​

Basic Scenario

A customer logs in to your self-care portal and chooses to purchase a single use product. For example, an existing subscriber with a video streaming subscription wants to purchase a movie. Single use products allow customers to purchase a service that does not recur.

​

Design Approach

The existing customer logs into your self-care application and selects the single use product for purchase. The self-care application uses the attributes of the single use product in conjunction with the end user account and payment information to call the transactions endpoint to create a one-time transaction for this purchase. If entitlements are in scope, upon successful completion of the one-time transaction, grant the appropriate entitlements (from the single-use product attributes) to the customer using the accounts endpoint.

Create the Single Use Transaction for Existing Customers Using Subscribe APIs

• Create the single use product in Subscribe using either the portal or API (see Configure Single Use Products Using the Subscribe Portal).
• Refresh your product catalog cache using the products endpoint (see Set Up Local Data Cache of Products to Display on Your Online Storefront).

To create the one-time Transaction for existing customers:

1. Use the transactions endpoint to create the one-time transaction.
2. (optional) Use the accounts endpoint to create the entitlements grant for the single use content. Sample Code 2-4-15 Sample Code

• A one-time Transaction is generated if applicable, including any applicable taxation, and charged to the customer’s on-file payment information.
• The Account has been granted appropriate entitlements, if applicable.
