How to correctly enter the URL of the ios application when submitting an ad for installing an application on facebook?

Question

Facebook

Guys who ran ads for the app on facebook? When you fill in all the columns and click to place an order, it gives an error on the screen. Says something like the wrong url of the link to the application. I don’t understand, it’s like I’m indicating the url of the application page in the store that Apple sent in a letter when accepting the app for sale. Tell me what's wrong? And then you can't reach support.
