# settings.py

# PayFast Configuration
PAYFAST_MERCHANT_ID = '10023192'           # Your merchant ID

Usage Examples

Steps Taken When Using API Calls (To make it dynamic)

Create a payment (post) endpoint at: /payfast/payments/

// some fields are not required
// This is a post request
{
    "m_payment_id": "",
    "user": null,
    "amount": null,
    "item_name": "",
    "item_description": "",
    "name_first": "",
    "name_last": "",
    "email_address": "",
    "cell_number": "",
    "custom_str1": "",
    "custom_str2": "",
    "custom_str3": "",
    "custom_str4": "",
    "custom_str5": "",
    "custom_int1": null,
    "custom_int2": null,
    "custom_int3": null,
    "custom_int4": null,
    "custom_int5": null
}

This request returns something like this

{
    "amount": "99.99",
    "item_name": "Premium Subscription",
    "item_description": "1 month premium access",
    "name_first": "",
    "name_last": "",
    "email_address": "[e-mail]",
    "m_payment_id": "3a280ceb-344c-48d1-8e9c-7945f3f1194a",
    "payfast_url": "http://127.0.0.1:2000/payments/checkout/2"
}

if you are using a frontend app like REACTJS just redirect to 'payfast_url'

After the completion of this payment payfast will redirect to complete endpoint or cancelled endpoint

Steps Taken Using Query Parameters (To make it dynamic)

Example 1: E-commerce Checkout

# views.py
from django.shortcuts import redirect, reverse
from urllib.parse import urlencode
from .models import Order

def process_order_checkout(request, order_id):
    """
    Process order and redirect to PayFast checkout
    """
    order = Order.objects.get(id=order_id, user=request.user)
    
    # Calculate total
    total = order.calculate_total()
    
    # Build item description
    items = ', '.join([f"{item.quantity}x {item.product.name}" 
                       for item in order.items.all()])
    
    params = urlencode({
        'amount': total,
        'item_name': f'Order #{order.id}',
        'item_description': items,
        'custom_str1': f'order_{order.id}',
        'custom_int1': order.items.count(),
        'email_address': request.user.email,
    })
    
    url = f"{reverse('payfast:checkout')}?{params}"
    return redirect(url)
