How to apply for HDFC Bank Regalia Gold Credit Card online and what documents are required?

The 'minimum due' trap is real. Banks love it because they charge ~36-42% interest on the carried-forward amount. If you can't pay the full bill this month, pay at least 50% — anything below that and the interest eats the rewards of the next 6 months.

Yes the rewards sound amazing in marketing, but the redemption catalogue is full of products at inflated MRP. The statement credit redemption is almost always the best value. Skip the merchandise, skip the flight bookings, take the cash.
