To build on tbicr's answer, here's an example overriding the register method example:

from flask import Blueprint

auth = None

class RegisteringExampleBlueprint(Blueprint):
    def register(self, app, options, first_registration=False):
        global auth

        config = app.config
        client_id = config.get('CLIENT_ID')
        client_secret = config.get('CLIENT_SECRET')
        scope = config.get('SCOPE')
        callback = config.get('CALLBACK')

        auth = OauthAdapter(client_id, client_secret, scope, callback)

        super(RegisteringExampleBlueprint,
              self).register(app, options, first_registration)

the_blueprint = RegisteringExampleBlueprint('example', __name__)

And an example using the record decorator:

from flask import Blueprint
from api import api_blueprint as api

auth = None

# Note there's also a record_once decorator
@api.record
def record_auth(setup_state):
    global auth

    config = setup_state.app.config
    client_id = config.get('CLIENT_ID')
    client_secret = config.get('CLIENT_SECRET')
    scope = config.get('SCOPE')
    callback = config.get('CALLBACK')

    auth = OauthAdapter(client_id, client_secret, scope, callback)
