GST applicability in case of petrol pump transaction

I am running a petrol pump. IOCL gives me dealer margin every month which is credited to my account.
IOCL also gives me tanker transportation reimbursement as I have my own tanker which is used to bring fuel from IOCL plant to my outlet.
Pls tell me whether GST applicable on above transactions or not.
If yes, then who is liable to pay GST?
