Server-to-server notifications are available on each Applications Store, to get real-time notifications of purchases, renewing…
They consist in messages, sent by the Applications Stores, every time an event occurs on a subscription. For instance, a message is sent when a subscription :
is cancelled (auto-renewing cancelled by user for the following billing period)
encounters a billing issue
The server-to-server notifications are not mandatory for making subscriptions work, but they are very valuable in the sense that they bring a real-time and comprehensive vision for the app editor.
The difficult part in integrating server-to-server notifications is the following :
it is quite (in fact very !) complex. There are lots of different messages, edge cases that need to be implemented
it has a totally different behaviour between the App Store and the Play Store, which brings even more complexity
When developing their IAP solution in-house, most app makers do not implement these server-to-server notifications, which prevent them from :
Having a real time vision of their subscribers base
Leverage on this to mitigate churn and optimise revenues
Avoid user fraud consisting in getting a yearly subscription and getting refund quickly for it
Purchasely Cloud Platform works as a middleware between the Mobile Applications Stores and your own platform :
It is connected to the stores and is the recipient of the S2S notifications
It translates these store specific notifications into a common simple language
It forwards every notification received directly on the Webhook to your own backend
The benefits for you is that, instead of having several notifications systems to implement, you can focus on one single and simpler interface. More over, as more stores are integrated into Purchasely product, there notifications are translated into the same common language, which means that you have nothing to do on your side !
In order to activate server-to-server on Purchasely, you need to connect each of your stores to the Purchasely Cloud Platform.
Here are the guides to connect each store :
