How I can be notified when a Facebook page - I don't own- published a new post ?
I am creating a news app and want to add Facebook pages of news websites. I dont want to pull new posts every 30 minutes for example. I want to be notified when there is a new post.
I read real time updates https://developers.facebook.com/docs/graph-api/real-time-updates/v2.3
but it says that I must be the owner of the page or I can link my app to that page which I can't do.
Is there any alternative solution ?
There is only one alternative solution: You can use an App or User Token to check for new posts manually with a cron job - by using the Page Feed endpoint.
