M-Pesa PayPal Integration using Python

Introduction

M-Pesa is a popular mobile payment service in Kenya that allows users to send and receive money, pay bills, and purchase goods and services using their mobile phones. PayPal is a global payment system that allows users to make online payments, transfer money, and accept payments. In this tutorial, we will demonstrate how to integrate M-Pesa and PayPal using Python.

Requirements

• Python 3.x
• mpesa-python-sdk library: A Python wrapper for the M-Pesa API
• paypalrestsdk library: A Python wrapper for the PayPal API

Setup

• Install the mpesa-python-sdk and paypalrestsdk libraries using pip:

pip install mpesa-python-sdk paypalrestsdk

• Import the necessary modules:

from mpesa.api.client import MpesaApiClient
from paypalrestsdk import Payment

M-Pesa Integration

• Initialize the M-Pesa API client:

mpesa_client = MpesaApiClient(
    consumer_key='<your_mpesa_consumer_key>',
    consumer_secret='<your_mpesa_consumer_secret>',
    environment='sandbox'
)

• Create a function that will initiate an M-Pesa transaction:

def initiate_mpesa_transaction(amount, recipient):
    response = mpesa_client.initiate_payment(
        amount=amount,
        phone_number=recipient,
        reference='payment'
    )
    transaction_id = response['ConversationID']
    return transaction_id

PayPal Integration

• Initialize the PayPal API client:

paypal_client = paypalrestsdk.configure({
    'mode': 'sandbox',
    'client_id': '<your_paypal_client_id>',
    'client_secret': '<your_paypal_client_secret>'
})

• Create a function that will create a PayPal payment:

def create_paypal_payment(amount):
    payment = Payment({
        'intent': 'sale',
        'payer': {
            'payment_method': 'paypal'
        },
        'redirect_urls': {
            'return_url': '<your_return_url>',
            'cancel_url': '<your_cancel_url>'
        },
        'transactions': [{
            'amount': {
                'total': amount,
                'currency': 'USD'
            }
        }]
    })
    if payment.create():
        return payment.id
    else:
        return None

Integration

• Combine the M-Pesa and PayPal functions into a single function:

def initiate_payment(amount, recipient):
    mpesa_transaction_id = initiate_mpesa_transaction(amount, recipient)
    paypal_payment_id = create_paypal_payment(amount)
    return mpesa_transaction_id, paypal_payment_id

Conclusion

In this tutorial, we demonstrated how to integrate M-Pesa and PayPal using Python, using the mpesa-python-sdk and paypalrestsdk libraries. By combining the two, developers can enable their applications to accept mobile money payments and online payments from users.
