Rest API - Laravel to Laravel

Hello, I have a laravel application and I have a question regarding connecting another laravel application with api.

I have a student table and in this table has the data 'ID' and 'CPF'. I would like to know what the best way for the student to connect by id and cpf of him.

I made the api connection and saved the data I received in a session and displayed on the screen, but when I leave the page and return to the data it disappears and appears every time it gives a reload on the page.
