Google is worried about the financial security of developers. The company has launched the Purchase Status API system, which allows you to track the purchase status using standard GET requests.

The system works simply: you specify the name of the application package (app package name), purchase or subscription ID, and receive a JSON object containing general information about the order and its status.

The scope of the innovation is extensive. So the Purchase Status API can be used to process individual orders, to verify the purchase or expiration of the order. You can also get information about cancelled orders.

Unfortunately, an individual developer at the moment can send no more than 15 thousand requests per day, however, you can send a request to Google to increase the limit.
