Creating Payment Transaction

To generate QR code data for a transaction, create an instance of the KHQR() class with Bakong Token and call the:

• create_qr() method with the required parameters.
• generate_deeplink() method with the required parameters.
• generate_md5() method with the required parameters.
• check_payment() method with the required parameters.
• get_payment() method with the required parameters.
• check_bulk_payments() method with the required parameters.

Example:

from bakong_khqr import KHQR

# Create an instance of KHQR with Bakong Developer Token:
khqr = KHQR("eyJhbGciOiJIUzI1NiIsI...nMhgG87BWeDg9Lu-_CKe1SMqC0")

# Generate QR code data for a transaction:
qr = khqr.create_qr(
    bank_account='user_name@bank', # Check your user_name@bank under Bakong profile (Mobile App)
    merchant_name='Your Name',
    merchant_city='Phnom Penh',
    amount=9800, #9800 Riel
    currency='KHR', # USD or KHR

# Generate Deeplink:
deeplink = khqr.generate_deeplink(
    qr,
    callback="https://your_website.com/shop/details?q=ABC", # Or your app's custom scheme (e.g., mshop://purchase/39482)

# Get Hash MD5
md5 = khqr.generate_md5(qr)
print(md5)
# String Result: dfcabf4598d1c405a75540a3d4ca099d

# Check Transaction paid or unpaid:
payment_status = khqr.check_payment(md5)
print(payment_status)
# String Result: "UNPAID"
# Indicates that this transaction has not yet been paid.

# Retrieve the payment information:
#e.g. In case static QR code (static=True) is used for payment, and the amount is not known from the user's input.
payment_info = khqr.get_payment(md5)
print(payment_info)

# You can retrieve information such as the amount to integrate into your system.

# Check Bulk Transactions:
md5_list = [
    "dfcabf4598d1c405a75540a3d4ca099d",

    "31bca02094ad576588e42b60db57bc98"
]

bulk_payments_status = khqr.check_bulk_payments(md5_list)
print(bulk_payments_status)
# List Result: ["5154e4f795634ff1a0ae4b48e53a6d9c", "495fdaec0be5d94c89bc1283c7283d3d"]
# Returns a list containing only the MD5 hashes that correspond to successful (paid) transactions.


# ⚠️ Bulk Transaction Check Limit
# The Bakong API allows a maximum of 50 MD5 hashes per request when using the check_bulk_payments() method.
#If you pass more than 50 hashes, the function will raise a ValueError to prevent unexpected API errors.

md5_list = [md5_1, md5_2, ..., md5_51]  # 51 hashes

# This will raise:
# ValueError: The md5_list exceeds the allowed limit of 50 hashes per request.
result = khqr.check_bulk_payments(md5_list)

# ✅ If you need to check more than 50 transactions, you must handle chunking manually:
def chunked(iterable, size=50):
    for i in range(0, len(iterable), size):
        yield iterable[i:i + size]

all_md5 = [...]  # more than 50 md5 hashes
paid_md5 = []

for batch in chunked(all_md5):
    paid_md5.extend(khqr.check_bulk_payments(batch))

print(paid_md5)
# List Result: ["5154e4f795634ff1a0ae4b48e53a6d9c", "495fdaec0be5d94c89bc1283c7283d3d"]
# Returns a list containing only the MD5 hashes that correspond to successful (paid) transactions.

Generate QR Image

The qr_image() method generates a QR code image from a QR string. Make sure you install the optional [image] extras to get dependencies like Pillow and qrcode:

pip3 install "bakong-khqr[image]"

Example:

from bakong_khqr import KHQR

khqr = KHQR("your_bakong_token")

qr = khqr.create_qr(
    bank_account='user_name@bank',
    merchant_name='Your Name',
    merchant_city='Phnom Penh',
    amount=100.00,
    currency='USD',
    store_label='MShop',
    phone_number='85512345678',
    bill_number='TRX123456',
    terminal_label='Cashier-01',
    static=False
)

# Generate QR image as PNG file path
png_path = khqr.qr_image(qr)
print("QR image saved at:", png_path)

Parameters for create_qr() Method

• bank_account: The bank account associated with the transaction.
• merchant_name: Name of the merchant.
• merchant_city: City where the merchant is located.

• phone_number: Contact phone number.
• bill_number: Reference number for the bill.
• terminal_label: Label for the terminal.
• static: Static or Dynamic QR code (default: static = False).

Note: Using static mode will create a Static QR Code for payment, allowing unlimited transactions, usage, and a zero amount included.

Parameters for generate_md5() Method

• qr: Valid QR Code data as string that generate from create_qr() method.

Parameters for check_payment() Method

• md5: Valid hash md5 from generate_md5() method of the correct transaction.

Parameters for check_bulk_payments() Method

• md5_list: md5 list of all transacrions generate from generate_md5() method.

Parameters for get_payment() Method

• md5: Valid hash md5 from generate_md5() method of the correct transaction.

Parameters for qr_image() Method

• qr: QR string to convert into an image from create_qr().
• output_path: Optional path to save the image. If not provided, returns a temp file path.
• format: Image format to export ('png', 'jpeg','webp', 'bytes', 'base64' or 'base64_uri'). Default: 'png'.
