To allow remote CORS requests on your web service api, you can simply initialize your flask restful API like this:

from flask import Flask
from flask_restful import reqparse, abort, Api, Resource
from flask_cors import CORS

app = Flask(__name__)
cors = CORS(app, resources={r"*": {"origins": "*"}})
api = Api(app)

This adds the CORS header to your api instance and allows a CORS request on every path from every origin.
