No access to the data of my Kiwigrid after update

I ve actually found an better solution:
If you get the data of the “kiwisessionid” Cookie manually once you can just give it as a parameter with your request that will look something like this:

headers:
Cookie: kiwisessionid=“Cookie Value”

To my knowlage the cookie only become invalid after not beong used for a certain time or if its active for 400 days (which is standard)
