Flask-SimplePay 0.11

OTP SimplePay payment extension for Flask

Flask-SimplePay

OTP SimplePay integration with Flask

Usage

Initialize the extension with Flask and Flask-SQLAlchemy instances.

from flask import Flask
from flask_simplepay import SimplePay
from flask_sqlalchemy import SQLAlchemy


app = Flask(__name__)
db = SQLAlchemy(app)
simple = SimplePay(app, db)
    

if __name__ == '__main__':
    app.run()

To start payment, a Transaction is needed. After adding the transaction and commiting the session, the /simple/start/<int:transaction_id> endpoint starts the payment procedure. When the payment process is finished, the /simple/back endpoint is called. To define what behaviour, extend the TransactionMixin class and override the back() method. Return value should be anything a Flask route method would return.

from flask import render_template
from flask_simplepay import TransactionMixin


class Transaction(db.Model, TransactionMixin):
    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    
    def back(self):
        return render_template({self.result}, transaction=self)

The Transaction method should be provided at initialization as transaction_class argument.
