You can integrate your Trellix environment with a Marketplace App by creating a new configuration that uses an API Key for authentication.
Assign a Name for the configuration.
In the HTTP tab, set the Authentication settings:
URL: Enter the API endpoint: https://feapi.marketplace.apps.fireeye.com.
Auth Type: Select API Key.
Key: Enter the header key: feye-auth-key.
Value: Enter the API Key value for authentication.
Key Placement: Select Header.
Click Next.
In the Edge tab, select the required Edge (e.g., trellix-default).
To find available Edges, click the Auto Detect button.
Click Save.
You can add another configuration for the app by repeating these steps.
