Inline buttons have a callback_data field that can contain arbitrary data.
When sending the button to the user (response from the bot), depending on the application logic, you put the necessary string there, which will then be returned to the server when the user clicks the button.
For example, it can be callback_data = "list_sushi_page_2" which will mean for you "the user clicked the transition to the 2nd page of the list" or alternatively "/list_sushi? from=11&to=22" and so on.
