App Store Server API Golang Client
The App Store Server API is a REST API that you call from your server to request and provide information about your customers' in-app purchases.
The App Store Server API is independent of the app’s installation status on the customers’ devices. The App Store server returns information based on a customer’s in-app purchase history regardless of whether the customer installs, removes, or reinstalls the app on their devices.
go get github.com/jmolboy/appstoreLog in to App Store Connect and complete the following steps:
- Select Users and Access, and then select the Keys tab.
- Select In-App Purchase under the Key Type.
- Click Generate API Key or the Add (+) button.
- Enter a name for the key. The name is for your reference only and isn’t part of the key itself. Click Generate.
- Click Download API Key next to the new API key. And store your private key in a secure place.
