Two things- if it is within 3 days of your due date, you have grace period and will be waived off.
If it is for the first time, you can always request, they will reduce the quantum of penal interest, if not the full amount. Happened to me last year, it was a new card and did not realize due date. Got the call from Axis, paid the dues almost after a week but surprisingly they did not charge me anything and even my CIBIL was not affected.
