In App Purchase Receipt Validator

The receipt validator handles a lot of important things: it makes sure no one can fake a purchase and gain access to your app, it also handles requests that handle activation and cancellation of memberships.

  • Make sure you have version 2.0.0 of the AppPresser in app purchase plugin installed and activated on your WordPress site.
  • You must setup your in app purchases in the app stores before you can setup the validator

How it Works

When someone purchases in your app, here's what happens:

  1. New users are registered on your WordPress site, and logged into the app.
  2. The purchase information is sent to the app store, and we get back a receipt. 
  3. The receipt is then sent to the receipt validator, and the app gets back a response. If the purchase is valid, the app completes the purchase.
  4. The receipt validator sends a webhook to your WordPress site to add the user to your membership level, course, or whatever you have setup.


When someone cancels their subscription:

  1. The app stores send a notification to the receipt validator. 
  2. The validator sends a webhook to your WordPress site to cancel the user from your membership level or course.

Keep in mind that subscriptions need to be managed through the app stores. If you change an expiration date or price in your WordPress membership plugin, it does not change in the app stores.
