Can I have a simplest Api usage example

[sftranna]

hi there,
I am working on an app.
I have tried to call an Api but this never authenticate the credentials provided in the code rather at console this asks for credentials like "what is the ip of qradar console required to make this Api call" and username password and stored these in a flat file at C:......\administrator.qradar_appfw.auth

Here is the code for calling an api
Username='ABC'
Pwd='cuz'
Ip='xxx.xxx.xxx.xxx'
userpass=username + ':' + pwd
Encodecred= b"Basic "+base64.b64encode(userpass.encode('ascii'))
headers = {'SEC': 'ABSBDHDJDJDJJDJDJDJ'}
headers = {'Authorization': Encodecred}
xurl = 'https://'+Ip+'api/endpoint'
reaponse=qpylib.Rest('GET', xurl, headers = headers)

Plz guide me about the problem so that I can verify credentials through code password or SEC but not from .qradar_appfw.auth.
Thanks in advance

Can you plz provide a simplest working example with a basic tutorial mentioning all the step (like getting authorization code, ssl certificate and all that) required before running that code?
I have done a lot of R&D but failed.

Thanks
