Important Notes

Transaction Creation: Transactions are ONLY created for successful bookings. Failed bookings do not create transaction records in the system.

Date Format: Always use YYYY-MM-DD format for dates (e.g., "2026-02-03").

Number of Nights Calculation: The system automatically calculates nights based on check-in and check-out dates. Check-out date is exclusive.

Booking Number: The booking_number field is what guests should present at hotel check-in. Make sure to display this prominently in confirmation emails/screens.

Reference Number: The reference field is the unique transaction identifier. Use this for tracking, customer support, and transaction queries.

Availability Check: Always verify room availability immediately before calling this endpoint by checking is_available in the rooms response.

Occupancy Validation: Ensure number_of_guests does not exceed the room's max_occupancy.

Phone Number Format: Use international format with country code: +234XXXXXXXXXX

Common Errors

Error Code	Error Message	Cause	Solution
422	Room is no longer available	Room already booked or unavailable	Check availability before booking
422	Invalid dates	Check-out before check-in or past dates	Ensure checkout_date > checkin_date and dates are in future
422	Exceeds occupancy	Too many guests for room type	Select larger room or book multiple rooms
400	Invalid phone format	Wrong phone number format	Use +234XXXXXXXXXX format
400	Invalid email	Malformed email address	Verify email format is correct
401	Unauthorized	Invalid or missing API key	Check X-API-KEY header

// 4. Verify room is available
if (!selectedRoom.is_available) {
  alert('Sorry, this room is no longer available');

Verifying Booking Status

After successful booking, you can verify the transaction using the reference number:

const reference = bookingResult.data.reference;
const verificationResponse = await fetch(`{{url}}/v2/merpi/transactions/${reference}`, {
  headers: {
    'X-API-KEY': 'your_api_key_here',
    'TransactionMedium': 'Web'
  }
});

const transactionData = await verificationResponse.json();
console.log('Transaction Status:', transactionData);

See Transaction Query documentation for complete details on verifying transactions.
