To enable Google Play Android Developer API:

Navigate to the Google Play Android Developer API page in the Google Cloud Console. (If you have multiple Google Cloud projects, ensure the correct one is selected.)
Click Enable.

You can create a service account from the Google Cloud Console by following the steps below:

Go to the Google Cloud Console
If prompted, select a Project

Navigate to Service Accounts.
- In the left sidebar (click the hamburger menu icon ☰ if it’s hidden), go to IAM & Admin > Service Accounts.
At the top of the Service Accounts page, click on + Create Service Account.
Under Service Account Name, enter ZYPE-SERVICE-API and under Service Account Description, enter Receipt Validation.
Note down your Service account ID and click on Create and continue.

Choose 'Select a Role' from the dropdown.
