# Public API

Controls access to API key management for external integrations. This includes creating, viewing, editing, and revoking API keys that allow external systems to interact with Cortex XSIAM in Settings → Configurations → Integrations → API Keys. The Public API permissions also manage access to the Compute Unit Usage page.

### Error Handling

Any API call attempting to fetch, list, or modify stored secrets using a restricted key will return a 403 Forbidden error with an Insufficient permissions message. This ensures that automated workflows, scripts, and CLI interactions follow a strict least-privilege model.

| Permission | Description                                                                                                                                                                                                                                                                                                                               | Roles Example                                                                                                                                 |

| View       | The user can view the list of existing API keys but cannot create, edit, or delete them. The user can view the Compute Unit Usage page, but cannot edit the daily compute unit limit.                                                                                                                                                     | <ul><li>SOC Tier-2 and 3 Analysts: May need to verify API integrations.</li><li>Threat Hunter: Review API integrations for hunting.</li></ul> |
| View/Edit  | The user has full control over API keys, including creating, editing, and deleting them.

#### Required and recommended permissions

As API keys are often used to bridge data between modules, consider the following dependencies:

| Permission   | Permission Level | Reason                                                                                                     |
| ------------ | ---------------- | ---------------------------------------------------------------------------------------------------------- |
| Audit        | View             | Strongly recommended to track API key creation, modification, and deletion events for security compliance. |
| Integrations | View             | Recommended to understand which integrations use API keys for data collection.                             |
| Credentials  | View             | Recommended to view credentials that may be associated with API-based integrations.                        |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://cortex-docs.paloaltonetworks.com/cortex-xsiam/reference-and-developer-docs/role-based-access-control/configuration-permissions/public-api.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.
