Any example of sending apprequest app-to-user?

Question

How can I send apprequest (app for user)? Do I need special permission for this or just a user id? Any limit on the number of users per request? Has anyone received a sample code for sale?

I have already checked these links: https://developers.facebook.com/docs/requests/ https://developers.facebook.com/docs/reference/dialogs/requests/ https://developers.facebook.com/docs/reference/api/user/#apprequests 

Answer 1

I don’t think that requests from the application to the user are going to get what you want. Because they can only be sent to current application users.

From: https://developers.facebook.com/docs/requests/

Application to user requests

Applications for user requests can be used to reconnect the user in the application and can only be sent to users who have installed the application. For example, notifying the user that something has changed since their last visit, "10 of your friends are now online."

The application for the user request is sent via the Graph API, for more information see the docs apprequests. Applications for user requests are available only for the Canvas Application, and not websites, since receiving the request will direct the user to the URL of the canvas page of the application that sent the request. Notification Users request application

Applications for user requests do not generate notifications, although they do appear in the application and games panels and increase the application’s bookmark counter similar to User to User Requests. Application Acceptance

This process is identical to accepting a user's user request.

From https://developers.facebook.com/docs/reference/api/user/#apprequests

Create

You can publish a request for a user by sending an HTTP POST request to / USER _ID / apprequests with the access_token application.

Note. POST for the API endpoint API / USER_ID / apprequests is considered an expression per application for the user. Requests created by applications do not receive notifications and receive limited distribution compared to user requests sent to users using the query dialog box
