We use Slack message server, but it sends too many messages everyday. When we click the customer id to see his purchase history, we notice that he has subscribed before we add RevenueCat SDK in our app. So how can we stop getting these old customers’ messages, only get new purchases’ messgaes?

For iOS, Apple actually sends us the entire purchase history in the receipt. It sounds like your app migrated to RevenueCat and when a customer on the old version of the app migrates to the version of the app with RevenueCat, their receipt is synced with our servers we will parse through the receipt. We also notify integrations of the most recent transaction so systems can stay up to date.
