@ -17,4 +17,117 @@ This extension allows the store to use PayPal Express from two locations:
This extension follows the documented flow for a PayPal Express Checkout, where a user is forwarded to PayPal to allow them to login and review
the order (possibly select / change shipping address and method), then the user is redirected back to Spree to confirm the order. The user
MUST confirm the order on the Spree site before the payment is authorized / captured from PayPal (and the order is transitioned to the New state).
MUST confirm the order on the Spree site before the payment is authorized / captured from PayPal (and the order is transitioned to the New state).
USAGE (Checkout Payment)
========================
1. Setup your application
cp config/database.yml.example config/database.yml
rake db:bootstrap
Go ahead and load sample data
Fire it up to see that it works
Shut it down
2. Configure PPE
You'll need to have a Paypal developer account (developer.paypal.com) and both buyer and seller test accounts.
Tip: these are sandbox only, so use email addresses and passwords that are easy to remember, e.g. buyer@example.com and seller@example.com.
Your sandbox credentials are available from the API Credentials link.
Start your app
http://localhost:3000/admin/payment_methods/new
Name: Paypal Express
Environment: Development
Active: Yes
Provider: BillingIntegration::PaypalExpress
Create
Now add your credentials in the screen that follows
review: unchecked [1]
Signature: signature from your paypal seller test account
Server: test
Test Mode: checked
Password: API Password from your paypal seller test account
Login: API Username from your paypal seller test account
Update
3. Test it
Add an item to cart
Check out
Address step: complete it using a valid US address. (Use Sean Schofield's from the railsdog site ;))
Delivery step: pick anything
Payment step: pick Paypal Express. If this does not show up as an option, repeat Step 3.
The Check out with PayPal button should appear.
Make sure you're logged into your paypal developer account in another browser window before clicking it, as you'll be redirected to your test account (same browser, new window or tab).
On Paypal's site (your previously configured Seller test account), log in as the Buyer.
If you set up a test buyer account as buyer@example.com previously, use this now.
You should now see the paypal order details screen with a Pay Now button.
Click Pay Now
You should now see the spree apps thank you for your order page
4. Check the payment
http://localhost:3000/admin/orders
Edit your new order
Go to the Payments section from the right hand menu
Pending Payments should show Paypal Express with the options of Show and Capture
Click Show and look over the info available
The payment has status Pending with a successful authorization
Back to Payments
This time click Capture, then OK
Click Show to see what's changed.
You should now see two transactions, the previous Authorize transaction and a new Capture one with status Completed
NOTES
=====
To automatically capture funds, add this to you site extension's activate method:
if Spree::Config.instance
Spree::Config.set(:auto_capture => true)
end
[1] If you check the review checkbox in the admin section for Payment Methods/Paypal Express, the flow is slightly different. Instead of Pay Now on Paypal's order details page, it now says Continue. And the user is directed back to the spree app's Confirmation page showing a place order button. Use whichever suits your needs best. Personally, I leave review unchecked to cut down on the steps in the checkout flow.
