations/builtin/app-nodes/n8n-nodes-base.servicenow.md)

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

Create a [ServiceNow](https://developer.servicenow.com/dev.do#!/reference) developer account.

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

* Basic auth
* OAuth2

## Related resources <a href="#related-resources" id="related-resources"></a>

Refer to [ServiceNow's API documentation](https://developer.servicenow.com/dev.do#!/reference/api/washingtondc/rest/) for more information about the service.

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

To configure this credential, you'll need:

* A **User** name: Enter your ServiceNow username.
* A **Password**: Enter your ServiceNow password.
* A **Subdomain**: The subdomain for your servicenow instance is in your instance URL: `https://<subdomain>.service-now.com/`. For example, if the full URL is `https://dev99890.service-now.com`, then the subdomain is `dev99890`.

## Using OAuth2 <a href="#using-oauth2" id="using-oauth2"></a>

To configure this credential, you'll need:

* A **Client ID**: Generated once you register a new app.
* A **Client Secret**: Generated once you register a new app.
* A **Subdomain**: The subdomain for your servicenow instance is in your instance URL: `https://<subdomain>.service-now.com/`. For example, if the full URL is `https://dev99890.service-now.com`, then the subdomain is `dev99890`.

To generate your **Client ID** and **Client Secret**, register a new app in **System OAuth > Application Registry > New > Create an OAuth API endpoint for external clients**. Use these settings for your app:

* Copy the **Client ID** and add it to your n8n credential.
* Enter a **Client Secret** or leave it blank to automatically generate a random secret. Add this secret to your n8n credential.
* Copy the n8n **OAuth Redirect URL** and add it as a **Redirect URL**.

Refer to [How to setup OAuth2 authentication for RESTMessageV2 integrations](https://www.servicenow.com/community/in-other-news/how-to-setup-oauth2-authentication-for-restmessagev2/ba-p/2271823) for more information.

## 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.n8n.io/integrations/builtin/credentials/servicenow.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.
