# 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**.
