Python Flask and the Force.com REST API: Simple simple-salesforce example

salesforce.py

from flask import Flask, redirect, request
import requests

from simple_salesforce import Salesforce

consumer_key = 'your_consumer_key'
consumer_secret = 'your_consumer_secret'
access_token_url = 'https://login.salesforce.com/services/oauth2/token'
redirect_uri = 'http://localhost:5000/callback'
authorize_url = 'https://login.salesforce.com/services/oauth2/authorize'
app = Flask(__name__)

@app.route('/login')
def login():
    url = "%s?response_type=code&client_id=%s&redirect_uri=%s" % (authorize_url, consumer_key, redirect_uri)
    return redirect(url)


@app.route('/callback')
def callback():
    code = request.args.get('code')
    data = {
        'grant_type': 'authorization_code',
        'redirect_uri': redirect_uri,
        'code': code,
        'client_id': consumer_key,
        'client_secret': consumer_secret
    }
    headers = {
        'content-type': 'application/x-www-form-urlencoded'
    }
    req = requests.post(access_token_url, data=data, headers=headers)
    response = req.json()

    sf = Salesforce(instance_url=response['instance_url'], session_id=response['access_token'])

    #Now you can make your calls to the Salesforce api using the sf object. For more information: https://github.com/simple-salesforce/simple-salesforce


    return "ok, connected to Salesforce"
