Beta
Thread-safe Webhook App Engine Servlet to receive notifications.
In order to use this servlet you need to register the servlet in your web.xml. You may optionally extend AppEngineNotificationServlet with custom behavior.
It is a simple wrapper around WebhookUtils#processWebhookNotification(HttpServletRequest, HttpServletResponse, DataStoreFactory) that uses AppEngineDataStoreFactory#getDefaultInstance(), so you may alternatively call that method instead from your HttpServlet#doPost with no loss of functionality. Sample web.xml setup:
{@literal <}servlet{@literal>}
{@literal <}servlet-name{@literal>}AppEngineNotificationServlet{@literal <} ervlet-name{@literal="">}
{@literal <}servlet-class{@literal>}com.google.api.client.googleapis.extensions.appengine.notifications.AppEngineNotificationServlet{@literal <} ervlet-class{@literal="">}
{@literal <} ervlet{@literal="">}
{@literal <}servlet-mapping{@literal>}
{@literal <}servlet-name{@literal>}AppEngineNotificationServlet{@literal <} ervlet-name{@literal="">}
{@literal <}url-pattern{@literal>}/notifications{@literal <} rl-pattern{@literal="">}
{@literal <} ervlet-mapping{@literal="">}
