Configure your app's backend

This section describes the steps to integrate your app's backend with Cloud Marketplace. With this integration, you can manage users' accounts and entitlements , which indicate that users have bought your product from Cloud Marketplace. If you chose a usage-based pricing model, you also integrate your backend to report usage to Google.

For an example of integrating a basic app with Cloud Marketplace and a walkthrough of the sample code, see the codelab to integrate a managed service .

For the sample code used in the codelab, see the GitHub repository .

Before you begin

• Set up access to the Cloud Commerce Partner Procurement API, as described in Integrate your app .
• If you chose a usage-based pricing scheme, verify that your Partner Engineer has created a service that you can report usage against. This service displays in the Service domain field of the Billing Integration section of Producer Portal.
