Creating your first Stripe Charge with Python + Flask in 5 minutes

In this short series, we are going to look at how to create a charge to Stripe in a number of their officially supported languages!

Today, we are going to look at how to do so with Python and Flask.

The expectations are that you have both Python 3 and pip3 installed and have your Stripe API keys setup and ready to go.

Getting Started

1 2 3 4 5 6 mkdir python-flask-stripe && cd python-flask-stripe # pip or pip3 depending on env pip3 install Flask pip3 install stripe pip3 install -U python-dotenv touch .env server.py

Setting up .env

Fetch your keys from Stripe and replace the following in the file:

1 SK_TEST_KEY=sk... # replace sk...

Writing server.py

Set up the file to look like the following:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 from flask import Flask from flask import request from dotenv import load_dotenv import stripe import os # Load local .env file and assign key load_dotenv() stripe.api_key = os.environ.get("SK_TEST_KEY") app = Flask(__name__) @app.route("/api/charge", methods = ['POST']) def charge(): try: content = request.get_json() # Print what JSON comes in for the sake of checking print(content) resp = stripe.Charge.create( amount=content['amount'], currency="usd", source="tok_visa", receipt_email=content['receiptEmail'], ) print("Success: %r" % (resp)) return "Successfully charged", 201 except Exception as e: print(e) return "Charge failed", 500 if __name__ == "__main__": app.run()

The above:

  1. Fetches and sets OS env from .env file.
  2. Sets the Stripe API key.
  3. Sets a route /api/charge that only takes the POST method and creates a charge based on the amount we pass.

Running the server

python3 server.py will start the server on port 5000.

Running http POST http://localhost:5000/api/charge amount:=1700 receiptEmail=hello_flask@example.com (using HTTPie) will come back with success. Check your Stripe dashboard and you will see a charge made for AUD\$17.00! Hooray!

I chose to use HTTPie because I feel it is a fun tool that more should know about! Alternative, you could do the above using curl as well (or anything that can make a POST request for a matter of fact).

1 2 3 4 curl --header "Content-Type: application/json" \ --request POST \ --data '{"amount":1700,"receiptEmail":"hello_flask@example.com"}' \ http://localhost:5000/api/charge
