• Look into google account set-up process

I don't believe any new accounts will be needed. There is already a merchant account operated by FR-tech that we will use.

• Explore and document implementation steps for native GPay

The steps are as follows:

• Design and build the user interface for initiating and completing the transaction, while using a sandbox "test" environment provided by Google Pay, without yet needing to communicate with our backend API.
  • If necessary, we can try making sample payment requests to a backend staging environment that FR-tech can set up. This testing can be in parallel with development of the user interface.
• Take screenshots of each step of the completed workflow and submit them for approval.
• Once approved, we can switch from the "test" environment to the production GPay environment.
• The end result of a GPay transaction is a token that we will forward to FR-tech's existing payments backend, which will complete the transaction.
  • At this stage we will do final testing to see how our backend handles this token, and see if any tweaks need to be made.
