I guess you haven't even applied.
If you don't have any CC till now, plz check your CIBIL Score. Amazon ICICI at times is rejected for people not having any CIBIL score or if CIBIL history is less than 1 yr old.
Try anyways, wishing you best of luck.
However, if you're rejected due to CIBIL score, then try applying for ICICI Platinum (it's free, and easily available for people having accounts in ICICI)
Or, ask your bank RM for best card you can get LTF, based on your salary or bank balance.
