#Simple example to pull host details for a host within a member CID.
import json
from falconpy import api_complete as FalconSDK

#Create an instance of the class using a credential dictionary that contains our member_cid value
falcon = FalconSDK.APIHarness(creds={
        "client_id": "FALCON_API_ID_HERE",
        "client_secret": "FALCON_API_SECRET_HERE",
        "member_cid": "MEMBER_CID_HERE"
    }
)

#Forcibly authenticate using the command method to call the oAuth2AccessToken OperationID
#Set the result to be our new token
falcon.token = falcon.command('oauth2AccessToken', data=falcon.creds)["body"]["access_token"]

#Pull details from a host within the member CID to prove we're authenticated
host = falcon.command('GetDeviceDetails', ids="HOST_ID_HERE")

#Print the results
print(json.dumps(host, indent=4))
