Hi
I am developing a payment app using php and
on oauth onboarding process I am stuck with the oAuth callback

Refer : link 

as what to pass as a cookie parameter to get access to the session object and get the shop data using sessions

Kindly help If anyone have any idea related to this

The documentation for how to pass the cookie parameter in the oauth is really bad. There’s no examples! I’ve been searching for a solution myself for two days. If you figure it out please let me know.
