spree-paypal_platform

PayPal Checkout for Spree 5.6+, as a single payment method covering the PayPal wallet, Apple Pay, and Card Fields.

Published gem: spree-paypal_platform
Require: spree/paypal_platform
Constant: Spree::PaypalPlatform

This is not the official spree_paypal_checkout gem. It started from that extension (VAT AMOUNT_MISMATCH guard, storefront-owned address) and adds Apple Pay as a funding source of the same gateway.

What it is

  • One Spree::PaypalPlatform::Gateway payment method.
  • Checkout goes through Spree's Store API v3 payment sessions (POST /api/v3/store/carts/:id/payment_sessions → complete).
  • The storefront owns the address. The gem pins it with SET_PROVIDED_ADDRESS so PayPal does not re-collect it.
  • Amount breakdown sends only additional_tax_total. Sending full tax_total double-counts included VAT and trips PayPal AMOUNT_MISMATCH.
  • Talks to PayPal via the official paypal-server-sdk gem (~> 2.3).

Apple Pay is not a second payment method and not a Spree Integration. It is a payment_source.apple_pay on the same Checkout order.

Installation

gem 'spree-paypal_platform'

bundle install
bin/rails g spree:paypal_platform:install

The generator copies the migrations. Pass --auto-run-migrations to skip the prompt.

Then add a PayPal payment method in admin and set:

Preference Purpose
client_id / client_secret REST app credentials from the PayPal Developer Dashboard
webhook_secret PayPal webhook ID (used as the verify-webhook webhook_id)
test_mode Sandbox vs live
enable_apple_pay Advertise Apple Pay to headless storefronts (default on)
apple_pay_domain Domain registered with PayPal for Apple Pay

Webhook URL is the standard Spree v3 payments webhook:

https://<store>/api/v3/webhooks/payments/<prefixed-payment-method-id>

Apple Pay

  1. Enable Apple Pay on the PayPal business account.
  2. Register every storefront domain (and subdomain) that will show the button in the PayPal Apple Pay domain registration dashboard.
  3. Headless storefronts load the PayPal JS SDK with components=applepay and render Apple's ApplePaySession. The gem records payment_source.apple_pay as Spree::PaypalPlatform::PaymentSources::ApplePay.
  4. Safari + HTTPS only.
