​
Overview

The BIN Lookup endpoint allows you to retrieve card information by providing the first 8 digits of a card number (BIN). This is useful for identifying card details before processing a payment, enabling you to:
  • Determine card network (visa, mastercard, rupay, amex, etc.)
  • Identify card type (credit or debit)
  • Get bank information
  • Check if the card is domestic or international
This endpoint helps you provide better user experience by pre-validating card information and displaying appropriate payment options.

​
Use Cases

  • Pre-validation: Validate card details before submitting payment
  • UI Enhancement: Show card network logo or bank name as user types
  • Payment Flow Optimization: Determine payment method eligibility based on card type
  • Fraud Prevention: Identify potentially suspicious cards before processing
