Stripe payment components for Reflex applications

A Reflex custom component library wrapping @stripe/react-stripe-js for seamless Stripe payment integration in Python.

Features

• Express Checkout — Apple Pay, Google Pay, and Link via ExpressCheckoutElement
• Embedded Checkout — Full Stripe-hosted checkout form in an iframe
• Backend State Management — StripeState handles PaymentIntents and Checkout Sessions
• API Routes — Auto-registered FastAPI endpoints for client-server communication
• Type-Safe Config — Pydantic-style Appearance, ExpressCheckoutOptions, and more

Installation

pip install reflex-stripe

uv add reflex-stripe

Quick Start

Express Checkout

Drop in a complete Express Checkout (Apple Pay / Google Pay) with a single provider:

import os
import reflex as rx
import reflex_stripe as stripe

def checkout_page() -> rx.Component:
    return stripe.stripe_provider(
        stripe.ExpressCheckoutBridge.create(
            return_url="/checkout/complete",
        ),
        publishable_key=os.environ["STRIPE_PUBLISHABLE_KEY"],
        secret_key=os.environ["STRIPE_SECRET_KEY"],
        mode="payment",
        amount=1099,
        currency="usd",
    )

Embedded Checkout

Render a full Stripe Checkout form as an embedded iframe:

import os
import reflex as rx
import reflex_stripe as stripe

def checkout_page() -> rx.Component:
    return stripe.embedded_checkout_session(
        publishable_key=os.environ["STRIPE_PUBLISHABLE_KEY"],
        secret_key=os.environ["STRIPE_SECRET_KEY"],
        line_items=[{
            "price_data": {
                "currency": "usd",
                "product_data": {"name": "Pro Plan"},
                "unit_amount": 2000,
            },
            "quantity": 1,
        }],
        return_url="/checkout/complete",
    )

Register API Routes

Register the Stripe backend endpoints on your Reflex app:

app = rx.App()
stripe.register_stripe_api(app)
