Where do I find the access token? When I pass in x-airbnb-api-key, I get the verification error when try to initialise API

I try to run this:

api = airbnb.Api(access_token='access token')

But I am unable to locate the access token. THe only thing I could get from webdev tools in browser when logging in to airbnb is the API key but then I get the verification error. Anyone could explain where I can get access_token=`<ACCESS_TOKEN_OBTAINED_ON_LOGIN>`???
