dj-paddle

Django + Paddle Made Easy

(this project is heavily inspired by dj-stripe)

Introduction

dj-paddle implements Paddle models (currently Subscription only), for Django. Set up your webhook and start receiving model updates. You will then have a copy of all Paddle subscriptions available in Django, no API traffic required!

The full documentation is available at https://dj-paddle.readthedocs.io.

Features

• Django Signals for all incoming webhook events from paddle
• Subscriptions

Requirements

• Django >= 2.1
• Python >= 3.5

Quickstart

Install dj-paddle:

pip install dj-paddle

Add djpaddle to your INSTALLED_APPS:

INSTALLED_APPS =(
    ...
    "djpaddle",
    ...
)

Add to urls.py:

path("paddle/", include("djpaddle.urls", namespace="djpaddle")),

Tell paddle about the webhook (paddle webhook docs can be found here) using the full URL of your endpoint from the urls.py step above (e.g. https://example.com/paddle/webhook/).

Add your paddle keys and set the operating mode:

# can be found at https://vendors.paddle.com/authentication
DJPADDLE_VENDOR_ID = '<your-vendor-id>'

# create one at https://vendors.paddle.com/authentication
DJPADDLE_API_KEY = '<your-api-key>'

# can be found at https://vendors.paddle.com/public-key
DJPADDLE_PUBLIC_KEY = '<your-public-key>'

# More info at https://developer.paddle.com/getting-started/sandbox
DJPADDLE_SANDBOX = False

djpaddle includes vendor_id and sandbox template context processors which adds your vendor ID as DJPADDLE_VENDOR_ID and if you want to use the sandbox as DJPADDLE_SANDBOX to each template context:

TEMPLATES = [
{
    ...
    'OPTIONS': {
        ...
        'context_processors': [
            ...
            'djpaddle.context_processors.vendor_id',
            'djpaddle.context_processors.sandbox',
            ...
        ]
    }
}

Run the commands:

python manage.py migrate

# fetches all subscription plans from paddle
python manage.py djpaddle_sync_plans_from_paddle

Paddle Checkout

Next to setup a PaddleJS checkout page

First load in PaddleJS and initialise it by including the dj-paddle PaddleJS template in your own template to load PaddleJS:

{% include "djpaddle_paddlejs.html" %}

Next add a Paddle product or subscription plan into the page context. Below is an example of how to do this using a class based view where plan_id is passed through as a value from the URL:

from django.conf import settings
from django.views.generic import TemplateView
from djpaddle.models import Plan


class Checkout(TemplateView):
    template_name = 'checkout.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['paddle_plan'] = Plan.objects.get(pk=kwargs['plan_id'])
        # If you have not added 'djpaddle.context_processors.vendor_id' as a template context processors
        context['DJPADDLE_VENDOR_ID'] = settings.DJPADDLE_VENDOR_ID
        # If you have not added 'djpaddle.context_processors.sandbox' as a template context processors
        context['DJPADDLE_SANDBOX'] = settings.DJPADDLE_SANDBOX
        return context

Finally put a Buy Now! button for the plan subscription you added to the context:

<a href="#!" class="paddle_button" data-product="{{ paddle_plan.id }}">Buy Now!</a>

You can pass data to Paddle JS by add data attributes to the button. For example to set the users email you can use the data-email attribute:

<a href="#!" class="paddle_button" data-product="{{ paddle_plan.id }}" data-email="{{ user.email }}" >Buy Now!</a>

A full list of parameters can be found on the PaddleJS parameters page

For more information about options on what to do after a successful checkout please see our Checkout success documentation

Subscription model

You can override the model that subscriptions are attached to using the DJPADDLE_SUBSCRIBER_MODEL setting. This setting must use the string model reference in the style 'app_label.ModelName'.

The model chosen must have an email field.

# Defaults to AUTH_USER_MODEL
DJPADDLE_SUBSCRIBER_MODEL = 'myapp.MyModel'

Warning: To use this setting you must have already created and ran the initial migration for the app/model before adding djpadding to INSTALLED_APPS.
