When you have an API key, you can authenticate your requests to the IVX Cloud API by adding the feye-auth-key header to each request. The following is an example cURL request demonstrating the use of the auth header.
curl --location --request POST 'https://feapi.marketplace.apps.fireeye.com/files' \ --header 'feye-auth-key: eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...Mjg4NTk3NDh9.XuADzMOS0G-jOwmx9AVVudhsTxC7tUkEYBMQyj18kP0' \ --header 'Content-Type: multipart/form-data' \ --form 'file=@/Users/user/Downloads/malware.exe'
