how do i store some value to use after redirected from Payment gateway

i want to store some value to use later when the page is being redirected back from payment gateway. 
for ex. i want customer name, address later after the payment is successful.
i have tried using session for that but the session value got destroyed after redicted from another domain or server.
i am new to this so please explain properly. 
i am using Codeigniter 4.
