This is a "re-do" of the official spree_paypal_express extension. The old extension is extremely hard to maintain and complex.
Behind-the-scenes, this extension uses PayPal's Merchant Ruby SDK.
-
Add this extension to your Gemfile with this line:
gem 'spree_paypal_express', :github => "radar/better_spree_paypal_express", :branch => "2-0-stable" -
Install the gem using Bundler:
bundle install -
Copy & run migrations
bundle exec rails g spree_paypal_express:install
Go to PayPal's Developer Website, sign in with your PayPal account, click "Applications" then "Sandbox Accounts" and create a new "Business" account. Once the account is created, click on the triangle next to its email address, then "Profile". The "API Credentials" tab will provide your API credentials (probably). If this tab is blank, try refreshing the page.
You will also need a "Personal" account to test the transactions on your site. Create this in the same way, finding the account information under "Profile" as well. You may need to set a password in order to be able to log in to PayPal's sandbox for this user.
In Spree, go to the admin backend, click "Configuration" and then "Payment Methods" and create a new payment method. Select "Spree::Gateway::PayPalExpress" as the provider, and click "Create". Enter the email address, password and signature from the "API Credentials" tab for the Business account on PayPal.
Sign in to PayPal, then click "Profile" and then (under "Account Information" on the left), click "API Access". On this page, select "Option 2" and click "View API Signature". The username, password and signature will be displayed on this screen.
If you are unable to find it, then follow PayPal's own documentation.
Same as sandbox setup, but change "Server" from "sandbox" to "live".
The PayPal Express Checkout has no less than 4.5 billion configuration options.
This Spree extension supports some of those. If your favourite is not here, then please submit an issue about it, or better still a patch to add it in.
Determines whether or not a user needs a PayPal account to check out.
payment_method.preferred_solution_type = "Mark"
# or
payment_method.preferred_solution_type = "Sole""Mark" if you do want users to have a paypal account, "Sole" otherwise.
Determines which page to show users once they're redirected to PayPal.
payment_method.preferred_solution_type = "Login"
# or
payment_method.preferred_solution_type = "Billing""Login" will show the users the login form for PayPal, and "Billing" will show them a form where they can enter their credit card data and possibly sign up for a PayPal account (depending on the Solution Type setting above).
Determines what logo, if any, to display at the top left of the PayPal express checkout:
payment_method.preferred_logourl = 'http://yoursite.com/images/checkout.jpg'Must be an absolute path to the image.
Caveat venditor
Paypal will refuse any order with a zero cost item. Any such item will be skipped and not displayed.
PayPal will also refuse any order where item total (before taxes and shipping costs) is zero. In this case the PayPal checkout page will simply display "Current order".
