I am using the above reference to assign a group ID to my tickets and it says the datatype is integer however the group IDs are larger than what Int32 supports. If I change it to be a Int64 (long) datatype then I get response 422 on my response.

Can you send through an example of the payload you're sending to the API along with a screenshot of the error you're seeing?
Thanks!
