I would appreciate if you can let me know how can I get Instructor Email in LTI call
If you mean in the LTI launch data, then you cannot get it. The only email address available will be for the launching user.
If you are using LTI 1.3 and your tool has permission to use the names and roles provisioning service, then you could use that to get the email address, assuming the privacy level is public.
Otherwise, your tool would need API access and get it via an API call.
Thanks for your reply. Is there any way that instructor can pass custom parameter such as project name or id via LTI?
I've only come across adding custom parameters to a tool at the admin level, haven't seen them customisable at the course level. This is something you'd hope to be able to do. Would be nice if there was a setting or something to enable it.
