Setting up

In order to get set up, you are going to need to clone this repository. After that, set up a virtualenv and satisfy the requirements by running pip install -r requirements.txt. (please make sure you're in the root directory when you run pip install). Additional explanation can be found on the Flask quickstart and documentation.

Code samples

Find some code samples below.

Routing & handling

Include handler function.

# Include the handler function(s)
from handlers.pollfish_handler import verify

Setup routing.

@app.route('/webhooks/pollfish-s2s')
def verify_survey():
    return verify()

Query strings in handler function

Get the arguments from the Pollfish request query strings. You should have defined those in your application / dashboard.

Flask has an easy function for getting and parsing query strings: request.args.get()

from flask import request

def verify():
    device_id = request.args.get('device_id')
    cpa = request.args.get('cpa')
    request_uuid = request.args.get('request_uuid')
    timestamp = request.args.get('timestamp')
    tx_id = request.args.get('tx_id')
