<b>FastSpring plugin installation</b>

 1. Configure plugin at aMember CP -> Setup/Configuration -> FastSpring

 2. Configure FastSpring Product ID/Name at aMember CP -> Manage Products -> ->Billing Plans
 
 4. Configure Remote Server URL in your FastSpring account (NOTIFY -> Add Notification Rule)

    Format: HTTP Remote Server Call
    Type:  Order Notification
    Remote Server URL: %root_surl%/payment/fastspring/ipn

    Optionally, after clicking 'Next' button you can add following 'HTTP Parameters'.
    
    Name: SubscriptionURL
    Value: #{order.allItems[0].subscription.url.detail}

    Name:  OrderReference2
    Value: #{order.allItems[0].subscription.reference}
    
    Name:  OrderReferrer2
    Value: #{order.allItems[0].subscription.referrer}

 5. Run a test transaction to ensure everything is working correctly.

 Note: You can setup in FastSpring the same coupon code as in aMember.
