Facebook notification from my app appears and disappears

Question

I have a problem since a several days now. Facebook notifications from my app (the red number one) appears and disappears. This functioning properly at first, but then but then stopped working. I tried by entering in the Website url -> http://mipagina.com, in the canvas url -> http://mipagina.com/ and the secure url https.... I tried many other ways but nothing. I realized that the app request don't send a notification to the user for his acceptance. But I can add the app from the app page. If the user add the app the red number one appears and then disappears but the notification from my app shows in the facebook notifications page. But if the user doesn't add the app, the red number one appears and then disappears and then the notification doesn't appear in the facebook notifications page. Hope you can help me...Please sorry for my english.

Answer 1

Since "user-to-user requests are only available in canvas apps" (see here), you must make sure your canvas app is properly set up.

Review that you have done ALL of the following steps:

• Set Sandbox Mode to off
• Selected a Namespace for your app
• Enabled App on Facebook (which is the canvas app settings)
• Filled out Canvas URL and Secure Canvas URL

Facebook will not notify you in its Javascript API about these issues: there it will seem like the app request notification has indeed successfully been delivered.
