PayPal Anypoint Connector helps integrate and PayPal within MULE. I have developed the sample program that connects to a PayPal account to do the -getbalance operation.

Used in this tutorial:

• MULE ESB 3.8

• Anypoint Studio 6.0

• PayPal Connector (Mule 3.7.0 +)

Step 1: Install the paypal connector in the anypoint studio and restart the studio to reflect the chagnes.

Step 2: Use the HTTP listener to post the request to the PayPal API.

<http:listener config-ref="HTTP_Listener_Configuration" path="/getbalance" doc:name="HTTP"/>

Here's the listener config ref:

<http:listener-config name="HTTP_Listener_Configuration" host="localhost" port="8081" doc:name="HTTP Listener Configuration"/>

Step 3: Drag and drop the PayPal connector and configure the PayPal connection details.

Created a sandbox account in PayPal and gather the API details (username, password, signature, appID, etc.)

You'll need the following details to configure PayPal:

• Username.

• Password.

• ServiceAddress.

• Signature.

• AppId.

Here's the PayPal config:

<paypal:config name="PayPal" username="" password="" serviceAddress="" signature="" appId="" doc:name="PayPal Connector: configuration (Signature)"/>

And the PayPal connector entry:

<paypal:get-balance config-ref="PayPal" doc:name="PayPal"/>

Flow pic and XML:

<http:listener-config name="HTTP_Listener_Configuration" host="localhost" port="8081" doc:name="HTTP Listener Configuration"/>  
<paypal:config name="PayPal" username="" password="" serviceAddress="" signature="" appId="" doc:name="PayPal Connector: configuration (Signature)"/>    
<flow name="httpexampleFlow1">      
<http:listener config-ref="HTTP_Listener_Configuration" path="/getbalance" doc:name="HTTP"/>   
    <paypal:get-balance config-ref="PayPal" doc:name="PayPal"/>   
</flow>

Run the Mule project in Anypoint Studio and access the URL for getbalance.
