# External alerts using External Issue Mapping

Learn more about collecting alerts from any external source using External Issue Mapping in Cortex XSIAM.

For a more complete and detailed picture of the activity involved in a case, Cortex XSIAM can ingest alerts from any external source. Cortex XSIAM stitches the external alerts together with relevant endpoint data and displays alerts from external sources in relevant cases and issues tables. You can also see external alerts and related artifacts and assets in causality views. For example, in the **Issues** table, right-click an issue and select **Investigate Causality Chain**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsiam/configure-cortex-xsiam/cortex-xsiam-data-sources/external-alerts-using-external-issue-mapping.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
