Subscriptions allow merchants to charge buyers on a regular, recurring basis without additional buyer input.

Google Checkout offers two types of subscriptions:

• Google-Handled Subscriptions

  • Simple, but powerful.
  • After the subscription is submitted, the merchant does not have to take any further action.

• Merchant-Handled Subscriptions

  • Provide maximum flexibility.
  • After the subscription is submitted, the merchant submits the recurrence requests at every recurrence period.

For information on how to implement Subscriptions, please refer to the following documentation.

Advanced Buyer Messaging allows buyers to add gift messages, add instructions, or request gift receipts for Google Checkout orders.

• Gift messaging allows the buyer to write a personal note to the order recipient. Google Checkout offers four types of gift messages, and the only difference between those types is the text that the Google Checkout UI displays:

  • gift message
  • in honor of message
  • in memory of message
  • in tribute of message

• Gift receipts demonstrate proof of a transaction for the purpose of returning or exchanging items in an order. However, gift receipts omit certain information that is typically printed on a standard receipt, including the price paid for each item in the order and the order total.

• Instructions allow the buyer to provide special instructions or information that is intended for either the merchant or the shipping carrier. Google Checkout offers four types of instructional messages, and the only difference between those types is the text that the Google Checkout UI displays:
  • buyer note
  • delivery instructions
  • special instructions
  • special requests

The Polling API introduces a data-pull model for retrieving Google Checkout notifications. With the Polling API, you can actively request notifications instead of setting up a server that constantly listens for notification callbacks.

The Polling API is designed to simplify your efforts to integrate the Notification API because you don't need to:

• Obtain an SSL certificate to implement the Polling API.

• Open your firewall to support or test notifications in a development environment.

• Operate a web service that is always available to receive and process notifications.

For information on how to implement the Polling API, please refer to the following documentation.
