Configuration

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: text/plain' \
     -d ':paypal_express:
  :signature: "your-paypal-signature"
  :login: "your-username-facilitator.something.com"
  :password: "your-password"' \
     http://127.0.0.1:8080/1.0/kb/tenants/uploadPluginConfig/killbill-paypal-express

To go to production, create a paypal_express.yml configuration file under /var/tmp/bundles/plugins/ruby/killbill-paypal-express/x.y.z/ containing the following:

:paypal_express:
  :test: false

Usage

One-off payments

Create a payment method for the account:

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     -d '{
       "pluginName": "killbill-paypal-express",
       "pluginInfo": {}
     }' \
     "http://127.0.0.1:8080/1.0/kb/accounts/<ACCOUNT_ID>/paymentMethods?isDefault=true"

Without a pending payment

Generate the redirect URL using buildFormDescriptor (this will invoke SetExpressCheckout):

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     -d '{
       "formFields": [{
         "key": "amount",
         "value": 10
       },{
         "key": "currency",
         "value": "USD"
       }]
     }' \
     "http://127.0.0.1:8080/1.0/kb/paymentGateways/hosted/form/<ACCOUNT_ID>"

The customer should be redirected to the url specified in the formUrl entry of the response, e.g. https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-20G53990M6953444J.

Once the customer comes back from the PayPal flow, trigger the payment:

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     -d '{
       "transactionType": "PURCHASE",
       "amount": "10",
       "currency": "USD"
     }' \
     "http://127.0.0.1:8080/1.0/kb/accounts/<ACCOUNT_ID>/payments"

With a pending payment

Generate the redirect URL using buildFormDescriptor (this will invoke SetExpressCheckout):

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     -d '{
       "formFields": [{
         "key": "amount",
         "value": 10
       },{
         "key": "currency",
         "value": "USD"
       }]
     }' \
     "http://127.0.0.1:8080/1.0/kb/paymentGateways/hosted/form/<ACCOUNT_ID>?pluginProperty=create_pending_payment=true"

The customer should be redirected to the url specified in the formUrl entry of the response, e.g. https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-20G53990M6953444J.

Once the customer comes back from the PayPal flow, complete the payment (the payment id and external key are returned as part of the buildFormDescriptor call):

curl -v \
     -X PUT \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     "http://127.0.0.1:8080/1.0/kb/payments/<PAYMENT_ID>"

Recurring payments via a billing agreement ID (BAID)

Issue the following call to generate a Paypal token:

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     -d '{
       "kb_account_id": "13d26090-b8d7-11e2-9e96-0800200c9a66",
       "currency": "USD",
       "options": {
         "return_url": "http://www.google.com/?q=SUCCESS",
         "cancel_return_url": "http://www.google.com/?q=FAILURE",
         "billing_agreement": {
           "description": "Your subscription"
         }
       }
     }' \
     http://127.0.0.1:8080/plugins/killbill-paypal-express/1.0/setup-checkout

Kill Bill will return a 302 Found on success. The customer should be redirected to the url specified in the Location header, e.g. https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-20G53990M6953444J.

Once the customer comes back from the PayPal flow, save the BAID in Kill Bill:

curl -v \
     -X POST \
     -u admin:password \
     -H 'X-Killbill-ApiKey: bob' \
     -H 'X-Killbill-ApiSecret: lazar' \
     -H 'X-Killbill-CreatedBy: admin' \
     -H 'Content-Type: application/json' \
     -d '{
       "pluginName": "killbill-paypal-express",
       "pluginInfo": {
         "properties": [{
           "key": "token",
           "value": "20G53990M6953444J"
         }]
       }
     }' \
     "http://127.0.0.1:8080/1.0/kb/accounts/13d26090-b8d7-11e2-9e96-0800200c9a66/paymentMethods?isDefault=true"
