Launch process and certification

Once development nears completion, the integrator and Google can start the certification and launch process. The launch process consists of end to end testing across devices and form factors.

Testing will occur in three phases:

  • Integration testing
  • Finance testing
  • Dogfood

Some of the phases can overlap such as integration and finance testing.

Once testing is complete and both parties are satisfied with the integration, staged launch can occur.

Integration testing

The purpose of integration testing is to verify that all API requests/responses and user experiences are handled correctly. The list of tests that Google will perform can be found in the integration testing doc.

Google will run through the relevant tests from the testing spreadsheet. You should make a copy of the testing spreadsheet to track your testing progress. Initially these tests should be performed using the Imali Testing Tool. Once Google configures the integrator in production, the integrator should complete end to end tests using Google Play.

While not strictly defined in this document, the integrator should test across a variety of mobile devices from different manufacuturers and Android versions. The integrator must also test to ensure that their production environment meets the SLA agreed to in the contract.

The integrator and Google will set up weekly meetings during this period to debug issues and answer any questions. Additionally, Google will create a hangouts group for low response time chats. The integrator and Google should set up some overlap working time to ensure that questions and bugs are resolved in a timely manner.

Google will test the integration in two environments:

  • Google sandbox -> integrator sandbox
  • Google prod -> integrator prod

For each environment the integrator is expected to provide:

  • API end point URLs
  • Sample accounts preloaded with funds
  • APK for authorization if necessary

To test their endpoints the integrator can use the Imali integration testing tool. Once ready, Google will enable the production configuration so allowlisted users to see the payment method on Google properties.

Finance testing

Finance testing consists of verifying both that the integrator is able to successfully remit to Google and that Google is able to automatically match the payment.

As part of testing, Google asks the integrator to perform five different remittance scenarios:

  • Successful match with memoLineId
  • Overpay
  • Underpay
  • Overpay > 5%
  • Underpay > 5%

Google will send the integrator several remittanceStatementNotifications, and the integrator should pay according to one of these scenarios. Google will notify the integrator beforehand to initiate the finance testing flow.

Once both parties are ready, dogfood testing can begin. Finance testing can also occur during dogfood if timelines are compressed.


Dogfooding allows Google and the integrator to test real world end user experience. Google will enable the form of payment on Google properties such as Play for Googlers. This enables local testing across a mix of devices, connections and OS versions.

Dogfood testing must occur in both the integrator's and Google's production environment.

Dogfood typically occurs for two weeks before launch. During this period the integrator and Google can expect to have daily syncs on the status of outstanding issues.

By the end of dogfood all launch blocking issues should be resolved. Dogfood can be extended if additional testing or fixes need to occur.

Once all three phases have been successfully completed, testing and certification is complete.


Both the integrator and Google need to give approval for launch.

Launch will start with a 1% roll out. Rolling out to 100% typically takes one month with the following roll out stages each lasting about a week.

  • 1% - Test for device issues
  • 5% - Widen pool of users and devices
  • 10% - Test for revenue impact
  • 50% - Test for scalability
  • 100% - Full launch
