Flutterwave Payment Redirect Integration into Django-Oscar

[Tunde Ojo]

Good day all,

I have been grappling with the problem of integrating the flutterwave API into my Django-Oscar project.

I have forked the checkout app and I am attempting to override the PaymentDetailsView in checkout.views.py as shown below:

from oscar.apps import checkout

from oscar.apps.checkout import session, views

from oscar.apps.checkout.forms import User

from oscar.apps.payment import models

from oscar.apps.payment.exceptions import *

import requests

import datetime

import os

from requests.api import request

import json

FLUTTERWAVE_SECRET_KEY = os.environ.get('FLUTTERWAVE_SECRET_KEY')

url = "https://api.flutterwave.com/v3/payments"

a='Bearer ' + FLUTTERWAVE_SECRET_KEY

# Subclass the core Oscar view so we can customise

class PaymentDetailsView(views.PaymentDetailsView):

    def handle_payment(self, order_number, total, **kwargs):

        # Talk to payment gateway.  If unsuccessful/error, raise a

        # PaymentError exception which we allow to percolate up to be caught

        # and handled by the core PaymentDetailsView.

       

        # Hardcode the para variable for a dictionary. I will like to get the 

        para = {"tx_ref":"hooli-tx-1920bbtytty", "amount":"100", "currency":"NGN", 

                "redirect_url":"https://webhook.site/9d0b00ba-9a69-44fa-a43d-a82c33c36fdc", 

                "customer.email":"ba****@yahoo.com"} # temporary, not perfect

             

        response2=requests.post(url, para, headers={'Authorization': a}) 

        

        # the response is in the following form {"status":"success","message":"Hosted Link",

        # "data":{"link":"https://checkout.flutterwave.com/v3/hosted/pay/39b54380fa7d20bbdf14"}}

        # extract the text part of the response in string format

        response2_text = response2.text

        

        # convert the extracted text from response to json

        response2_json = json.loads(response2_text)

        # Get the data and link part from the response_json

        pay_url = response2_json.get("data").get("link")

        # Redirect to the pay_url link returned as link in response to bring up the 

        # flutterwave modal so that customer can enter make payment

        raise RedirectRequired(pay_url)

Instead of hard-coding the para dictionary, how can I get the dynamic vlaues such as email, basket totals_incl_tax and my tr_ref which I believe is the order_no.

I will like some help to get this working. Thanks in anticipation of your help.
