Before you can begin using Cortex XSIAM APIs, you must generate the following items in Cortex XSIAM:
| Value | Description |
|---|---|
| API Key | The API Key is your unique identifier used as the Authorization:{key} header required for authenticating API calls. Depending on your desired security level, you can generate two types of API keys, Advanced or Standard, from Cortex XSIAM. |
| API Key ID | The API Key ID is your unique token used to authenticate the API Key. The header used when running an API call is x-xdr-auth-id:{key_id}. |
| FQDN | The FQDN is a unique host and domain name associated with each tenant. |
Cortex XSIAM API URIs are made up of your tenant's FQDN, the API name, and endpoint path. For example, https://api-{fqdn}/xsiam/public/v1/{endpoint_path}/.
The following steps describe how to generate the necessary key values and run your first API call:
