belgie-stripe 0.1.0

Stripe billing plugin for Belgie

Belgie Stripe: Billing and Subscription Management

Belgie Stripe adds Stripe customer creation, Checkout-based subscription acquisition, Customer Portal management, and webhook-driven subscription syncing to Belgie.

The package follows Belgie's plugin model:

• register Stripe(...) with auth.add_plugin(...)
• mount package-owned routes under /auth
• optionally inject StripeClient into your own routes
• compose explicit SQLAlchemy mixins instead of dynamic schema mapping

Installation

uv add belgie-stripe belgie-organization

For the umbrella package:

uv add belgie[alchemy,stripe,organization]

What It Provides

• Stripe settings for Stripe billing configuration
• StripePlugin for route mounting and dependency injection
• StripeClient for app-owned billing flows
• StripePlan and request/response models
• StripeAdapter and SQLAlchemy mixins for subscription persistence

Configuration

import stripe

from belgie_stripe import Stripe, StripePlan, StripeSubscription

stripe_client = stripe.StripeClient(
    "sk_test_...",
    http_client=stripe.HTTPXClient(),
)

plugin = Stripe(
    stripe=stripe_client,
    stripe_webhook_secret="whsec_...",
    subscription=StripeSubscription(
        adapter=subscription_adapter,
        plans=[StripePlan(name="pro", price_id="price_pro", annual_price_id="price_pro_year")],
    ),
)

Route Surface

Mounted under /auth:

• POST /stripe/webhook
• POST /subscription/upgrade
• GET /subscription/list
• POST /subscription/cancel
• POST /subscription/restore
• POST /subscription/billing-portal
• GET /subscription/success

Data Model

To use belgie-stripe with belgie-alchemy, compose these mixins into your models:

• StripeUserMixin
• StripeOrganizationMixin
• StripeSubscriptionMixin

Unlike Better Auth, Belgie does not do schema remapping at runtime. The Stripe columns and table are explicit model definitions that live in your application code.

Notes

• Organization subscriptions require the Belgie organization plugin and an explicit reference_id.
• Customer creation supports both lazy creation on first billing action and automatic creation during client.sign_up() when create_customer_on_sign_up=True.
• Injected StripeClient instances expose the raw async Stripe SDK as client.stripe for app-owned SDK calls.
• The package is designed around Stripe Billing APIs, Checkout Sessions, and Customer Portal.
