# Splunk credentials
You can use these credentials to authenticate the following nodes:
* [Splunk](/integrations/builtin/app-nodes/n8n-nodes-base.splunk.md)
## Prerequisites
* [Download and install](https://www.splunk.com/en_us/download/splunk-enterprise.html) Splunk Enterprise.
* [Enable token authentication](https://docs.splunk.com/Documentation/Splunk/9.2.1/Security/EnableTokenAuth) in **Settings > Tokens**.

**Free trial Splunk Cloud Platform accounts can't access the REST API**
Free trial Splunk Cloud Platform accounts don't have access to the REST API. Ensure you have the necessary permissions. Refer to [Access requirements and limitations for the Splunk Cloud Platform REST API](https://docs.splunk.com/Documentation/SplunkCloud/8.2.2203/RESTTUT/RESTandCloud) for more details.
{% endhint %}
## Supported authentication methods
* API auth token
## Related resources
Refer to [Splunk's Enterprise API documentation](https://docs.splunk.com/Documentation/Splunk/latest/RESTREF/RESTprolog) for more information about the service.
## Using API auth token
To configure this credential, you'll need:
* An **Auth Token**: Once you've enabled token authentication, create an auth token in **Settings > Tokens**. Refer to [Creating authentication tokens](https://docs.splunk.com/Documentation/Splunk/9.2.1/Security/CreateAuthTokens) for more information.
* A **Base URL**: For your Splunk instance. This should include the protocol, domain, and port, for example: `https://localhost:8089`.
* **Allow Self-Signed Certificates**: If turned on, n8n will connect even if SSL validation fails.
## Required capabilities
Your Splunk platform account and role must have certain capabilities to create authentication tokens:
* `edit_tokens_own`: Required if you want to create tokens for yourself.
* `edit_tokens_all`: Required if you want to create tokens for any user on the instance.
Refer to [Define roles on the Splunk platform with capabilities](https://docs.splunk.com/Documentation/Splunk/9.2.1/Security/Rolesandcapabilities) 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/splunk.md?ask=&goal=
```
`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.
